The anticonvulsant activity of diazepam and phenobarbital may be mediated in part by enhancement of inhibition involving γ‐aminobutyric acid (GABA). While both diazepam and phenobarbital increase GABA receptor chloride current, they may have different mechanisms of action, since they bind to different sites on the GABA receptor—chloride channel complex. We used the patch clamp technique to compare the effects of diazepam and phenobarbital on single GABA receptor currents. Outside‐out patches… 
Context Dependent Benzodiazepine Modulation of GABAA Receptor Opening Frequency
TLDR
Not only can multiple kinetic mechanisms alter channel opening frequency, but a single mechanism – increased affinity – impacts opening frequency differently under different contexts of GABAA receptor activation.
Hippocampal GABAAchannel conductance increased by diazepam
TLDR
It is shown that the benzodiazepine diazepam can also increase the conductance of GABAAchannels activated by low concentrations of GABA in rat cultured hippocampal neurons, which may be an important way in which these drugs depress excitation in the central nervous system.
Benzodiazepine and beta‐carboline regulation of single GABAA receptor channels of mouse spinal neurones in culture.
TLDR
It is proposed that DZ and DMCM alter GABAA receptor current by acting reciprocally to increase or decrease only, respectively, the apparent agonist association rate at the first of two proposed GABA binding steps without altering channel gating.
Terbium modulation of single gamma-aminobutyric acid-activated chloride channels in rat dorsal root ganglion neurons
TLDR
It is suggested that Tb3+ binds to an allosteric site on the GABAA receptor-channel complex to increase the apparent mean open time of the channel by increasing the affinity of GABA for the GABA binding site, and/or by shifting the distribution toward the open states so that the frequency of occurrence of longer open states is stabilized.
Mechanism of action of benzodiazepines on GABAA receptors
TLDR
A mechanism in which DZP increases the apparent affinity of the receptor, not by altering the affinity of a closed state, but rather by shifting the equilibrium towards the high‐affinity open state is supported.
The diversity of GABAA receptors
TLDR
The pharmacology of putative receptor isoforms is summarized and the characteristics of functional channels are emphasized to further the understanding of GABA-related disorders and of the complex interaction of excitatory and inhibitory mechanisms in neuronal processing.

TLDR
The drugs each increase the response to GABA but do not act on channel kinetics in the same manner, so changes in the kinetics of GABA-activated ion channels can quantitatively account for the potentiation of GABA responses observed with the drugs.

TLDR
The results suggest that (1) the synaptic events are GABA-mediated and (2) the enhancement of these events by barbiturate is due to the postsynaptic action of the drug.
The GABA postsynaptic membrane receptor-ionophore complex
TLDR
Available evidence suggests that the GABA receptor-ionophore system mediates many of the actions of numerous excitatory and depressant drugs showing a variety of pharmacological effects.

TLDR
Evidence supports the model for a complex containing receptor sites for GABA, benzodiazepines, and picrotoxininl barbiturates, as well as the chloride ionophore, and thus the relevance of GABA to the actions of the other drugs.
Activation of multiple-conductance state chloride channels in spinal neurones by glycine and GABA
TLDR
It is reported that in small membrane patches, isolated from the soma of spinal neurones, both receptor channels display several (multiple) conductance states, and one class of multistate Cl−channel is coupled to either GABA or glycine receptors.
Anticonvulsant and anesthetic barbiturates
TLDR
Modulation of synaptic events mediated by GABA and GLU might contribute to barbiturate anticonvulsant activity; and direct GABA-mimetic inhibition, combined with similar modulation of synaptic transmission, might underlie barbitural anesthesia.
Mechanism of anion permeation through channels gated by glycine and gamma‐aminobutyric acid in mouse cultured spinal neurones.
TLDR
The ion‐selective and ion transport properties of glycine receptor and gamma‐aminobutyric acid receptor channels in the soma membrane of mouse spinal cord neurones were investigated using the whole‐cell, cell‐attached and outside‐out patch versions of the patch‐clamp technique, indicating that GlyR and GABAR channels are multi‐conductance‐state channels.
Fast events in single‐channel currents activated by acetylcholine and its analogues at the frog muscle end‐plate.
TLDR
The fine structure of ion‐channel activations by junctional nicotinic receptors in adult frog muscle fibres has been investigated and the component of brief openings behaves, at low concentrations, as though it originates from openings of singly occupied channels.
Mouse spinal cord in cell culture. III. Neuronal chemosensitivity and its relationship to synaptic activity.
TLDR
Mouse spinal cord (SC) cells in dissociated cell cultures showed strong electrophysiologic responses to glutamate, gamma-aminobutyric acid (GABA), and glycine when these were iontophoretically applied to the neurons, indicating different ionic mechanisms for the glutamate response and the EPSP.
