Figure 6. Model of a Neuronal Conduction of Excitation Without Action Potentials

Caption

Activation of neutral sphingomyelinase triggers ceramide production in rafts then the release of calcium from intracellular stores which activates the NO-cGMP pathway. This pathway activates downstream sphingomyelinase in neighbouring rafts which ensures the propagation of the excitation. L-Arg: L-arginine, NOS: NO synthase, GC: guanylate cyclase, nSmase: neutral sphingomyelinase.
