HOW THE BRAIN WORKS

Whould you like to know the Cerebrum Is the Control Center of the Brain

 Although vertebrate brains differ in the relative importance of different components. the human brain is a good model of how Vertebrate brains function. About 85% of the weight of the human brain is made up of the cerebrum, the tan convoluted area in . The cerebrum is a large rounded area of the brain divided by a groove into right and left halves called cerebral hemispheres. The sectioned brain in
is cut along the center groove, with the left hemisphere removed, showing the right hemisphere. The cerebrum functions in language, conscious thought, memory, personality development. vision, and a host of other activities we call "thinking and feeling."  shows general areas of the brain color-coded for easy identification (yellow for the frontal lobe, orange for the parietal lobe, light green for the occidental
lobe, and light purple for temporal lobe) and the functions they control. The cerebrum, which looks like a wrinkled mushroom. is positioned over and surrounding the rest of the brain. like a hand holding a fist. Much of the neural activity of the cerebrum occurs within a thin. gray outer layer only a few millimeters thick called the cerebral cortex (cortex is Latin for "bark of a tree"). This layer is gay because it is densely packed with neuron cell bodies. The human cerebral cortex contains the cell bodies of more than II) billion nerve cells, roughly 10% of all the neurons in the brain. The wrinkles in the surface of the cerebral cortex increase its surface area (and number of cell bodies) threefold. Underneath the cortex is a solid white region of eliminated nerve fibers that shuttle information between the cortex and the rest of the brain.
