This suggests the occurrence of abnormal hypersynchrony in the thalamocortical system. Within the thalamus, the efficacy of inhibitory synapses between thalamic reticular (RE) neurons is selectively compromised, …

Webshunting inhibition. But contrary to its divisive effect on depolar-ization, shunting inhibition on its own fails to divisively modulate firing rate, apparently upsetting a critical tenet of neural models that use shunting inhibition to achieve gain control. Using a biophysically realistic neuron model, we show that divisive mod- WebFeb 4, 2003 · Effect of shunting inhibition on firing rate depends on stimulus conditions.

WebSep 14, 2004 · The shunting effect is powerful when the inhibitory synapses are colocalized with the excitation, as indicated by a strongly depressed somatic response (left blue trace). When the inhibition is delivered to a different branch, the somatic response is only mildly suppressed (compare right red and blue traces). WebJul 9, 2014 · Gamma oscillations are a prominent phenomenon related to a number of brain functions. Data show that individual pyramidal neurons can fire at rate below gamma with the population showing clear gamma oscillations and synchrony. In one kind of idealized model of such weak gamma, pyramidal neurons fire in clusters. Here we provide a theory … Shunting inhibition, also known as divisive inhibition, is a form of postsynaptic potential inhibition that can be represented mathematically as reducing the excitatory potential by division, rather than linear subtraction. The term "shunting" is used because of the synaptic conductance short-circuit currents that … See more Shunting inhibition was discovered by Fatt and Katz in 1953.
