Question

What are the ridges and grooves called on the human brain?

Answer 1

Human brain:

The brain is a complex organ that controls our thoughts, memory, emotions, touch, motor skills, vision, respiration, temperature, and hunger.

Ridges and grooves:

1. The ridges are called Gyri, while the grooves are called Sulci.
2. Sulci surround each gyrus, which acts together to increase the surface area of the cerebral cortex and form brain divisions.
3. By increasing the surface area of the brain, more neurons may be packed into the cortex, increasing the cortex's processing power.
4. By precisely defining the boundaries between the lobes, they assist in dividing the brain into two hemispheres.
