Study Notes
Synaptic Pruning
- Synaptic pruning is a natural process that occurs in the brain between early childhood and adulthood.
- During pruning, the brain eliminates extra synapses, which are brain structures that allow neurons to transmit signals to each other.
- This process is like "cleaning" the mind, and it's influenced by genes in early years and life experiences in later life.
- Pruning is essential for the brain's efficiency, allowing it to remain efficient and adapt to new complex information as we age.
- Emotionally connected information is more difficult to forget or prune.
Brain Development
- At 2-3 years old, the brain has the most synapses it will ever have, and then pruning begins.
- Between 2-10 years old, about 50% of synapses are lost.
Importance of Sleep
- Good sleep is necessary for effective pruning.
- Waking up during the REM cycle can negatively impact pruning.
Neuroplasticity
- Neuroplasticity is the brain's ability to change and adapt in response to experiences and learning.
- It enables the brain to make changes to itself, including forming new neuronal connections.
Types of Neuroplasticity
- Functional neuroplasticity: the brain's ability to move functions from damaged areas to undamaged areas.
- Structural neuroplasticity: the brain's ability to change its physical structure as a result of learning.
Promoting Neuroplasticity
- Ways to promote neuroplasticity include learning a new language, expanding vocabulary, using the non-dominant hand, creating artwork, reading, learning new skills, doing puzzles, and mindfulness meditation.
