Effects of septal lesions on open-field gregariousness in rats reared prior to surgery in group versus individual cages
Physiological Psychology - Tập 13 - Trang 107-110 - 2013
Septal lesions were given to adult animals which had been reared in isolation or in group cages from 30–90 days of age. Septal lesions and isolated rearing produced additive increases in open-field contact time. These results were similar to those observed in a previous study in which septal lesions were produced in infancy and followed by differential housing. Emotionality and activity were also ......
Effects of Δ-9-tetrahydrocannabinol on the slope of auditory generalization gradients in rats
Physiological Psychology - Tập 4 - Trang 145-148 - 2013
Groups of rats were given 2, 4, or 6 mg/kg Δ-9-tetrahydrocannabinol (Δ-9-THC) during shuttle-avoidance training and auditory generalization testing in extinction. Although the drug had no discernible effect on acquisition performance, there was a dose-dependent influence on the slopes of the generalization gradients. It was concluded that Δ-9-THC can affect the extent of auditory generalization du......
Fornix lesions: Effects on active and passive avoidance behavior
Physiological Psychology - Tập 3 - Trang 201-204 - 2013
Twenty-four fornix-lesioned and 16 sham-operated rats were tested on one-way active avoidance acquisition, subsequent passive avoidance of the previously safe compartment, and acquisition and extinction of the passive avoidance of an electrified foodcup. Rats with lesions of the fornix made significantly more errors than controls in learning the one-way active avoidance acquisition task and had si......
Postconditioning CS-alone exposure as a source of interference in a taste aversion paradigm
Physiological Psychology - Tập 6 - Trang 255-260 - 2013
Two studies were conducted to study the effects of unpaired sucrose (CS) experiences on the acquisition, retention, and reacquisition of a sucrose aversion. In Experiment 1, rats received 0, 1, or 3 preconditioning CS exposures and/or 0, 1, or 3 postconditioning CS exposures. Sucrose exposures prior to conditioning interfered with the acquisition of a sucrose aversion, while sucrose-only experienc......

The effects of stimulation of the amygdala on food and water intake in rabbits
Physiological Psychology - Tập 6 - Trang 61-64 - 2013
The amygdala is supposed to have a dual modulatory influence on instigating and inhibiting central functions of alimentary behavior. Electrical stimulation of the basolateral amygdala in rabbits suppressed food and water intake during stimulation but had no aftereffects. Stimulation of the corticomedial amygdala had no discernible effects on food and water intake.

Appetite suppression caused by CCK is diet specific in VMH-lesioned rats
Physiological Psychology - Tập 7 - Trang 67-69 - 2013
Intraperitoneal injections of the C-terminal octapeptide of cholecystokinin-pancreozymin (CCK) failed to inhibit 5.5-h-fasted feeding of a high-fat diet in rats with electrolytic lesions of the ventromedial hypothalamus. Similar injections significantly reduced the intake of a high-fat diet in sham-lesioned controls. These results are consistent with Powley’s (1977) cephalic phase hypothesis (CPH)......
The effect of food deprivation on escape from electrical stimulation of the VMH
Physiological Psychology - Tập 4 - Trang 233-237 - 2013
Rats with permanently implanted intracranial electrodes were trained in a shuttlebox to escape from intermittent electrical stimulation of the ventromedial hypothalamus. Their latency to escape was measured under different degrees of food deprivation (0, 21, and 45 h). Latency was found to decline with increasing deprivation. It is argued that this finding is evidence against the hypothesis that t......
