Narrative review of animal and human studies without systematic review methodology

What was done
The authors reviewed animal research as well as behavioral and functional neuroimaging studies in sighted and blind human individuals to examine structural, functional, and behavioral adaptations following visual deprivation.
What was found
The abstract reports no numerical data. It notes qualitatively that visual deprivation causes structural changes across brain regions, drives cross-modal recruitment of the visual cortex for non-visual sensory and cognitive processes, and is accompanied by enhanced behavioral acuity for auditory and tactile modalities.
Why it matters
This review synthesizes evidence on cross-modal neuroplasticity, clarifying how sensory experience shapes functional brain architecture and perception in the absence of vision.
Limits
As a narrative review, it lacks systematic search criteria, quality appraisal, and pooled effect sizes. Specific sample sizes and patient characteristics are not reported in the abstract.
