Sleep, epilepsy and thalamic reticular inhibitory neurons
Trends in Neurosciences, 2005Thalamic reticular neurons release the potent inhibitory neurotransmitter GABA and their main targets are thalamocortical neurons in the dorsal thalamus. This article focuses on two topics: (i) the role of thalamic reticular neurons in the initiation of spindles, a hallmark oscillation during early sleep stages; and (ii) the reticular-induced ...

Inhibitory neurons: VIP neurons expect rewards
Current Biology, 2023Inhibitory neurons which express vasoactive intestinal polypeptide, VIPs, are a small subset of the mammalian cortex but in importance live up to their acronym. New research shows that these critical control knobs of cortical activity are specifically activated by actions taken when rewards are anticipated rather than consummated.

NMDA receptor function in inhibitory neurons
Neuropharmacology, 2021N-methyl-d-aspartate receptors (NMDARs) are present in the majority of brain circuits and play a key role in synaptic information transfer and synaptic plasticity. A key element of many brain circuits are inhibitory GABAergic interneurons that in themselves show diverse and cell-type-specific NMDAR expression and function.

Cortical inhibitory neurons and schizophrenia
Nature Reviews Neuroscience, 2005Impairments in certain cognitive functions, such as working memory, are core features of schizophrenia. Convergent findings indicate that a deficiency in signalling through the TrkB neurotrophin receptor leads to reduced GABA (gamma-aminobutyric acid) synthesis in the parvalbumin-containing subpopulation of inhibitory GABA neurons in the dorsolateral ...

The inhibitory neuronal glycine receptor
BioEssays, 1994AbstractGlycine is a major inhibitory neurotransmitter in the spinal cord and in the brain stem, where it acts by activating a chloride conductance. The postsynaptic glycine receptor has been purified and contains two transmembrane subunits of 48 kDa (α) and 58 kDa (β), and a peripheral membrane protein of 93 kDa.

1. During direct and antidromic cortical stimulation a few neurons (3%) respond by a high-frequency discharge coinciding in time with the beginning of the inhibitory pause of the remaining cortical neurons. 2. The group of neurons thus distinguished is similar in its electrophysiological properties to Renshaw cells of the spinal cord.

Characteristics of cortical inhibitory neurons
Neurophysiology, 1975Spikes were recorded extracellularly and IPSPs intracellularly from auditory cortical neurons of cats immobilized with D-tubocurarine in response to stimulation of geniculo-cortical fibers. Fibers whose stimulation induces IPSPs in auditory cortical neurons mainly have low thresholds. When two stimuli, each of which separately evoked an IPSP of maximal

Discovered 30 years ago, axo-axonic or Chandelier cells are the most specific inhibitory neurotransmitter γ-aminobutyric acid-releasing (GABAergic) cell type known and are regularly used in textbooks to illustrate the strategic placement of inhibition on the axon. Szabadics et al.

Synaptic Integration in Cortical Inhibitory Neuron Dendrites
Neuroscience, 2018Cortical inhibitory interneurons have a wide range of important functions, including balancing network excitation, enhancing spike-time precision of principal neurons, and synchronizing neural activity within and across brain regions. All these functions critically depend on the integration of synaptic inputs in their dendrites.
