Tonic inhibition of accumbal spiny neurons by extrasynaptic 4 GABAA receptors modulates the actions of psychostimulants [PDF]
, 2014 Within the nucleus accumbens (NAc), synaptic GABAA receptors (GABAARs) mediate phasic inhibition of medium spiny neurons (MSNs) and influence behavioral responses to cocaine.

Metabotropic Regulation of Extrasynaptic GABAA Receptors
Frontiers in Neural Circuits, 2013 A large body of work now shows the importance of GABAA receptor-mediated tonic inhibition in regulating CNS function. However, outside of pathological conditions, there is relatively little evidence that the magnitude of tonic inhibition is itself under ...

Pathophysiological power of improper tonic GABAA conductances in mature and immature models
Frontiers in Neural Circuits, 2013 High-affinity extrasynaptic gamma-aminobutyric acid A (GABAA) receptors are tonically activated by low and consistent levels of ambient GABA, mediating chronic inhibition against neuronal excitability (tonic inhibition) and the modulation of neural ...

Enhanced tonic GABAA inhibition in typical absence epilepsy [PDF]
Nature Medicine, 2009 The cellular mechanisms underlying typical absence seizures, which characterize various idiopathic generalized epilepsies, are not fully understood, but impaired gamma-aminobutyric acid (GABA)-ergic inhibition remains an attractive hypothesis. In contrast, we show here that extrasynaptic GABA(A) receptor-dependent 'tonic' inhibition is increased in ...

Tonic Inhibition of TRPV3 by Mg2+ in Mouse Epidermal Keratinocytes [PDF]
Journal of Investigative Dermatology, 2012 The transient receptor potential vanilloid 3 channel (TRPV3) is abundantly expressed in epidermal keratinocytes and has important roles in sensory biology and skin health. Mg(2+) deficiency causes skin disorders under certain pathological conditions such as type 2 diabetes mellitus.

Tonic and phasic nitric oxide signals in hippocampal long-term potentiation [PDF]
, 2006 Nitric oxide ( NO) participates in long-term potentiation (LTP) and other forms of synaptic plasticity in many different brain areas but where it comes from and how it acts remain controversial.

The general anaesthetic etomidate inhibits the excitability of mouse thalamocortical relay neurons by modulating multiple modes of GABAA receptor-mediated inhibition [PDF]
, 2014 Modulation of thalamocortical (TC) relay neuron function has been implicated in the sedative and hypnotic effects of general anaesthetics. Inhibition of TC neurons is mediated predominantly by a combination of phasic and tonic inhibition, together with a
