SIB-1765F ([+/-]-5-ethynyl-3-(1-methyl-2-pyrrolidinyl)pyridine fumarate) is a novel nicotinic acetylcholine receptor (NAChR) agonist displaying a different in vitro pharmacological profile than nicotine and epibatidine, suggestive of NAChR subtype selectivity. Our study describes the effects of SIB-1765F on locomotor activity in rats, which were compared to those observed for nicotine and epiba...

suppression of akt (protein kinase b) has been implicated in schizophrenia, the effect which has been documented to be reversed by tyrosine phosphatase inhibition. t hus, present study has been designed to study the effect of sodium orthovanadate, a tyrosine phosphatase inhibitor, on protracted methionine administration induced schizophrenia like behavior in rats.   schizophrenia like behavior ...

Although locomotor activity is involved in almost all behavioral traits, there is a lack of knowledge on what factors affect it. This study examined the effects of sex–ratio and density on the circadian rhythm of locomotor activity of adult Musca domestica L. (Diptera: Muscidae) using an infra–red light system. Sex–ratio significantly affected locomotor activity, increasing with the percentage ...

Stimultaneous determination of the circadian rhythms of locomotor activity and body temperature was carried out in the rat. Deep body temperature was monitored continuously using a telemetric device. The circadian rhythm of locomotor activity was characterized by clustering of several bursts of activity during the dark period. The circadian rhythm of body temperature was also characterized by b...

The contribution of left-right reciprocal coupling between spinal locomotor networks to the generation of locomotor activity was tested in adult lampreys. Muscle recordings were made from normal animals as well as from experimental animals with rostral midline (ML) spinal lesions (~13%→35% body length, BL), before and after spinal transections (T) at 35% BL. Importantly, in the present study ac...

the mesolimbic dopamine (da) system contains both d1-like and d2-like receptors, has been connected to control of locomotor behavior. an apparent role for d1 and d2 receptors throughout the mesolimbic system in the alteration of locomotor behavior has been demonstrated in pharmacological studies. the nucleus accumbens (nac) is comprised of a core and a shell subregion, which is a component of t...

The motor programme executed by the spinal cord to generate locomotion involves glutamate-mediated excitatory synaptic transmission. Using the neonatal rat spinal cord as an in vitro model in which the locomotor pattern was evoked by 5-hydroxytryptamine (5-HT), we investigated the role of N-methyl-D-aspartate (NMDA) and non-NMDA glutamate receptors in the generation of locomotor patterns record...

Background. the basal ganglia’s circuit dysfunction has a major role in a range of movement disorders. Some evidence has shown that exercise can improve performance, especially locomotor activity after brain injuries. There was currently insufficient information to define the impacts of intensity, duration, and frequency of different exercises. Objectives. in this study, we examine the r...
