Genes
What is the estimated percentage of synapses lost between the ages of 2 and 10?
40-50%
What is a negative effect of waking up during the REM cycle on synaptic pruning?
It disrupts the pruning process
What is the role of neuroplasticity in the development of the adult brain?
It enables further growth and development
What is the main difference between functional and structural neuroplasticity?
Functional neuroplasticity is related to brain function, while structural neuroplasticity is related to brain structure
What can be a negative consequence of synaptic pruning gone wrong?
Development of psychiatric disorders
What is the brain's ability to move functions from a damaged area to other undamaged areas?
Functional neuroplasticity

It is necessary for the pruning process to occur
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.
Learn about synaptic pruning, a natural process in brain development where extra synapses are eliminated, and its relationship with sleep and emotional connections.
