What describes spontaneous recovery?

• A. Neuroplasticity.
• B. Learned non-use.
• C. Spontaneous recovery.
• D. Collateral sprouting.

Answer: (C)

Spontaneous recovery is the natural return of function after a neurological injury that occurs without targeted rehabilitation. In the weeks to months following the event, improvements can happen as swelling diminishes, metabolic processes normalize, and dormant neural pathways become functional again, reflecting the body's inherent capacity to regain abilities. This phenomenon is distinct from neuroplasticity in general, which is the brain’s overall ability to reorganize itself; spontaneous recovery describes the observable regain of function that can occur as part of that reorganization. Learned non-use describes a behavior where a person stops using a weaker limb, which can hinder recovery rather than describe spontaneous improvement. Collateral sprouting refers to new sprouting from nearby neurons to reinnervate the affected area and can be a mechanism contributing to recovery, not the spontaneous improvement itself.
