If the human cortex did not have so many folds,what would be likely

A)  We would not need the cerebellum. 
B)  We would have faster transmission of action potentials. 
C)  We would lose the ability to inhibit most neural impulses. 
D)  We would need larger skulls to hold the same brain volume.

Human Cortex

The outer layer of the brain involved in high-level functions such as consciousness, thought, emotion, reasoning, language, and memory.

Brain Volume

The total volume of the brain, including the cerebral cortex and subcortical structures, which can be measured through imaging techniques and has implications for various cognitive and physical health conditions.

Larger Skulls

Referring to an evolutionary trait wherein species, including humans, have developed skulls of a greater volume, often associated with changes in brain size and cognitive abilities.
