In fact, habituation in planaria survives regeneration; when a planarian is split in two, both new planaria exhibit the response learned by the original one. Increased response magnitude, or sensitization, can also occur to a repeated stimulus if it is of high intensity or aversive (unpleasant).

There are two well-known types of non-associative learning: habituation and sensitization. Habituation is a decrease in response to a benign stimulus when the stimulus is presented repeatedly. A dog will be aroused when a strange tone is played.

Habituation is a reduction in a previously-displayed response when no reward or punishment follows. ... Sensitization is an increase in the response to an innocuous stimulus when that stimulus occurs after a punishing stimulus.

(1) Facilitation was induced by stimulation of the novel site before habituation training at the trained site, although the stimulus intensity at the novel site was equivalent to the training stimuli and was not the strong, noxious stimuli that normally induce sensitization.

The results suggest that startle sensitization is enhanced by increased availability of catecholamines and, by virtue of the different potencies of the d- and l-isomers, that dopamine and norepinephrine may affect startle differently. ... Habituation, Psychophysiologic [drug effects]

Habituation and sensitization are two fundamental learning processes. In each case, animals change their reactions to a stimulus with repeated stimulation. Habituation is defined as a decrease in responsiveness to a stimulus, as is seen in ingestional neophobia (decreased avoidance of a novel food over time).

Habituation and sensitization are controlled by different mechanisms, as described in the dual-process theory. Habituation is a function of the S-R system, or changes in the neurons controlling the response,
