The Temporal Lobe and Parietal Lobe
The TEMPORAL LOBE and PARIETAL LOBE
TEMPORAL LOBE
Introduction The temporal cortex, also known as the temporal lobes, is the part of the verbal cortex in the left and right hemispheres of the brain lying inside the temples. In general the temporal lobes handle a wide variety of task that are essential to every day functioning.
Readily recognizable brain structures with thumb like appearance when viewed from the side. Their name reflects their location beneath the temporal bone on the side of the head. They share borders with occipital and parietal lobes, but the precise boundaries are not clearly defined by landmarks. A better definition of the anatomical limits of the temporal lobe would come from thalamic and intra-cortical projections and a functional analysis of the various subunits within the lobe. Because excision of the anterior temporal lobe is often used to help control medically intractable seizure disorders, much of our knowledge of the effects of damage to this area comes from studies of persons with epilepsy (Encyclopedia of the Human Brain).
Functions * Auditory Senses * Adjacent areas in the superior, posterior, and lateral parts of the temporal lobes are involved in high-level auditory processing. * The temporal lobe is involved in primary auditory perception, such as hearing, and holds the primary auditory cortex. * The primary auditory cortex receives sensory information from the ears and secondary areas process the information into meaningful units such as speech and words. * The superior temporal gyrus includes an area (within the lateral fissure) where auditory signals from the cochlea first reach the cerebral cortex and are processed by the primary auditory cortex in the left temporal lobe. * Visual Senses * The areas associated with vision in the temporal lobe interpret the meaning of visual stimuli and establish object
