Neurobiological bases of rehabilitation.
Level 5 - mechanism / opinion, no new human data
Narrative review of neurobiological mechanisms without original human data or systematic synthesis

What was done
Narrative review summarizing the neurobiological mechanisms underlying adult motor cortex reorganization and their conceptual application to patient rehabilitation following brain injury.
What was found
The abstract reports no numerical findings or statistical data. It describes that motor cortical representations reorganize rapidly through the unmasking of latent horizontal connections, synaptic efficacy changes, and modulation of GABAergic inhibition. Following motor cortex injury, alterations include neurotransmitter system changes, recruitment of remote undamaged areas, and anatomical alterations including axonal sprouting and synaptogenesis in perilesional and homotopic contralateral cortex.
Why it matters
This review outlines the cellular and circuit-level plasticity mechanisms that serve as the theoretical foundation for post-stroke and post-injury motor rehabilitation.
Limits
As a narrative review, it presents no primary clinical data, quantitative effect sizes, or systematic study selection criteria in the abstract.
