Tales of thirsty desert travelers and oasis mirages are consistent with our intuitions that appetitive state can influence what we see in the world. Yet there has been surprisingly little scrutiny of this appetitive modulation of perception. We tested whether dehydrated subjects would be biased towards perceptions of transparency, a common property of water. We found that thirsty subjects have a greater tendency to perceive transparency in ambiguous stimuli, revealing an ecologically appropriate modulation of the visual system by a basic appetitive motive.}, Doi = {10.1068/p3266}, Key = {fds251880} } @article{fds251881, Author = {Myers, KP and Hal, WG}, Title = {Experience with Drinking While Dehydrated is Required for Weanling Rats to Acquire an Appetitive Response to Cellular Dehydration}, Journal = {Development Psychobiology}, Volume = {38}, Pages = {145-153}, Year = {2001}, Key = {fds251881} } @article{fds251878, Author = {Coyle, S and Arnold, HM and Goldberg-Arnold, JS and Rubin, DC and Hall, WG}, Title = {Olfactory conditioning facilitates diet transition in human infants.}, Volume = {37}, Number = {3}, Pages = {144-152}, Publisher = {Wiley}, Year = {2000}, Month = {November}, ISSN = {0012-1630}, url = {http://www.ncbi.nlm.nih.gov/pubmed/11044862}, Abstract = {We evaluated whether Pavlovian conditioning methods could be used to increase the ingestion of non-preferred solutions by formula-fed human infants. In baseline measures, 5-7 month old infants sucked less frequently and consumed less water than regular formula. During a 3-day olfactory conditioning period, parents placed a small scented disk, the conditioned stimulus, on the rim of their infants' formula bottle at every feeding. Following this training, infants' responses to water were tested when their water bottles had a disk scented with the training odor, a novel odor, or no odor. Infants tested with the training odor sucked more frequently and consumed significantly more water than they had at baseline. Infants tested with no odor or a novel odor consumed water at or below baseline levels. These data demonstrate that olfactory conditioning can be used to enhance ingestion in infants and suggest that such methods may be useful for infants experiencing difficulty when making transitions from one diet to another.}, Doi = {10.1002/1098-2302(200011)37:3<144::aid-dev3>3.0.co;2-z}, Key = {fds251878} } @article{fds251877, Author = {Myers, KP and Hall, WG}, Title = {Conditioned changes in appetitive and consummatory responses to flavors paired with oral or nutrient reinforcement among adult rats.}, Journal = {Physiology & behavior}, Volume = {68}, Number = {5}, Pages = {603-610}, Year = {2000}, Month = {March}, ISSN = {0031-9384}, url = {http://www.ncbi.nlm.nih.gov/pubmed/10764888}, Abstract = {Recent studies of the behavioral organization of conditioned flavor preferences have suggested the involvement of at least two separate learning systems-an appetitive response system sensitive to the oral hedonic properties of the reinforcer, and a consummatory response system sensitive to its nutrient properties. However, these prior studies were conducted with weanling rats, that differ from adults in terms of their prior experience with food, their learning competencies, and the peculiar ontogenetic constraints on their behavior. It is, therefore, unknown whether flavor preference behaviors are similarly organized in adult rats. In this experiment, adult rats were trained to associate a specific CS flavor with either the sweet taste or the postingestive nutrient effects of sucrose. Conditioned appetitive orienting and consummatory oral responding to the CS flavors were then measured. Unlike weanling rats, adult rats exhibited both conditioned appetitive behavior and conditioned consummatory behavior in response a CS that was previously paired with either oral hedonic or nutrient reinforcement. These results suggest a set of important developmental changes in the neurobehavioral mechanisms of flavor preference learning in the postweaning period.}, Doi = {10.1016/s0031-9384(99)00209-7}, Key = {fds251877} } @article{fds251879, Author = {Hall, WG and Arnold, HM and Myers, KP}, Title = {The acquisition of an appetite.}, Journal = {Psychological science}, Volume = {11}, Number = {2}, Pages = {101-105}, Year = {2000}, Month = {March}, ISSN = {0956-7976}, url = {http://www.ncbi.nlm.nih.gov/pubmed/11273415}, Abstract = {Unlike older animals, weanling-age rats do not seek water to drink when they are dehydrated, despite the fact that a physiological sensitivity to dehydration is present very soon after birth. We demonstrate here that the appetitive behaviors needed to approach and obtain water become linked to dehydration only as a result of specific postnatal learning experience. Preventing early experience with dehydration retards the developmental emergence of dehydration-induced, water-oriented behavior in young rats. But a single pairing of water with dehydration can establish an appetitive response. These findings reveal a critical role of early learning in the development of goal-oriented behavior. Such a learning process is potentially characteristic of other behavioral systems, from the most basic appetites to complex motives.}, Doi = {10.1111/1467-9280.00223}, Key = {fds251879} } @article{fds251811, Author = {Myers, KP and Hall, WG}, Title = {Evidence that oral and nutrient reinforcers differentially condition appetitive and consummatory responses to flavors.}, Journal = {Physiology & behavior}, Volume = {64}, Number = {4}, Pages = {493-500}, Year = {1998}, Month = {June}, ISSN = {0031-9384}, url = {http://www.ncbi.nlm.nih.gov/pubmed/9761223}, Abstract = {Rats tend to increase their intake of a flavor that has previously been paired with either sweet taste or with caloric repletion. However, it is unclear whether such a change in intake is caused by changes in appetitive behaviors such as orienting and approach, or changes in consummatory behaviors and oral responsiveness. Also, it is unclear whether oral reinforcers (sweetness) and postingestive reinforcers (nutrients) lead to the same kinds of behavioral change. In the current experiments, weanling rats with oral and gastric cannulas repeatedly experienced a flavor paired with either sweetness, high caloric density, or neither. Rats were then tested for differences in appetitive olfactory orienting and consummatory oral responsiveness elicited by the flavor. Results suggest that oral reinforcement (sweetness) produces conditioning of appetitive responding to the flavor, while postingestive reinforcement produces conditioning of consummatory responding. A second experiment indicates that these behavioral changes are specific increases in responsiveness conditioned by flavor + unconditioned stimulus (US) pairing, and are unlikely to be nonspecific effects of daily unconditioned stimulus exposure.}, Doi = {10.1016/s0031-9384(98)00106-1}, Key = {fds251811} } @article{fds251812, Author = {Swithers, SE and Westneat, MW and Hall, WG}, Title = {Electromyographic analysis of oral habituation in rat pups.}, Journal = {Physiology & behavior}, Volume = {63}, Number = {2}, Pages = {197-203}, Year = {1998}, Month = {January}, ISSN = {0031-9384}, url = {http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:A1998YK64800007&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=47d3190e77e5a3a53558812f597b0b92}, Abstract = {Rat pups show decreases in mouthing activity in response to a series of repeated oral infusions of a diet. This decrease in mouthing activity has been termed "oral habituation" and these changes have been readily recorded with simple behavioral observations. Oral habituation appears to be a component of satiety in young rats. In the present study, to more specifically characterize changes in motor response topography during habituation in muscle groups used for mastication, mouthing activity was recorded by implanting fine wire electromyographic electrodes in the superficial masseter, anterior digastric, sternohyoideus, and genioglossus muscles of 12-day-old rat pups. During testing, pups received a series of brief oral infusions of a 10% sucrose diet delivered through an oral cannula. The results demonstrated that mouthing activity as observed and scored behaviorally was highly correlated with mouthing behavior recorded by EMG, with oral habituation distinctly emerging in both measures. In addition, the pattern of motor activity in the four masticatory muscles changed during the course of oral habituation. Within the minute following a single infusion, the cycle frequency, duration of activity, and relative onset time of activity in the four muscles changed. In addition, across the course of habituation, both cycle frequency and relative onset times of muscle activity changed. These results demonstrate the general reliability of behavioral observations of masticatory motor activity in young rats and provide further information on how the pattern of activity of muscles involved in the mouthing motor pattern is altered during the course of oral habituation.}, Doi = {10.1016/s0031-9384(97)00421-6}, Key = {fds251812} } @article{fds251813, Author = {Myers, K and Hall, WG}, Title = {Sensitization of ingestive responding and activity in developing rats}, Journal = {Behav.

