Voltage-activated sodium channels amplify inhibition in neocortical pyramidal neurons

Stuart, Gregory J


Inhibitory postsynaptic potentials (IPSPs) in neocortical pyramidal neurons are increased in duration and amplitude at depolarized membrane potentials. This effect was not due to changes in the time course of the underlying synaptic current. The role of postsynaptic voltage-activated channels was investigated by mimicking the voltage change that occurs during an IPSP with current injections. The peak and integral of these 'simulated' IPSPs increased during depolarization of the membrane...[Show more]
