Rapid cold hardening increases axonal Na+/K+-ATPase activity and enhances performance of a visual motion detection circuit in Locusta migratoria

RM Robertson, CD Moyes - Journal of Experimental Biology, 2022 - journals.biologists.com
Rapid cold hardening (RCH) is a type of phenotypic plasticity that delays the occurrence of
chill coma in insects. Chill coma is mediated by a spreading depolarization of neurons and …
