title: Release of neurosecretory protein from insect neurohaemal tissue following electrical stimulation.
abstract: A protein, located within the protocerebral neurosecretory system of locusts, is released from the storage lobes of the corpora cardiaca following the propagation of a compound action potential to the storage lobe via the nervus corpus cardiacum I. Release depends upon the entry of extracellular calcium during depolarization. The data presented here indicate that a protein, similar to the neurophysins of vertebrates, is released from neurohaemal tissue of locusts following stimuli which are known to favour hormone release.
