Q
  • What happens after the receptor is activated??

Channels- Receptors - proteins

A
  • Postsynaptic dendrite:
  • Transmitter-gated ion channels (ionotropic receptors) G-protein-coupled receptors (metabotropic receptors) G-proteins
    G-protein-gated ion channels
    Second messenger cascades
