👉 The term "antennal" is a term that refers to the structure of a person's brain, particularly in the part of the brain known as the cerebellum. The cerebellum is responsible for coordinating and regulating movement and balance, and it is one of the most important parts of the human brain. In terms of antennal function, it is possible that there may be some connection between the cerebellum and the antennae in the brainstem or other parts of the body.