In the experiment, the analysis of lateralized olfactory learning in 6-day-old rat pups was extended by an evaluation of the consequences of aversive reinforcers in a unilateral olfactory conditioning paradigm. An olfactory aversion was conditioned by delivering a mild footshock to animals in the presence of a novel odor. Olfactory stimulation was confined to one naris and corresponding olfactory bulb by inserting a soft rubber plug into the opposite naris. This lateralization in processing resulted in unilateral memory for the odor aversion that was only expressed when the trained naris was open during an odor preference test. The hypothesis that the hedonic value (or valence) component of conditioning is represented in structures that are unilaterally accessed during training and testing is discussed.}, Doi = {10.1037//0735-7044.109.3.563}, Key = {fds251814} } @article{fds251815, Author = {Swithers, SE and Hall, WG}, Title = {Does oral experience terminate ingestion?}, Journal = {Appetite}, Volume = {23}, Number = {2}, Pages = {113-138}, Year = {1994}, Month = {October}, ISSN = {0195-6663}, url = {http://www.ncbi.nlm.nih.gov/pubmed/7864607}, Abstract = {Using data from studies of ingestive behavior in developing rat pups we demonstrate how oral experience can contribute to the termination of ingestion. In rat pups, repeated oral stimulation with sweet solutions causes a decline in oral responsiveness. The diminished responsiveness is specific to the flavor of the stimulus experienced orally and can persist for several hours. We suggest that this experience-based decrement in responsiveness is best considered "oral habituation" and that oral habituation largely accounts for the onset of satiety. Post-ingestive feedback signals may have their influence through the oral habituation process or act in the context of oral habituation. Oral habituation is also shown to depend on the pattern of stimulus presentation, a phenomenon that adds considerable complexity to assessing the contributions of oral experience to satiety. The concept of oral habituation may be useful in understanding the immediate control of ingestion and the moment-to-moment expression of ingestive behavior in adult animals.}, Doi = {10.1006/appe.1994.1041}, Key = {fds251815} } @article{fds251816, Author = {Swithers-Mulvey, SE and Hall, WG}, Title = {Integration of oral habituation and gastric signals in decerebrate rat pups.}, Journal = {The American journal of physiology}, Volume = {265}, Number = {1 Pt 2}, Pages = {R216-R219}, Year = {1993}, Month = {July}, ISSN = {0002-9513}, url = {http://www.ncbi.nlm.nih.gov/pubmed/8342690}, Abstract = {During a series of oral infusions of a sweet solution, the ingestive responses of young rat pups habituate; pups stop responding to the infusions even when their stomachs are empty and the infused diet is nonnutritive. The rate of this oral habituation is enhanced by the addition of gastric fill signals, even in decerebrate pups. In intact but not in decerebrate pups, prior deprivation gates out the influence of gastric fill on habituation.

