Habituation is defined as a decrement in response as a result of repeated stimulation not due to peripheral processes like receptor adaptation or muscular fatigue. It is a process occurring within the nervous system (in animals with nervous systems).

Where does habituation occur in the brain?

The amygdala is one of the most-studied areas of the brain in relation to habituation.

How does habituation occur biology?

Habituation occurs when we learn not to respond to a stimulus that is presented repeatedly without change, punishment, or reward. ... During habituation, fewer neurotransmitters are released at the synapse. In sensitization, however, there are more pre-synaptic neurotransmitters, and the neuron itself is more excitable.
