What happens when animals are startled?

November 29, 2019

New paper from the lab that shows when flies are startled, the response to pause, which lasts only a few seconds, is mediated by a set of serotonergic neurons in the ventral nerve cord (VNC). Serotonergic release also serves as a constitutive break on walking speed and when this break is not functional, flies walk faster than normal, in a wide variety of situations. For example, when flies  are hungry they walk faster than normal, but they walk even faster when the serotonergic break is not functional.
