excitatory postsynaptic potential (EPSP)

An excitatory postsynaptic potential (EPSP) is a temporary change in the electrical charge of a neuron after it receives signals from other nerve cells. When a neuron is stimulated by neurotransmitters, it becomes more positive inside, making it easier for the neuron to fire and send signals of its own. This process plays a crucial role in communication between neurons, helping to transmit information and coordinate activities in the brain and nervous system. Essentially, EPSPs are key players in sending 'go' signals that enable various functions, from reflexes to complex thoughts.
