The reticular activating system is also involved in directing incoming information to appropriate brain stem nuclei that control autonomic functions transmitting information to the forebrain for conscious sensations. The limbic system is often referred to as the emotional brain because one of its functions is emotions. The cerebral hemispheres physically dominate the structure of the brain. Many functional areas of the brain gyri have been identified. Four pairs of lobes are present in the cerebrum and various functions have been associated with these lobes.
Temporal lobes receive and process auditory information.
Association areas of the temporal lobes are involved in recognition, identification, and naming of objects. Occipital lobes receive and process visual information. Parietal lobes are separated from the frontal lobes by the central sulcus . The part of each parietal lobe immediately behind the central sulcus is the primary somatosensory cortex . This area receives information through the thalamus about touch and pressure sensations.
