    Ghrelin is a neuropeptide regulating multiple physiological processes, including high brain functions such as learning and memory formation. However, the effect of ghrelin on network activity patterns and developments has not been studied yet. Therefore, we used dissociated cortical neurons plated on multi electrode arrays (MEAs)to investigate in vitro how acute and chronic exposure to ghrelin affects neuronal activiy. We found that ghrelin application has a strong stimulatory effect on neuronal activiy, and causes a switch from synchronous to more dispersed asynchronous network firing. When chronically applied, ghrelin leads to earlier generation of "mature" activity patterns, including neuronal bursts.
