Nutritional status and spontaneous locomotor activity in the rat.
Indian journal of physiology and pharmacology, 1991A considerable amount of energy may be saved by lowering the spontaneous locomotor activity when energy intakes are reduced. The results of the present study in rats undernourished for a period of 21 or 60 days and subsequently fed ad libitum diet did not show any differences in activity when compared to their respective control groups, either during ...

Locomotor activity, auditory startle and shock thresholds in spontaneously hypertensive rats
Physiology & Behavior, 1983A group of SHRs and a group of WKY normotensive controls were compared sequentially on open-field behavior, Y-maze activity, responsiveness and habituation of the auditory startle response, and shock thresholds. In the open field and Y maze the SHRs were more active than the WKYs, but the locomotor activity of the SHRs decreased more within sessions ...

Abstract In an effort to discover if various classes of drugs could be differentiated on the basis of their ability to inhibit spontaneous and methamphetamine-induced locomotor activity, a series of drugs with a variety of pharmacological effects was tested for activity as inhibitors of spontaneous and methamphetamine-induced locomotor activity in ...

Glutamate antagonists have different effects on spontaneous locomotor activity in rats
Pharmacology Biochemistry and Behavior, 1994Locomotor activity, ataxia, and stereotypy were assessed in the open field after administration of NMDA and AMPA antagonists acting by different mechanisms. The interaction with glutamatergic receptors was confirmed in the binding assay. (+)MK-801 and phencyclidine (PCP) produced similar changes in horizontal activity, i.e., a strong increase from the ...

Chronotype and stability of spontaneous locomotor activity rhythm in BMAL1-deficient mice
Chronobiology International, 2014Behavior, physiological functions and cognitive performance change over the time of the day. These daily rhythms are either externally driven by rhythmic environmental cues such as the light/dark cycle (masking) or controlled by an internal circadian clock, the suprachiasmatic nucleus (SCN), which can be entrained to the light/dark cycle.

Abstract Locomotor activity patterns of intact flies under various feeding and deprivation schedules were studied with a tilting-type actograph and suitable recording apparatus. Under conditions of constant darkness, adults of P. regina exhibit well-marked circadian rhythms in locomotor activity.

Interneurones of the lumbar cord related to spontaneous locomotor activity in the rabbit
Experimental Brain Research, 1991In decorticate, unanaesthetized and curarized rabbit preparations displaying spontaneous fictive locomotor sequences, the firing pattern of neurones was recorded extracellularly in the L6-S1 spinal cord. These neurones, located in the intermediate part of the cord, were not invaded by antidromic stimulation of the hindlimb muscle nerves and thus were ...

Abstract Methionine-enkephalin (MEK), a postulated endogenous ligand for the opiate receptors, when administered intracerebroventricularly (ICV) in a dose of 1.75 μmoles/kg) of morphine sulfate had no effect on motor activity. Higher doses (7.0 μmoles/kg) of both MEK and morphine produced profound depression in motor activity; the decrease was ...

Digital Outcome Measures for Gait and Spontaneous Locomotor Activity in Dystrophic Dogs
Digital outcome measures utilizing digital devices and instruments are highly effective in capturing significant changes quantitatively in clinical trials of patients with Duchenne muscular dystrophy. A dystrophic model of beagle dogs, known as canine X-linked muscular dystrophy in Japan (CXMDJ), shows the symptoms of muscle weakness and has been ...Mutsuki, Kuraoka +7 more
