Threshold in neural models

Participant : Arnaud Tonnelier.

We studied the threshold for spike initiation in two-dimensionnal neural models. A threshold criterion that depends on both membrane voltage and recovery (or adaptation) variable is proposed. Our approach provides a simple and unified framework that can account for adapting threshold, threshold variability, dynamic threshold, inhibition-induced spike and postinhibitory facilitation. Implications on neural modeling and on neural dynamics are discussed.
