dendritic spines

Dendritic spines are small, tiny protrusions found on the branches of neurons (nerve cells) in the brain. They act as specialized sites where neurons connect and communicate with each other, playing a crucial role in learning and memory. Each spine can enhance or dampen signals received from neighboring neurons. The number and shape of these spines can change in response to experiences, a process known as synaptic plasticity. This adaptability is essential for processing information and forming new memories, highlighting their importance in the brain's functioning and overall cognitive health.
