Intrinsic Ionic Mechanisms Underlying Burst Firing in Spontaneously Active Dorsal Horn Parvalbumin Interneurons

Rian Fritz Jalandoni, Christopher Todrineau, Haoyi Qiu, Erik P. Cook, Arjun Krishnaswamy, Reza Sharif‐Naeini, Anmar Khadra

The paper develops a stochastic HH model to study intrinsic ionic mechanisms driving spontaneous firing in spPVINs, revealing how Ih and noise contribute to irregular bursting and circuit inhibition.
