The effects of 17 h food deprivation and stimulation by five concentrations (0.05-0.8 M) of sucrose solutions on the licking behavior of rats were investigated. Food deprivation increased the intake of the three lowest concentrations (0.05, 0.1, and 0.2 M) but had no effect on the volume ingested of the two highest concentrations (0.4 and 0.8 M). Food(More)
Behavioral and electrophysiological features of sleep and wakefulness were studied in chronically implanted adult parakeets, Aratinga canicularis. Four states of vigilance were observed: (1) Wakefulness. It is divided into active and passive. During this state there are generalized motor manifestations which are more frequent and intense in active(More)
Individuals of Gopherus flavomarginatus, previously adapted to experimental conditions were chronically implanted for polygraphic recordings. Four different states of vigilance were observed:. Active wakefulness, quiet wakefulness, quiet sleep and active sleep. EEG was polymorphic and irregular showing a decreasing tendency in frequency and amplitude when(More)
OBJECTIVE To analyze the impact of moderate physical exercise on the total and differential leukocyte counts and red blood cell count of 36 sixty-day-old adult male Wistar rats subjected to early malnourishment. METHODS The rats were divided in nourished (N - casein 17%) and malnourished groups (M - casein 8%) and thesegroups were then subdivided in(More)
It has been reported that the addition of Acarbose, a alpha-glucosidase inhibitor, to a carbohydrate solution blocks a preference that otherwise would be displayed for that solution. One interpretation of those results is that the alteration in preference was caused by the diminished postabsorptive nutritive value of the diet due to the inhibition of(More)
Recently reported sham feeding studies have revealed that the rate of ingestion of liquid diets early in the ingestion interval is under the associative control of postingestive events occurring in the stomach and intestine. This study investigated the possibility that gastrointestinal filling induced by adding the nonabsorbable sugar alcohol mannitol to a(More)
