The aim of the study was to determine whether betaxolol is a neuroprotective agent and can therefore slow down the changes seen in the retina following ischaemia/reperfusion. Ischaemia was induced in one rat eye by raising the intraocular pressure fo

The role of histamine in mediating restraint stress-induced alterations in dopaminergic neuronal activity and alpha-melanocyte-stimulating hormone (alpha MSH) secretion was evaluated in male rats. Dopaminergic neuronal activity was estimated by measu

In vivo voltammetry at electrochemically pretreated carbon fibre electrodes was used to investigate the effect of intracerebroventricular (i.c.v.) administration of N-methyl-D-aspartic acid (NMDA) on neuronal activity in rat nucleus accumbens. Infusi

In this study we have used whole-cell, voltage-clamp procedures to determine the effects of angiotensin II (AII) on net outward current (I(no)) in neurons co-cultured from the hypothalamus and brainstem of 1-day-old rats. Ino is the sum of all inward

A large number of estrogen-sensitive neurons in rat hypothalamus use gamma-aminobutyric acid (GABA) as a neurotransmitter. As estrogens influence the size of the sexually dimorphic nucleus (SDN) of the preoptic area it was tested whether perinatal tr

Among magnocellular neurosecretory neurons (MNCs), the frequency of dye coupling, and thus also of electrotonic coupling, is reduced in male rats following castration. Testosterone replacement prevented this reduction suggesting a modulatory role for

These studies examined the effects of cocaine on thalamic neurons that respond maximally either to noxious or to innocuous somatic stimulation. Cocaine attenuated high intensity electrically-evoked nociceptive responses of all 25 units studied in the

Systemic administration of cholecystokinin (CCK) decreases gastric motility and stimulates pituitary secretion of oxytocin (OT). Although peripheral OT does not affect gastric function, increasing evidence suggests that central OT secretion acting wi

The effects of psychological stress on catecholamine and indoleamine metabolism were examined in various brain regions of rats. Psychologically stressed rats were exposed to emotional responses of foot-shocked rats, but were themselves prevented from

We have previously extracted a serotonin (5-HT) neurotrophic supernatant from the 5,7-DHT lesioned hippocampus. The current study shows that a new 5-HT neurotrophic signal was monitored in the striatum and nigra after DA-denervation. Such a signal ma
