TL;DR: In mixtures of substances with different taste qualities, the components can still be recognized but are usually perceived as less intense than when unmixed, which means sour substances show the least compression and sweetness, saltiness, and bitterness are compressed to greater extents.

TL;DR: The presence of testosterone in neonatal life plays a role in the masculinisation of open-field behavior and that its effect is partly mediated by the presence of cyclic ovarian secretions in the adult female rat and their absence in the male and TP treated female.

TL;DR: For instance, this paper found that primiparous females that raised litters to weaning and were tested for responsiveness to donor's pups 25 days postweaning exhibited an immediate onset of maternal responsiveness.

TL;DR: Differences between HO-DI and Wistar rats in open field behavior, in response threshold to electric footshock, and in a number of somatic endocrine parameters are reported and discussed.

TL;DR: It was concluded that estrogen is capable of inducing, not suppressing, maternal behavior in virgin rats and that the uterus may play an important but as yet undetermined role.

TL;DR: In this article, the feeding behavior of 37 albino rats was used to demonstrate that significant post-prandial correlations could be obtained from unordered raw data when actual intake was used as the measure of meal size.

TL;DR: The quantity and quality of food eaten by lactating female rats are critical for the emission and the synthesis of the maternal attractant, respectively, and the pups appear to learn to associate the caecotrophe odor specific to the maternal diet with an approach response.

TL;DR: The glucose-sensitive neurons in the rat lateral hypothalamic area which are inhibited by glucose microapplications through one of multibarreled micropipettes were facilitated by microapplication of free fatty acids (FFA).

TL;DR: A new method is proposed which makes possible quantitative analysis of neural excitability cycle changes and increases for fibers mediating bar pressing for rewarding brain stimulation are found at all C-T intervals.

TL;DR: The majority of 14 human observers lacking olfactory nerve function detected, by nasal inhalation, over one quarter of 31 chemicals commonly used in Olfactory research, indicating the trigeminal nerve may play an important role in human nasal chemoreception and that effective trigEMinal stimulants may be predictable on physicochemical grounds.

TL;DR: The results suggest that several areas contribute to the hyperreactivity that is usually attributed to septal lesions, including parts of the diagonal band of Broca and the accumbens nucleus.

TL;DR: Positive meal to postmeal interval correlations were evident in intact but not vagotomyized animals, whereas vagotomized animals displayed a meal to premeal interval correlation in the light phase that was not present in normal rabbits.

TL;DR: The results suggest that fearlike responses to DMT stimulation may be dependent upon brain serotonin levels and relatively insensitive to levels of brain catecholamines.

TL;DR: These studies show that it is possible to localize discrete areas in the amygdala which have specific effects on ingestive behaviors and it is suggested that the amygdala modulates on-going hypothalamic activity via the stria terminalis from the dorsomedial area and the ventral amygdalofugal pathway from the Ventral and lateral amygdala.

TL;DR: A model of the interaction between endocrine function and agonistic responding was developed that incorporates three specific hypotheses about the relactionship between hormones and agonism, and some directions for future research were proposed.

TL;DR: Behavioral testing after the infusion indicated that subjects who received ACTH/MSH 4-10 were less anxious and had better visual memory than control subjects but the predominant effect of the heptapeptide was to increase visual attention.

TL;DR: These ingestive responses produced by noradrenergic stimulation of the anterior perifornical hypothalamus were found to bear striking similarities to the rat's natural feeding behavior and premeal component of his natural food-associated drinking behavior.

TL;DR: It was concluded that neonatal androgens can affect open-field behavior and maze performance and argued that these sexually dimorphic behaviors probably do not require circulating androgens for their expression.

TL;DR: Measurement of home-cage food intake showed that the normal day-time depression of food intake was less marked in isolates than in socially-grouped animals.

TL;DR: Two adrenergically elicited phenomenon, namely, a suppression of drinking, was observed during and after the period of induced feeding, and Pharmacological analysis of the ingestive behaviors induced by l-norepinephrine or l-epinephrine indicated that the eating response was mediated by alpha-adrenergic receptors, whereas the drinking response involved the synergistic action of both alpha- and beta-adRenergic receptors.

TL;DR: Overeating was unmodified by the use of an equicaloric high protein diet even though total weight gain was reduced and hyperphagia and hypophagia upon termination of insulin treatment were directly related to the amount of insulin that had been administered.

TL;DR: Feeding, as well as responses to prey extracts, were found to be suppressed almost totally in the tongueless naive snakes, while a detongued adult readily ate although its behavior was abnormal.

TL;DR: It is concluded that neonatal androgens organize mechanisms which regulate subsequent body growth in the male rat, and that from puberty on ovarian secretions suppress the growth rate.

TL;DR: The observations on rhesus females indicated a systematic relationship between levels of food intake and reproductive condition in primates, and a positive correlation is noted between incidence of food rejection and levels of circulating estrogens.

TL;DR: Anisomycin was shown to cause a significant degree of amnesia for the escape component as well as the avoidance component of the learning in mice trained to avoid footshock in a T-maze.

TL;DR: Male rats were given a quinine adulterated fluid as their sole source of liquid for over 60 days, and after a latency of a few days, fluid intake stabilised at about 20 ml/day, with the water to food ratio close to 1.0 ml/g.

TL;DR: Anisomycin, an inhibitor of brain protein synthesis, was used to control the time and duration of protein synthesis occurring in mice after they were trained on a one-trial passive avoidance task and found that if synthesis was strongly inhibited for 6 to 8 hr, a high percentage of the animals was amnesic.

TL;DR: Responses of the rat chorda tympani nerve were obtained to stimulation of the tongue with both linearly rising anodal current of varying intensity and rate of rise and NaCl presented at different concentrations and rates of flow.

TL;DR: Results suggest that lateral hypothalamic lesions induce a metabolic impairment in rats with LH lesions, and an increase in core temperature was found in LH lesioned rats immediately following surgery and throughout the experimental period.

TL;DR: Bilateral lesions in the anterior aspects of the zona incerta of male rats reliably reduced the feeding response to systemically administered 2-deoxy-D-glucose, and Insulin-induced feeding remained intact.
