Abstract
The complex processing and integration of signals observed in
neurons are facilitated by the diverse range of gating properties
of the ion channels in this cell type, particularly the voltage-
gated K+ channels (KV). A distinctive combination of K+
channels endows neurons with a broad repertoire of excitable
properties and allows each neuron to respond in a specific
manner to a given input at a given time. The properties of
many K+ channels can be modulated by second messenger
pathways activated by neurotransmitters and other stimuli.
K+ channels are among the most frequent targets of the actions
of several signalling systems.