Normal-weight, nondieting young adults consumed each of the meals for breakfast on separate days. The main finding was that tasty versions of high-FAT and high-CHO meals were more satiating than nutritionally identical bland meals, as indicated by a greater decrease in hunger ratings following the tasty meals. Changes in blood glucose and FFA were related to meal nutrient composition, but not to meal sensory properties. High-CHO meals tended to be more satiating than high-FAT meals. Consumption of each of the meals produced a similar decrease in pleasantness ratings of food-related tastes. Intake of carbohydrates was significantly higher at a self-selected lunch 5.25 h following a tasty breakfast.

The question was asked: Is suckling a neuromuscular precursor to chewing, or are suckling and chewing independent systems? Electromyograms (EMGs) were recorded in rat pups of ages 6, 9, 12, 15, 18, and 21 days from the superficial masseter, anterior digastric, sternohyoideus, and genioglossus muscles during suckling and chewing. The EMG patterns of the 3 components of suckling behavior (nipple attachment, rhythmic sucking and the stretch response) are distinctive from one another and reflect the musculoskeletal biomechanics of suckling. Chewing EMGs are present by 12 days of age and attain the adult pattern by 18-21 days of age. During nipple attachment, pups exhibit a motor pattern that is similar to that of adult chewing, but other aspects of suckling differ from chewing in some EMG features.

