The cerebellum is part of the lower hindbrain, and is important when performing tasks that require timing for example a baseball player hitting a baseball. It also helps in judging whether or not one sound is louder than the other. The cerebellum is the part of the brain that controls moves of attention from one stimulus to another. The cerebral cortex is the outer covering of the forebrain. The cerebral cortex is often referred to as "gray matter," and is made up of four lobes. The first lobe is the occipital lobe, which is located at the back of the head. This lobe is used for vision for example recognizing different shapes, colors, and certain motions. The next lobe is the parietal lobe and is located just in front of the occipital lobe. The parietal lobe is used in reporting different senses such as pain, temperature, touch, and where the body parts are located. The temporal lobe, which is located to the left and right sides of the brain, is the main section for processing sound and details in vision. One area in the left side of the temporal lobe is responsible for understanding language. If this area is damaged some doctors say it can cause the person to be unable to understand what another person is saying, and may not be able to recognizing or naming objects. The structure of neuron connections of the left and right parts of the temporal lobe are different leaving the right side responsible for details in vision such as detection of motion and recognition of different facial expressions. Another part of the temporal lobe is the amygdala, which is responsible for some types of emotion. If a person has damage done to the amygdala they are left with no feelings of fear or anxiety. They also cannot remember emotionally stressed events because they have no feelings of being emotionally stressed. There is no way that they can imagine what a scared expression would look like or what it is like to be scared.
