Post-spike hyperpolarization participates in the formation of auditory behavior-related response patterns of inferior collicular neurons in Hipposideros pratti

Highlights • Stimulated with CF–FM sounds, the bat IC neurons discharge as SO or DO responders. • 65.1% of the SO neurons have long-duration post-spike hyperpolarizations. • 75% of the DO neurons have no or inconspicuous post-spike hyperpolarizations. • Post-spike hyperpolarizations are thought to s...

Description
Summary:Highlights • Stimulated with CF–FM sounds, the bat IC neurons discharge as SO or DO responders. • 65.1% of the SO neurons have long-duration post-spike hyperpolarizations. • 75% of the DO neurons have no or inconspicuous post-spike hyperpolarizations. • Post-spike hyperpolarizations are thought to shape the SO and DO neurons. • The biological relevance of these findings in relation to bat hunting is discussed.
