Genetic and environmental influences on reactive and spontaneous locomotor activities in rats
Experientia, 1991Paired groups of rats (derived from divergent, selective breeding or living in divergent environmental conditions) were compared with regard to locomotor activities. Intrapair differences were found to vary non-systematically, depending upon whether the rats were initially exposed to a test-environment with or without a slight environmental ...

Effects of 5-HT serotonin on spontaneous locomotor activity of eels
Comparative Biochemistry and Physiology Part C: Comparative Pharmacology, 1984The swimming activity of eels maintained in tap water at 8-12 degrees C is significantly decreased after i.p. para-chlorophenylalanine (pCPA) administration at dose of 200 mg/kg (p less than 0.005 to respective control value). 5-Hydroxytryptophan (5-HTP) restored transitory swimming activity of eels.

The suppression of mouse spontaneous locomotor activity by the ingestion of deuterium oxide
Experientia, 1976The spontaneous locomotor activity of the laboratory mouse is significantly depressed by the ingestion of deuterium oxide. The response, which is reversible, is a retilinear one with up to 70% reduction in activity with the administration of 25% heavy water.

A method for monitoring spontaneous locomotor activity and resting behavior in fishes
Physiology & Behavior, 1976Abstract A method is described for quantitative temporally definable measurements of fishes using the black bullhead ( Ictalurus melas ). The system is based on the photosensor principle and it designed to scan the position of a single fish at a time in reference to an opaque mark affixed to the side of a circular activity channel.

Decreased spontaneous locomotor activity in the rat induced by hypothalamic lesions
American Journal of Physiology-Legacy Content, 1962A permanent decrease in spontaneous locomotor activity of the rat can be produced by destruction of either of two specific regions in the ventral hypothalamus at the level of the tuber cinereum. One is a lateral region which lies between the fornix and cerebral peduncle and extends from the level of the fornix downward to the base of the brain.

Effects of repeated administration of chlordiazepoxide on spontaneous locomotor activity in mice
Psychopharmacology, 1979Spontaneous locomotor activity has been studied in mice treated with single or repeated doses (five daily injections) of chlordiazepoxide. The repeated administration enhanced the stimulatory action of the lower doses of the drug, while the depressant effect of the higher doses was reduced.

Sex differences in spontaneous locomotor activity and rotational behavior in meadow voles
Physiology & Behavior, 1998Sex differences in rotational behavior have been most clearly established in laboratory rats with females exhibiting a turning bias. Here, using an automated open-field apparatus, locomotor activity and spontaneous rotational behavior were examined in diurnally crepuscularly active reproductive male and female meadow voles (Microtus pennsylvanicus ...

Inhibitory and excitatory effects of adenosine antagonists on spontaneous locomotor activity in mice
Life Sciences, 1997The behavioral effect of the adenosine antagonists CPT, PACPX, DPCPX and PD 115,199 on spontaneous locomotor activity was investigated in mice after parenteral administration. CPT, PACPX and PD 115,199 affected locomotor activity in a biphasic way. Doses in the nanomolar/kg range significantly reduced locomotion (PACPX> or =PD 115,199>>CPT).

Repeatability of thermal reaction norms for spontaneous locomotor activity in juvenile newts
Journal of Thermal Biology, 2019Locomotor activity is a major attribute of animals. Although this trait determines important ecological processes, such as dispersal and species interactions, the sources of its variation are not fully understood. We examined the influence of body temperature (13, 18, 23, and 28 °C) and individual identity on spontaneous locomotor activity in juvenile ...

Olfactory bulb removal results in elevated spontaneous locomotor activity in mice
Physiology & Behavior, 1976Abstract Bilateral removal of the olfactory bulbs of female Swiss-Webster mice resulted in a striking increase in locomotor activity which remained evident even 2 1 2 months after surgery. The administration of d-amphetamine sulfate (1, 2, and 4 mg/kg) resulted in a dose dependent increase in locomotor activity but bilateral bulbectomy did ...
