tetrodotoxin TTX
Potent neurotoxin that selectively blocks voltage-gated sodium channels, preventing action potential generation.
ectopic spike
An action potential that originates from an abnormal location along the axon rather than the normal initiation site.
interictal spike
Brief epileptiform discharges recorded between seizures on EEG, serving as markers of epileptic brain tissue.
spike train
A sequence of action potentials recorded from a single neuron over time, appearing as discrete electrical events.
spike-timing-dependent plasticity
Form of synaptic plasticity where the relative timing of pre- and postsynaptic spikes determines synaptic strength chang...
spike-triggered average
Statistical method to determine the stimulus features that precede action potentials.
