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.
Entrainment of respiration to repetitive finger tapping
Physiological Psychology - Tập 3 - Trang 345-349 - 2013
Subjects were instructed to synchronize finger tapping with visual signals of various frequencies. It was found that breathing rate became entrained to tapping rate if the latter fell within a range of two breaths per minute of the subject’s previous breathing rate. Entrainment did not occur when the subject merely monitored the visual stimuli but only during performance of tapping. The effect occ......
Hemispheric amplitude asymmetries in the auditory evoked potential with monaural and binaural stimulation
Physiological Psychology - Tập 3 - Trang 169-171 - 2013
The present experiment examined auditory evoked potentials (AEPs) under three conditions of auditory stimulation: left ear, right ear, and the two ears simultaneously. It was hypothesized that the white-noise stimulus would result in higher amplitude AEPs in the contralateral hemisphere as compared to the ipsilateral. This was confirmed. There were no latency differences in AEPs recorded from over......
A comparison of the effects of medial frontal, dorsomedial thalamic, and combination lesions on discrimination and spontaneous alternation in the rat

Saccharin ingestion, weight loss, and mortality in rats
Physiological Psychology - Tập 2 - Trang 323-325 - 2013
Rats maintained on 10 g of food and saccharin solutions suffered weight loss and mortality compared with controls maintained on 10 g food and water. Frequency of death was related to amount and concentration of the ingested solution, while weight loss was related only to concentration and absolute amount of saccharin intake.
Further results obtained with pairing of the “kindling effect” and the “transfer experiment”
Physiological Psychology - Tập 3 - Trang 237-239 - 2013
Previous experiments indicated that the development of clonic convulsions could be retarded by intraperitoneal injections of brain homogenate supernatant from male Wistar rats which had convulsed via amygdaloid electrical stimulation if two or more brain equivalents were used. Six experiments were conducted employing intracerebral injections. Although significant differences appeared in one experi......
A factor analysis of data from sequential alternation of amygdaloid stimulation: A replication
Physiological Psychology - Tập 7 - Trang 437-443 - 2013
Data from a number of sequential alternation experiments for 125 subjects were factor analyzed to determine the number of common factors present. Three measures (mean latency of convulsion, mean number of trials to, six convulsions, mean duration of convulsions) were evaluated by principal components analyses. The presence of two factors was suggested in the latency, criterion, and duration measur......
The acquisition of a Pavlovian conditioned response in septally damaged rabbits: Role of a competing response
Physiological Psychology - Tập 2 - Trang 133-136 - 2013
Enhanced acquisition of a classically conditioned eyelid response was found following septal injury in rabbits. Eye-opening behavior was four times more frequent in the control Ss. This suggests that faster acquisition is a function of fewer competing responses which might interfere with elaboration of the conditioned response.
