The first identified neuropeptide in the insect order Megaloptera: a novel member of the adipokinetic hormone family in the alderfly Sialis lutaria.

abstract：:Exposure of guinea pigs to the elevated plus maze (X-maze), an animal model of anxiety, causes an increase of extracellular serotonin (5-HT) in the lateral prefrontal cortex monitored by microdialysis. The neuropeptide cholecystokinin (CCK) plays a role in the modulation of anxiety. To compare the roles of CCK recepto...
