Page 1: Brain Plasticity and Recovery Mechanisms
The first page explores the fundamental concepts of brain plasticity and functional recovery, supported by key research studies. The brain's ability to adapt through plasticity involves creating new neural pathways while removing unused connections through synaptic processes.
Definition: Plasticity refers to the brain's ability to adapt its structures and functions based on experiences and learning.
Example: Maguire's study of London taxi drivers revealed increased grey matter in their hippocampus, demonstrating experience-based brain changes.
Vocabulary: Synaptic bridging refers to the creation of new neural pathways, while synaptic pruning involves removing unused connections.
Highlight: Functional recovery involves three key mechanisms: axonal sprouting, blood vessel reformation, and neural reorganization.
The text details how functional recovery allows the brain to redistribute functions from damaged to undamaged areas through spontaneous recovery and gradual healing. Research by Aijiri et al. demonstrated how stem cells could develop into neuron-like cells in injured areas, while Kuhn's study showed increased grey matter in video game players.
Quote: "The brain continues to create new neural pathways and alter existing ones in response to changing experiences."
