What are the largest and the smallest parts of the human brain?

Answer 1

The cerebrum is the largest and most developed part of the brain. It, unfolded, has the surface area of four school desks. It makes up 85% of the brain's weight. It's the center of judgment, reasoning, complex learning, abstract thinking, association, interpretation of sensory information, speech, learning and memory, and also controls voluntary actions, like how you think and move. It's made of two halves, the left and right cerebral hemispheres.

Answer 2

The largest parts of the Cerebrum, (Brain) are divided up into Cerebral Hemispheres and Lobes, however inside these are Neurons these are the smallest units of the Cerebrum and are therefore the smallest parts of the human brain. Scientists estimate that there are a vast number of Neurons in the human brain. Somewhere between 80 & 120 Billion neurons total. These nneurons are broken down into grups such as Motor Neurons for example. But that is not important at the time.
