spike train
A temporal sequence of action potentials recorded from a single neuron or electrode. The pattern and timing of spikes encode neural information.
Full Definition
A spike train represents the temporal sequence of action potentials (spikes) recorded from a single neuron or microelectrode over time. In neuroinformatics, spike trains are fundamental data structures for analyzing neural coding, synchronization, and information transmission. The interspike intervals, firing rates, and temporal patterns within spike trains reveal how neurons encode and process information. Analysis of spike trains involves statistical methods to decode neural signals and understand population dynamics in neural circuits.
Usage
Usage note: Distinguish from 'spike sorting' which refers to the computational process of separating individual neuron signals from multi-unit recordings.
