Study Notes
Neuroplasticity: Key Concepts and Applications
- Rats in enriched environments showed thicker cortices compared to those in basic environments
- Historical milestones in neuroplasticity, including Hubel and Wiesel's study on brain activity and Merzenich's findings on cortical reorganization
- Eleanor Maguire's documentation of changes in the hippocampus of London taxi drivers
- Definition of neuroplasticity as the nervous system's ability to reorganize its structure and function in response to stimuli
- Neuroplasticity can occur at molecular, cellular, system, and behavioral levels and during various stages like development or after therapy
- Mechanisms of neuroplasticity, including changes in neurons, between neurons, and in networks of neurons
- Neuroplasticity is activity-dependent, with the principle "neurons that fire together, wire together"
- Neuroplasticity in development involves brain growth, critical periods, and ongoing neurogenesis in specific brain areas
- Applications of neuroplasticity, such as in cerebellar agenesis, stroke rehabilitation, and hemispherectomy
- Adverse examples of neuroplasticity, including chronic pain after limb amputation and theories about phantom limb sensations
- The role of neurotrophins like BDNF in neuroplasticity, particularly in motor learning and memory after stroke
- The potential for neuroplasticity in various clinical scenarios, such as blindness and severe epilepsy, and its unknown degree in adults
