| Type | Function |
| (1) Strengthening of cognitive functions | Skill learning (e.g., [145]) |
| (2) Hemispherectomy | Removal of one hemisphere to treat a variety of seizure disorders, leading to a takeover of functions that were initially performed by or in combination with the removed hemisphere (e.g., [146]) |
| (3) Sensory substitution | Compensation of sensory loss by another sense or external device (e.g., [147]); for a review addressing differences within hearing restoration by cochlear implantation, see [97] |
| (4) Early deprivation | Early loss due to a genetic or medical condition leading to compensation and broad takeover by other senses, although functional topography appears inert as dual streams (dorsal and ventral) remain intact; reorganization mainly occurs through bottom-up processing (e.g., [148, 2]) |
| (5) Late deprivation | Rather supportive in nature; compensation for the loss is restricted due to initial pruning and functional reorganization; rather through top-down processes (e.g., [148, 2]) |
| (6) Site of plastic changes | Cross-modal, intracortical, or even within the sensory organ (e.g., the retina [144]) |
|
| Influencing factors | |
| (1) Sensitive/critical periods | |
| (2) Other senses and their critical periods [149] | |
| (3) Age of onset of deprivation | |
| (4) Duration of deprivation | |
| (5) Degree of loss [142] | |
| (6) Cause of sensory deprivation | |
| (7) Working memory, intelligence quotient, gender (…) (e.g., see also the Ease of Language Understanding (ELU) model [150]) | |
