KV1 channel governs cerebellar output to thalamus (Ovsepian et al. 2013)
||The output of the cerebellum to the motor axis of the central nervous system is
orchestrated mainly by synaptic inputs and intrinsic pacemaker activity of deep cerebellar nuclear
(DCN) projection neurons. Herein, we demonstrate that the soma of these cells is enriched with
KV1 channels produced by mandatory multi-merization of KV1.1, 1.2 alpha andKV beta2 subunits. Being
constitutively active, the K+ current (IKV1) mediated by these channels stabilizes the rate and
regulates the temporal precision of self-sustained firing of these neurons.
Through the use of multi-compartmental modelling and ... the physiological significance of the described functions for processing
and communication of information from the lateral DCN to thalamic relay nuclei is established.
STD-dependent and independent encoding of Input irregularity as spike rate (Luthman et al. 2011)
||"... We use a
conductance-based model of a CN neuron to study the
effect of the regularity of Purkinje cell spiking on CN
We find that increasing the irregularity of
Purkinje cell activity accelerates the CN neuron spike rate
and that the mechanism of this recoding of input irregularity
as output spike rate depends on the number of Purkinje
cells converging onto a CN neuron.
