Ca V2.1 voltage activated calcium channels and synaptic transmission in familial hemiplegic migraine pathogenesis
Studies on the genetic forms of epilepsy, chronic pain, and migraine caused by mutations in ion channels have given crucial insights into the molecular mechanisms, pathogenesis, and therapeutic approaches to complex neurological disorders. In this review we focus on the role of mutated Ca V2.1 (i.e....
