Emerging neurotrophic role of GABAB receptors in neuronal circuit development
The proper development of highly organized structures in the central nervous system is a complex process during which key events - neurogenesis, migration, growth, differentiation, and synaptogenesis - have to take place in an appropriate manner to create functional neuronal networks. It is now well established that GABA, the main inhibitory neurotransmitter in the adult mammalian brain, plays ...
متن کاملRole of the AMPA receptors of paragigantocellularis lateralis nucleus in the inflammatory pain modulation in male rat
Introduction: The 17β-estradiol acts as a neurosteroid in the brain and modulates nociception by binding to the estrogen receptors and also by allosteric interaction with other membrane-bound receptors like glutamate receptors. Paragigantocellularis lateralis nucleus (LPGi) is one of the important brain regions implicated in the pain modulation. So, this study was designed to evaluate the ...
متن کاملRegulating hippocampal hyperexcitability through GABAB Receptors
Abstract Disturbances of GABAergic inhibition are a major cause of epileptic seizures. GABA exerts its actions via ionotropic GABAA receptors and metabotropic G protein-coupled GABAB receptors. Malfunction of GABAA inhibition has long been recognized in seizure genesis but the role of GABAB receptors in controlling seizure activity is still not well understood. Here, we examined the anticonvuls...
متن کاملSuprachiasmatic modulation of noradrenaline release in the ventrolateral preoptic nucleus.
As the major brain circadian pacemaker, the suprachiasmatic nucleus (SCN) is known to influence the timing of sleep and waking. We thus investigated here the effect of SCN stimulation on neurons of the ventrolateral preoptic nucleus (VLPO) thought to be involved in promoting sleep. Using an acute in vitro preparation of the rat anterior hypothalamus/preoptic area, we found that whereas single-p...
متن کاملGABAB receptor modulation of rapid inhibitory and excitatory neurotransmission from subfornical organ and other afferents to median preoptic nucleus neurons.
Cardiovascular and behavioral responses to circulating angiotensin require intact connectivity along the upper lamina terminalis joining the subfornical organ (SFO) with the median preoptic nucleus (MnPO). Whole cell patch-clamp recordings in sagittal rat brain slice preparations revealed that 28/40 MnPO neurons responded to electrical stimulation of SFO efferents with bicuculline-sensitive GAB...
