The effect of limbic damage on the retention and performance of a runway response
(Elsevier, 1966-07)
Rats were trained to run a linear runway while hungry for food. Then they were tested for retention, continued performance levels, and extinction after recovery from bilateral damage of the hippocampus, the septal area, ...
Hippocampal lesions and active avoidance
(Elsevier, 1968-09)
Rats with lesions of the hippocampus were impaired relative to normal rats in the acquisition and retention of a one-way active avoidance task, but were superior to normal and partially neodecorticate rats in the acquisition ...
Drug-induced modifications in sexual behavior and open field locomotion of male rats
(Elsevier, 1969-09)
Several drugs were selected for sexual and open field behavioral testing, according to the following criteria: they are known synergists or antagonists of presumptive neurotransmitters; they modify behaviors thought to be ...
Parametric studies of the response decrement produced by mechanical stimuli in the protozoan, Stentor coeruleus
(Wiley Subscription Services, Inc., A Wiley Company, 1969)
A decrement in the probability of eliciting a response is observed during the course of repetitive stimulation in many response systems of both metazoa and protozoa. Those forms of metazoan response decrement called ...
Emotional responses toward humans in monkeys with selective frontal lesions
(Elsevier, 1968-03)
Monkeys with lateral or orbital frontal lesions, operated controls with inferotemporal lesions and unoperated controls were tested for aggressive and aversive responses toward humans as judged by three observers. Contrary ...
Memory in mammals: Evidence for a system involving nuclear ribonucleic acid
(Elsevier, 1966-02)
The learning of an avoidance response was confined to one hemisphere in rats by starting cortical spreading depression in the other. Removing the medial (but not anterior or posterior) cortex of the trained hemisphere ...
Environmental control of amnesic effects of various agents in goldfish
(Elsevier, 1969-03)
Fish given a single electroconvulsive shock or intracranial administration of puromycin, acetoxycycloheximide, or KCl immediately following shock avoidance training show amnesia on retraining days later. When the treatments ...
Electrophysiological studies of the protozoan, Stentor coeruleus
(Wiley Subscription Services, Inc., A Wiley Company, 1969)
Transmembrane potentials and membrane characteristics of Stentor coeruleus were studied by means of microelectrodes and standard electrophysiological techniques. Intracellular resting potentials were found to be variable ...
The effects of preliminary training conditions upon DRL performance in the hippocampectomized rat
(Elsevier, 1966-04)
Rats suffering radical bilateral hippocampal destruction, destruction of the posterolateral neocortex, and normal animals were trained on a DRL 20 reinforcement schedule in an operant conditioning situation. Half of the ...
Transfer of brightness discrimination under unilateral spreading depression
(Elsevier, 1969-09)
Rats trained under unilateral cortical spreading depression on a brightness discrimination task for water reinforcement will show little or no transfer when retrained with the contralateral cortex depressed. The current ...
