Inhibitory Postsynaptic Potential

A type of synaptic potential that makes a post-synaptic neuron less likely to generate an action potential, usually by making the inside of the neuron more negative.

Neuronal Membrane

The lipid bilayer that encases neurons, regulating the entry and exit of substances and maintaining the electric potential used for neural transmission.
