Figure 4From: Ghrelin accelerates synapse formation and activity development in cultured cortical networksExtensive activities recording from ghr culture. (A) Raster plot of the neuronal activity recorded from ghrelin treated culture at 4 DIV (368 spikes per minute). (B) Raster plot of the activity recorded for 20Â min from ghr culture at age 88 DIV. The activity level is still high (6652 spikes per minute).Back to article page
