Beschreibung:
Populations of cortical neurons in the fluctuation-driven regime exhibit an ultrafast population response. Some theoretical studies suggest that passive, morphological features of the axon and dendrites determine the population response, while others emphasize the importance of ion channel properties at the neuron’s axon initial segment (AIS), the site of action potential initiation. One hypothesis posits that the electrotonic separation of the site of action potential initiation from the soma is a sufficient condition for the emergence of the ultrafast population response. Another hypothes...
