How to use synapse

Synapse is a technical term used primarily in neuroscience, neurophysiology, and medical contexts to describe the anatomical and functional connection between neurons. It is the site where neurotransmitters are released and received, enabling communication in the nervous system. The word appears frequently in academic, medical, and scientific writing but rarely in everyday conversation.