This control of ingestion is revealed in the decreases in mouthing responses of rat pups to repeated oral stimulation, a phenomenon that is well described as oral habituation. The present study examined the neural basis for oral habituation by examining the responses of decerebrate 10-day-old rat pups to repeated, brief infusions of a sucrose solution. Like neurologically intact pups, decerebrate pups showed distinct decreases in mouthing responses following a series of oral infusions. Thus, oral habituation is present in the hindbrain. Although intact pups demonstrated sensitization by showing increased responding to the first few stimulus presentations, decerebrates failed to show a sensitization to the stimulation. These results suggest that while the brainstem alone is sufficient for the expression of oral habituation, the forebrain also influences oral responsivity in intact animals.}, Doi = {10.1016/0031-9384(92)90189-9}, Key = {fds251820} } @article{fds251819, Author = {Hall, WG and Swithers-Mulvey, SE}, Title = {Developmental strategies in the analysis of ingestive behavior.}, Journal = {Annals of the New York Academy of Sciences}, Volume = {662}, Pages = {1-15}, Year = {1992}, Month = {January}, ISSN = {0077-8923}, url = {http://www.ncbi.nlm.nih.gov/pubmed/1456634}, Doi = {10.1111/j.1749-6632.1992.tb22851.x}, Key = {fds251819} } @article{fds251821, Author = {Phifer, CB and Denzinger, A and Hall, WG}, Title = {The early presence of food-oriented appetitive behavior in developing rats.}, Journal = {Developmental psychobiology}, Volume = {24}, Number = {7}, Pages = {453-461}, Year = {1991}, Month = {November}, ISSN = {0012-1630}, url = {http://www.ncbi.nlm.nih.gov/pubmed/1797591}, Abstract = {The appetitive behavior of 3- to 6-day-old rat pups was studied by testing their ability to direct their ingestive behavior to a restricted food source.

The general locomotor activation of pups in this latter group appeared to interfere with their ability to direct their behavior to the restricted source.

Unfortunately, when sampling is restricted to predefined areas, important topographic information is lost along with the ability to reveal an unexpected change in neural activity. To preserve the rich topographical detail of metabolic information and to enhance the capacity to uncover novel areas of altered metabolic activity, we have developed a system for averaging entire images from 2-DG autoradiograms and for comparing the average images from two experimental groups by creating an image of differences. This procedure does not rely on sampling only preselected regions, but still allows statistical comparisons between experimental groups.

The ability of 12-day-olds to access unilaterally stored memories from the untrained side of the olfactory system permitted us to further explore the locations of olfactory memories and the routes of access to these memories. We report here that when preference memories were tested from the untrained side after selective fiber-tract transections on the trained side: (1) transection of the anterior limb of the anterior commissure at various rostral-caudal levels prevented retrieval of odor memories; (2) transection of the posterior limb did not disrupt memory access; and (3) transection of the olfactory peduncle on the trained side, thereby removing the contribution of the trained olfactory bulb, did not eliminate access to odor-preference memories. These findings suggest that access to contralateral olfactory memories is subserved by the anterior limb of the anterior commissure, probably through access to its most distal projections to the anterior olfactory nucleus and the anterior piriform cortex, and that retrieval of preference memories does not require access to the trained olfactory bulb. © 1990, Psychonomic Society, Inc..

