Involvement of calcium–calmodulin protein kinase but not mitogen‐activated protein kinase in light‐induced phase delays and Per gene expression in the suprachiasmatic nucleus of the hamster

Abstract
It is known that Ca2+‐dependent phosphorylation of cAMP response element binding protein (CREB) and the rapid induction of mPer1 and mPer2, mouse period genes in the suprachiasmatic nucleus (SCN) are...
