Super-stereotypy I: Enhancement of a complex movement sequence by systemic dopamine D1 agonists
(John Wiley & Sons, Inc., 2000-09-01)
Peripheral administration of D1 dopamine agonists elicits grooming behavior from rodents. The present study examined grooming behavior and the relative probability and stereotypy of a natural sequence of grooming movements ...
Epilepsy, neuropsychological deficits, and EEG lateralization
(Elsevier, 1987)
One hundred eight epileptic patients (59 men, 49 women; 55% partial seizures, 45% generalized) were examined on 45 indices comprising a modified Halstead Neuropsychological Test Battery. Factor analyses identified five ...
An inability of [gamma]-acetylenic GABA to block eating evoked by hypothalamic stimulation
(Elsevier, 1980)
Several lines of evidence have implicated the nigrostriatal dopamine system and the neocortex for eating occurring either spontaneously or in response to electrical stimulation of the lateral hypothalamus (ESLH). GABA-ergic ...
Changes in medial cortical blood flow with a stimulus-response compatibility task
(Elsevier, 1994-02)
Previous work has suggested that human subjects engaged in tasks, like the Stroop task, that require response selection utilize the medical frontal cortex. We used positron emission tomography to measure blood flow changes ...
Brainstem systems mediate the enhancement of palatability by chlordiazepoxide
(Elsevier, 1988-05-03)
Previous studies have indicated that the benzodiazepine receptor complex is involved in enhancing taste palatability after chlordiazepoxide (CDP) administration. Positive, palatability-dependent ingestive reactions elicited ...
Extrinsic current and flash sensitivity in turtle cones
(Elsevier, 1994-02)
The effects of hyperpolarizing current and background light on intracellular responses of red cones in turtle were compared. Even though a background light always reduced response amplitude, hyperpolarizing current did so ...
Taste responsiveness, weight loss, and the ponderostat
(Elsevier, 1973-11)
Rats which lost weight due to exercise showed increased acceptance of good tasting food and increased rejection of bad tasting food. This indicates that energy deficit results in heightened taste responsiveness and suggests ...
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 ...
Flicker fusion characteristics of rod photoreceptors in the toad
(Elsevier, 1983)
Critical fusion frequency (CFF) of toad rods was examined at various intensities using intracellular recordings. Data were compared to CFF measurements (as a function of intensity) obtained with the electroretinogram (ERG) ...
