Question

Quizplus · Accepted Answer

The summing up of excitatory and inhibitory signals in a neuron is called synaptic integration. This process occurs at the synapse, where neurotransmitters bind to receptors on the postsynaptic neuron's dendrites and cell body, resulting in either depolarization (excitatory) or hyperpolarization (inhibitory). Ultimately, the signals are integrated at the axon hillock, where the decision is made whether to fire an action potential or not.
