WebWhen an allosteric inhibitor binds to an enzyme, all active sites on the protein subunits are changed slightly so that they work less well. There are also allosteric activators. Some allosteric activators bind to locations on an enzyme other than the active site, causing an increase in the function of the active site.

Lastly, we show the positive allosteric modulator diazepam enhanced GABA-A currents on dopaminergic axons and directly inhibited release, but also likely acts by reducing excitation from cholinergic interneurons.

WebShunting inhibition should therefore not be effective on spines, but it could be significantly more effective on the dendritic shaft at the base of the spine. In contrast to shunting … WebMar 4, 2016 · Shunting inhibition is particularly effective in reducing the effect of more distally located excitatory inputs. This is sometimes referred to as ‘on-the-path’ inhibition. …

WebMay 8, 2003 · Shunting inhibition is not thought to control gain since it shifts input-output relationships during tonic excitation rather than changing their slope. Here we show that tonic inhibition reduces the gain and shifts the offset of cerebellar granule cell input-output relationships during frequency-dependent excitation with synaptic conductance ...
