Central injection of substance P elicits grooming behavior and motor inhibition in mice
(Elsevier, 1979-04)
Substance P undecapeptide (SP) was injected into the lateral ventricles of adult male Swiss-Webster mice. Two behaviors were observed after peptide. SP increased grooming in a naloxone non-reversible manner and reduced ...
Progesterone: Examination of its postulated inhibitory actions on lordosis during the rat estrous cycle
(Elsevier, 1976-09)
Three experiments tested whether the inhibitory effects of progesterone could be of physiological significance in regulating the duration of behavioral estrus in female rats. In animals displaying 5 day estrous cycles, a ...
On drinkometers: Problems and an inexpensive photocell solution
(Elsevier, 1971-12)
Electronic contact switches may interfere with measurements of taste discrimination and also the ability to utilize physiological recording or stimulation techniques simultaneously. An inexpensive and simply constructed ...
The effects of thyroidectomy on the wheel running activity of female rats
(Elsevier, 1970-11)
The wheel running activity of female rats was observed prior to and following thyroidectomy. Thyroidectomy significantly reduced overall activity and increased the interval between activity peaks; thyroid feeding corrected ...
The role of the optic tectum in various visually mediated behaviors of goldfish
(Elsevier, 1977-06-17)
Five visually mediated behaviors were assessed following ablation of one or both lobes of the optic tectum in goldfish. Three of the behaviors disappeared following tectal ablations; optomotor response (swimming with the ...
Effects of previous curare-immobilization on Pavlovian conditioned heart decelerations in the curarized rat
(Elsevier, 1975-03)
Recent evidence indicates that mechanisms other than the vagal-blocking properties of d-tubocurarine chloride (dTC) or inadequate respiration may account for the reports of invariant heart rate (HR) in curarized rats. Two ...
Hypophysectomy and the structure of exploratory behavior in the rat
(Elsevier, 1979-10)
Chronically maintained hypophysectomized or sham-operated adult male Sprague/2-Dawley rats were exposed to a novel environment and their activity patterns were recorded for 4 hr. A comparison of behavior across groups ...
A comparison of enzyme patterns in the granular and molecular layers of the rabbit cerebellar cortex
(Elsevier, 1972-07-13)
1. (1) Homogenates of hand-dissected granular and molecular layers of the cerebellar cortex of the rabbit were prepared and the following enzymes assayed: acetylcholinesterase, succinate-INT-reductase, particulate ...
Retinofugal pathways in fetal and adult spiny dogfish, Squalus acanthias
(Elsevier, 1979-02-23)
Retinofugal pathways in fetal and adult spiny dogfish were determined by intraocular injection of [3H]proline for autoradiography. Distribution and termination of the primary retinal efferents were identical in pups and ...
Differences in developing the lever-pressing behavior in two strains of rats
(Elsevier, 1975-06)
Learning to lever-press for food in rats may be experimentally analyzed according to (a) association of lever-pressing with food reinforcement; (b) development of the behavior of lever-pressing. The latter was studied in ...
