Describe the structural domains of neurons that allow signal integration and conduction of action potentials

Excitatory synapse – binding of a neurotransmitter to the receptor-channel results in the opening of nonselective cation channels in the postsynaptic membrane that permit simultaneous passage of Na+ and K +ions Excitatory Postsynpatic Potential (EPSP) – small depolarization of the postsynaptic neuron. Inhibitory synapse – binding of a neurotransmitter with its receptor-channels opens either K+ or Cl- channels in the postsynaptic membrane Inhibitory Postsynpatic Potential (IPSP) – small hyperpolarization of the postsynaptic neuron
