spike sorting
Computational process of identifying and classifying action potentials from individual neurons in extracellular recordings.
Full Definition
Spike sorting is a critical preprocessing step in neurophysiology that involves detecting action potentials (spikes) in extracellular neural recordings and attributing them to individual neurons. This process typically involves spike detection, feature extraction, and clustering algorithms to separate spikes from different neurons based on their waveform characteristics. Accurate spike sorting is essential for single-cell analysis and understanding neural coding mechanisms.
