Study Notes
Neuroplasticity and Synaptic Function
- Neuroplasticity refers to the brain's ability to change structurally and functionally following trauma.
- In the 1960s, researchers discovered that brain cells can reorganize themselves after a stroke, leading to new connections and pathways.
- Wall (1977) identified 'dormant synapses' in the brain, which are inactive but can be activated to compensate for damaged areas.
