The cerebrum of our BRAIN is the largest part,, it’s weight is 85 percent of the total weight of our BRAIN.. The cerebrum has two halves,, or hemispheres.. It is further divided into four regions,, or lobes,, in each hemisphere.. The frontal lobes,, located behind the forehead,, are involved with speech,, thought,, learning,, emotion,, and movement.. Behind them are the parietal lobes,, which process sensory information such as touch,, temperature,, and pain.. At the rear of the BRAIN are the occipital lobes,, dealing with vision.. Lastly,, there are the temporal lobes,, near the temples,, which are involved with hearing and memory..

The cerebral cortex lies in distinctive deeply wrinkled outer surface consists of gray matter.. The white matter lies beneath this area.. It's the cerebrum that makes the human BRAIN.. Whereas animals such as elephants,, dolphins,, and whales have larger BRAIN,, humans have the most developed cerebrum.. It's packed to capacity inside our skulls,, enveloping the rest of the BRAIN,, with the deep folds cleverly maximizing the cortex area..
