Abstract:
Neurons possess multiple types of voltage-dependent calcium channels. These channels are classified as either low-voltage-activated (LVA/T-type) or high-voltage-activated (HVA) consisting of L, N, P, Q and R subtypes. T-type Ca channels can be opened by small depolarization that are under the threshold for action potential generation. These T-type Ca channels may be involved in the sub threshold depolarizations that underlies neuronal bursting activities in neurons. Such burst firing might originate in the postsynaptic membrane of the neuronal dendrites.

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...
