Abstract:
Ion channels are a family of protein molecules that mediate the electrical activities, including synaptic transmission, of the nervous system. Recent studies revealed that genetic mutations are associated with various neurological disorders. Although identification of the genetic defects is certainly a big step towards elucidation of pathophysiology and development of therapeutic strategies, it is not always easy to correlate the genetic abnormalities with the neurological symptoms. Recently, we have analyzed the pathophysiological mechanism of cerebellar ataxia and absence epilepsy in calcium channel mutant mice. The results demonstrate diversity of the cellular and network changes caused by the genetic defects. Understanding the underlying mechanism of the diverse changes would contribute to better understanding of human neurological diseases.

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...