In these experiments regional neural metabolic activity, as assessed by semiquantitative deoxyglucose (DG) autoradiography, was related to dehydration and ingestive behavior in 6-day-old rat pups. During simple ingestive responding, changes in relative DG uptake, representative of changes in neural metabolic activity, occurred primarily in hindbrain sensory and motor nuclei. Producing cellular dehydration resulted in activity changes primarily in the basal forebrain. When pups were dehydrated and allowed to ingest during the DG-uptake period, activity changes were seen in both the hindbrain and forebrain areas that responded to ingestion or dehydration alone as well as in regions that were not affected by either manipulation alone. These latter changes, which result from an interaction of behavioral and physiological stimuli, call attention to areas that may subserve motivational aspects of behavior. Extracellular dehydration was found to produce fewer and different forebrain responses in neural metabolic activity. During ingestion, the only effects of extracellular dehydration that overlapped with those of cellular dehydration appeared in circumventricular hypothalamic regions and brain stem motor nuclei. Thus, there appeared to be only a limited final common pathway for these two types of dehydration-induced drinking. Taken together, these findings in infant rats depict distributed neural systems subserving ingestion and responding to state change.

Preweanling rats were exposed to an odor (CS+) paired with footshock and a different odor (CS−) that was explicitly unpaired with footshock. The rats were then immediately tested for their preference between the CS+ and CS− odors. In Experiment 1, animals trained at 12 or 18 days of age showed equivalent conditioned aversions to the CS+. When the significance of the cues was reversed, the younger animals showed rapid reversal learning; that is, their aversion to the original CS-I- was displaced by an aversion to the original CS−. However, the 18-day-old animals were slower to acquire discrimination reversal. In Experiment 2, a similar pattern of results emerged when animals were given separate preference tests involving the CS+ versus a novel odor, or the CS− versus a novel odor. In Experiment 3, intact 18-day-old rats and 18-day-olds with damage to the septum and fornix showed equivalent conditioned aversions to the CS+. In contrast to the intact animals, however, the lesioned rats showed rapid reversal of the discrimination, which resembled that of intact 12-day-olds. Thus, there appears to be a dramatic change in reversal learning of conditioned odor aversions in rats after the second week of postnatal life.

Animals expressed a conditioned orientation towards cedar if tested with the trained nostril open. No such conditioning was observed if the untrained nostril was open during testing. Further, when individual pups received cedar odor/milk pairings with one nostril open and orange odor/milk pairings with the other open, they expressed a conditioned preference for orange when tested with the orange-trained nostril open, and a preference for cedar when tested with the cedar-trained nostril open. Classically conditioned oral responses (mouthing) also appeared to be lateralized. However, no such unilateral conditioning occurred with respect to behavioral activation, which is also conditioned in this paradigm. Increases in activity to the odor CS were observed regardless of whether the trained or untrained nostril was open during testing.

As late as 20 days of age, suckling deprivation induced suckling largely through its stimulus-deprivation effects (olfactory, gustatory, somesthetic, and proprioceptive sensations) rather than through its food-deprivation effects. By 25 days of age, the type of oral stimulation that led to suckling satiety expanded; oral stimulation provided by independent feeding acquired characteristics that allowed it also to inhibit suckling. This developmental change in the stimuli that modulated suckling did not appear to be critically dependent on sensory changes in the dam or experiential events within the litter.

During development, suckling normally declines after 10 days and is abandoned after 30 days. It was found that (a) methysergide, a serotonin (5-HT) receptor blocker, reinstated suckling behavior in pups 15 days of age and older but had no effect on the suckling of 10-day old pups, (b) quipazine, a 5-HT receptor agonist, inhibited suckling of pups 10 days of age and older, (c) methysergide pretreatment blocked the quipazine inhibition of suckling, and (d) metergoline, another 5-HT blocker, also stimulated suckling, and fenfluramine, a 5-HT releaser, blocked suckling in deprived pups. Together, these data support the hypothesis that a serotonergic inhibitory mechanism modulates the suckling of weaning-age rats. These pharmacological manipulations of 5-HT appear to alter specific components of suckling behavior involved in its initiation and maintenance but do not appear to alter a general hunger system.}, Doi = {10.1037/h0077592}, Key = {fds251857} } @article{fds251858, Author = {Kornblith, C and Hall, WG}, Title = {Brain transections selectively alter ingestion and behavioral activation in neonatal rats}, Journal = {J.
