Complex Response to Periodic Inhibition in Simple and Detailed Neuronal Models

摘要

Constant current injection with superimposed periodic inhibition gives rise to phase locking as well as chaotic activity in rat neocortical neurons. Here we compare the behavior of a leaky integrate-and-fire neural model Which membrane properties influence the response to such stimuli. We Find that only the biophysical model with voltage-sensitive conductances Can produce chaotic behavior.
