Abstract:
Neurons express a large number of different voltage-gated potassium (Kv) channels with distinct biophysical and biochemical properties. Possibly, this diversity reflects the need to regulate and fine-tune neuronal excitability at various levels of complexity in space and time. In this context, Kv channels operating in the subthreshold range of action- potential firing are of particular interest. It is likely that these Kv channels play a prominent role in both propagating and integrating dendritic signaling, as well as axonal action-potential firing and propagation.

The Role of Ion Channels in Neuronal Computation
Sometimes a single EPSP is strong enough to induce an action potential in the postsynaptic neuron. However, multiple presynaptic inputs must often create EPSPs around the same time for the postsynaptic neuron to be sufficiently depolarized to fire an action potential.
Voltage-gated Ion Channels
Generally, all voltage-gated ion channels have a 'voltage-sensing domain' that spans the lipid bilayer. The charged residues in the sensor move in response to the membrane potential changes that open the channel allowing ions movement. There are several types of...
