Effects of mephenytoin on schedule-controlled responding in the pigeon.
Acute and chronic effects of mephenytoin (30-360 mg/kg) were examined in pigeons responding under a multiple fixed-ratio 50 fixed-interval 90-sec schedule of food delivery. The highest dose administered acutely (240 mg/kg) produced substantial reductions in rate of responding under both components of the multiple schedule; the effects of other doses were small and inconsistent. With chronic exp...
متن کاملEffects of d-amphetamine on temporal distributions of schedule-induced polydipsia.
Food-deprived rats were divided into four groups according to the equal interval and time durations of a multiple fixed-interval, fixed-time schedule (15, 30, 60, and 120 s). Fixed-time components were signaled by a tone and lever withdrawal. d-Amphetamine (0.25-4.0 mg/kg) produced similar dose-dependent reductions in the drinking and licking induced by fixed-interval and fixed-time schedules. ...
متن کاملSchedule-induced electrodermal responding in children.
The current studies were designed to determine whether different intermittent schedules of reinforcement would have a differential effect on the skin conductance responses (SCRs) of children in the 8-12-year-old age range. Results of two experiments indicated that the amplitude of children's SCRs immediately following the occurrence of reinforcement were a function of the schedule of reinforcem...
متن کاملEffects of -Hydroxybutyrate (GHB) on Schedule-Controlled Responding in Rats: Role of GHB and GABAB Receptors
-Hydroxybutyrate (GHB), a metabolite of -aminobutyric acid (GABA), is an increasingly popular drug of abuse and was recently approved for the treatment of narcolepsy (Xyrem). GHB and GABA receptors have been implicated in mediating effects of GHB; however, the relative importance of each of these receptors is unclear. This study evaluated the effects of selective antagonists in combination with...
متن کاملEffects of chronic caffeine administration on respiration and schedule-controlled behavior in rhesus monkeys.
The effects of chronic caffeine administration on ventilation and schedule-controlled behavior were studied in 12 adult rhesus monkeys. In seated subjects prepared with a head plethysmograph, ventilation was measured during exposure to air (normocapnia) and to elevated levels of CO2 (3%, 4% and 5%) mixed in air (hypercapnia). Acute administration of caffeine (10.0-30.0 mg/kg i.m.) produced mark...
