- Synapse: A synapse is the specialized junction where one neuron communicates with another target cell, typically involving the release of neurotransmitters into the synaptic cleft.
- Receptor: A receptor is a protein on the surface or inside a target cell that binds to specific chemical messengers (like neurotransmitters) and initiates a resulting biological response.
- Excitatory Postsynaptic Potential (EPSP): An EPSP is a temporary depolarization of the postsynaptic membrane that makes the neuron more likely to fire an action potential.
- Inhibitory Postsynaptic Potential (IPSP): An IPSP is a temporary hyperpolarization of the postsynaptic membrane that makes the neuron less likely to fire an action potential.
