Long-term expression of two interacting motor pattern-generating networks in the stomatogastric system of freely behaving lobster.

abstract：:The induction of NMDA-receptor-dependent long-term potentiation (LTP) in adult CA1 is contingent on activation of Ca/calmodulin-dependent protein kinase II (CaMKII). However, little is known about kinase mediation of LTP in the dentate gyrus. In the present study, the involvement of the kinases CaMKII, PKA, and MAPK i...
