A postsynaptic neuron is a receiving neuron that receives signals from other neurons across synapses. It contains receptors on its membrane that bind with specific neurotransmitters released by presynaptic neurons.
Dendrites are branched extensions of a neuron's cell body that receive incoming signals from other neurons.
Membrane Potential: Membrane potential refers to the difference in electric charge across the membrane of a neuron at rest or during signaling.
Excitatory Postsynaptic Potential (EPSP): EPSPs are temporary depolarizations of postsynaptic membranes caused by neurotransmitter binding, making the neuron more likely to generate an action potential.
