a. the mag of ap is greater in hippocampal than cortical neurons
b. the expression of nmda receptors is more abundant in hippocampal than cortical neuorns
c. hippocampal neurons generate a more negative postsynaptic potential than cortical neurons
d. hippocampal synapses have faster neurotransmitter diffusion rates compared to cortical synapses
