Effects of repeated administration of corticotropin-releasing factor on schedule-controlled behavior in rats.
To examine the effects of repeated administration of corticotropin-releasing factor (CRF) on behavior, rats were administered ICV injections of either CRF or saline on alternate days for 10 days prior to performing on a multiple fixed-interval (FI) 60 s/fixed-ratio (FR) 20 schedule for food reinforcement. A daily session consisted of 10 components of each schedule that alternated, starting 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...
متن کاملEffects of azaprophen, scopolamine and trihexyphenidyl on schedule-controlled behavior, before and after chronic physostigmine.
The effects of the muscarinic acetylcholine receptor antagonists, azaprophen (0.3-10.0 mg/kg), scopolamine (0.01-3.0 mg/kg) and trihexyphenidyl (0.3-10.0 mg/kg) were examined in rats using a VI 18 s schedule of food reinforcement, before and after chronic physostigmine administration. All three compounds produced dose-dependent decreases [corrected] in the rate of responding. Scopolamine was mo...
متن کاملEffect of once weekly treatment with 3,4-methylenedioxymethamphetamine on schedule-controlled behavior in rats.
The present study examined the effects of 3,4-methylenedioxymethamphetamine (MDMA), before and after once a week dosing, on the behavior of rats responding under a fixed ratio 20 schedule of reinforcement. Acutely, cumulative doses of MDMA dose-dependently decreased responding when compared to a series of water injections. Rats were then separated into two groups, one of which received only wee...
متن کاملEffects 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...
