What is the Origin of Cortical Plasticity?

Derived from the Latin cortex (bark, outer layer) and the Greek plastos (molded), this term describes the changeable nature of the brain's outer structure. Its scientific origin is rooted in foundational neuroscience demonstrating functional redundancy and reorganization capabilities.

What is the Mechanism of Cortical Plasticity?

Plasticity is actively regulated by the balance of excitatory and inhibitory neurotransmission, significantly influenced by neurotrophic factors like BDNF, which themselves respond to systemic health. Adequate hormonal signaling, particularly from thyroid and sex steroids, promotes synaptogenesis and the stabilization of new dendritic spines, enhancing the physical substrate for adaptation.

Cortical Plasticity

Meaning

Cortical Plasticity refers to the inherent neurobiological malleability of the cerebral cortex, allowing for structural and functional reorganization throughout life in response to experience, learning, or injury. This capacity for dynamic rewiring is fundamental to cognitive adaptation and recovery. It is the brain’s ability to remodel its own circuitry.
