Asynchronism in the neurogenesis of GABAergic and non-GABAergic neurons in the mouse hippocampus
Developmental Brain Research, 1986The time course of the neurogenesis of cells showing glutamic acid decarboxylase (GAD) immunoreactivity has been analyzed in the dorsal hippocampus and area dentata of the mouse. The quantitative data indicate that gamma-aminobutyric acid (GABA)ergic cells are generated prenatally, and that their peaks of neurogenesis occur before the peaks of ...

Mechanisms regulating GABAergic neuron development
Cellular and Molecular Life Sciences, 2013Neurons using gamma-aminobutyric acid (GABA) as their neurotransmitter are the main inhibitory neurons in the mature central nervous system (CNS) and show great variation in their form and function. GABAergic neurons are produced in all of the main domains of the CNS, where they develop from discrete regions of the neuroepithelium.

Effect of diazepam on gabaergic cuneate neurons
Neuropharmacology, 1979Abstract Diazepam may act as a γ-aminobutyric acid (GABA) agonist in the CNS, but the evidence is conflicting. This study done with iontophoresis demonstrated that diazepam inhibited the spontaneously firing neurons in the cuneate nucleus, also inhibited by GABA.

GABAergic neurons in rat hippocampal culture
Developmental Brain Research, 1986The experiments described here were designed to study biochemical and histological measures of gamma-aminobutyric acid (GABA) uptake and glutamic acid decarboxylase (GAD) in primary dissociated cell cultures prepared from 17-21-day fetal rat hippocampus.

Scientific American, 1988
One tends to think of the nervous system in terms of chains of excitatory signals that tell neurons to fire. The signals that say "Don't fire" also have a major role. Inhibitory signals damp overall neural activity and also fine-tune the responses of particular circuits. The primary carrier of these signals is the inhibitory transmitter known as GABA.

Behavioral consequences of GABAergic neuronal diversity
Current Opinion in Neurobiology, 2014The majority of cellular diversity in the hippocampus and neocortex derives from a relatively small population of local inhibitory interneurons. Recent technological advances have facilitated the recording and manipulation of defined inhibitory cell classes in awake rodents, revealing new and surprising roles for these cells in local circuit function ...

Development of the GABAergic and glutamatergic neurons of the lateral hypothalamus
Journal of Chemical Neuroanatomy, 2021In the last few years we assist to an unexpected deluge of genomic data on hypothalamic development and structure. Perhaps most surprisingly, the Lateral Zone has received much attention too. The new information focuses first of all on transcriptional heterogeneity.

Gabaergic transmission by POA neurons to orexin neurons
Sleep Medicine, 2013Introduction Populations of neurons in the hypothalamic preoptic area (POA) fire rapidly during sleep, exhibiting sleep/waking state-dependent firing patterns that are the reciprocal of those observed in the arousal system. The majority of these preoptic_gsleep-active_h neurons contain the inhibitory neurotransmitter GABA. These neurons are thought to

GABAergic neurons in the entorhinal cortex project to the hippocampus
Brain Research, 1989Among the entorhinal neurons that give rise to the perforant path, a small population is sparsely spinous and displays either a multipolar or a horizontal-bipolar dendritic tree. By application of post-embedding immunocytochemistry to neurons of these types with previously identified projections to the hippocampus we found immunoreactivity for gamma ...

GABAergic septohippocampal neurons contain parvalbumin
Brain Research, 1989Septal axons were visualized in the hippocampus by anterograde transport of Phaseolus vulgaris leucoagglutinin (PHAL) injected into the medial septal region, which contains large numbers of parvalbumin (PV)-immunoreactive somata. A proportion of the PHAL-labelled afferents in the hippocampus were shown to be immunoreactive for PV by immunostaining ...
