Modulation of taste affect by hunger, caloric satiety, and sensory-specific satiety in the rat.
Human judgements of the pleasure of sweetness have been reported to be modulated by caloric hunger, satiety, and sensory-specific satiety. This study examined both hedonic and aversive facial/somatic reactions to taste in the rat, in order to confirm the relation of hunger and satiety to taste affect, and to assess whether affective modulation depends upon the cognitive factors that mediate hum...
متن کاملLateral hypothalamic activity indicates hunger and satiety states in humans
Lateral hypothalamic area (LHA) local field potentials (LFPs) were recorded in a Prader-Willi patient undergoing deep brain stimulation (DBS) for obesity. During hunger, exposure to food-related cues induced an increase in beta/low-gamma activity. In contrast, recordings during satiety were marked by prominent alpha rhythms. Based on these findings, we have delivered alpha-frequency DBS prior t...
متن کاملCharacteristics of intermittent mitochondrial transport in guinea pig enteric nerve fibers.
Enteric neurons controlling various gut functions are prone to oxidative insults that might damage mitochondria (e.g., intestinal inflammation). To resume local energy supply, mitochondria need to be transported. We used MitoTracker dyes and confocal microscopy to investigate basic characteristics of mitochondrial transport in guinea pig myenteric neurites. During a 10-s observation of 1 mm ner...
متن کاملKaryotype of Hairless Guinea pig
Chromosomal patterns of experimental animals are useful tools for cytogenetics research and animal breeding. Chromosome investigations of the hairless guinea pig are rare, therefore, karyotype of hairless guinea pigs (twelve male and female) was studied using metaphase spreads of bone marrows and G banding techniques. The chromosomes diploid number was 2n= 64 and polymorphism of three type chro...
متن کاملNeural Control of Hunger, Appetite, and Satiety **
Hunger, appetite, and satiety are often regarded as problems in the physiology of digestion. In recent years, however, they have been studied more and more commonly as functions of the brain. This latter point of view, i.e., neurophysiology, is used in the paper which follows, and the regulation of food intake is here described in terms of mechanisms and reactions that characterize the nervous ...
