Abstract:
T-type, or low-voltage-activated (LVA), tiny and transient Ca2+ currents pare more and more recognised as universal players in a plethora of cell functions and are also more and more connected to several diseases. This short introduction reviews the discovery of T-type Ca2+ channels, describes its basic properties and sketches its cloning and physiological impact. Finally, an overview is given how research on T-type Ca2+ channels has developed in the last years and in which topics it is branching out, a process, which is still ongoing.

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...
