Question

The gyri and sulci on the brain greatly increase the brain’s surface area. How do you think this increase in surface area relates to improved brain function?

Answer 1

Answer:

Increase in surface area leads to more chances for connections between neurons hence more possible learning

Explanation:

The brain appears wrinkled due to the presence of gyri and sulci. Sulci are the grooves in the brain while gyri are the folds. The two major functions of gyri and sulci are to lead to formation of brain divisions and increase the surface area of cerebral cortex. The formation of brain divisions is done by creating boundaries between the brain lobes thereby leading to division of the brain into two hemispheres. Moreover, by increasing the surface area of the brain, the cortex processes more information since more neurons are formed.
