Low threshold spikes

Low threshold spikes

Low-threshold spikes (LTS) refere to action potentials generated from a membrane potential negative to that for sodium spike threshold (firing level). These LTS's were originally observed in inferior olive neurons (Llinas and Yarom 1981) and then in thalamic neurons (Llinas and Janhsen 1982). They are supported by calcium currents following the activation of T-type calcium channel.
