How does shunting inhibition work
WebShunting inhibition is theorized to be a type of gain control mechanism, regulating the responses of neurons. [5] [6] Simple inhibition such as hyperpolarization has a subtractive effect on the depolarization caused by concurrent excitation, whereas shunting inhibition can in some cases account for a divisive effect. [7] WebShunting inhibition reduced very substantially the firing frequency in the primary range without changing the slope of the current–frequency curves. The shift of the I–f curve was proportional to the conductance increase imposed by the dynamic clamp and depended on an intrinsic property of the motoneurone that we called the shunt potential.

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.

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. … WebNetworks of GABAergic neurons are key elements in the generation of γ oscillations in the brain. Computational studies suggested that the emergence of coherent oscillations requires hyperpolarizing inhibition. Here, we show that GABAA receptor-mediated inhibition in mature interneurons of the hippocampal dentate gyrus is shunting rather than …
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 ...
