Threatened animals respond with appropriate defensive behaviors to survive. It has been accepted that midbrain periaqueductal gray (PAG) plays an essential role in the circuitry system and organizes behavioral responses. However, correlation of different PAG subregions expression remain largely unexplored. Here, we designed manufactured a microelectrode array (MEA) simultaneously detect activities dPAG vPAG neurons freely behaving rats. To improve detection performance MEAs, PtNP/PEDOT:PSS...
