Without the cerebellum, humans would be unable to do many things involving movement. This part is located at the edge of the skull. Within the cerebellum, there are hundreds of millions of neurons in which process data. The little brain is composed of white matter and a thin, outer layer of densely folded gray matter, (Bailey, (n.d.)).
The largest part of the brain is the cerebrum (Cerebrum function, (n.d.)). This part is the largest part of the vertebrate brain. The function of the cerebrum is to process thoughts and actions. The cerebral cortex has hemispheres that have an outer convoluted layer of grey matter. Underneath the cerebral cortex, a layer of white matter exists. In this part of the brain, it is estimated to be 10 billion nerve cells. The hemispheres are two halves of the cerebrum linked by corpus callosum (Dictionary of Biology, 2004).
Frontal lobe is extremely important for humans. The frontal lobe helps humans control decis...
