The temporal lobes are part of the cerebrum. They lie at the sides of the brain, beneath the lateral or Sylvian fissure. Seen in profile, the human brain looks something like a boxing glove.

Function

The superior temporal gyrus includes an area (within the Sylvian fissure) where auditory signals from the cochlea (relayed via several subcortical nuclei) first reach the cerebral cortex. This part of the cortex (primary auditory cortex) is involved in hearing. Adjacent areas in the superior, posterior and lateral parts of the temporal lobes are involved in high-level auditory processing. In humans this includes speech, for which the left temporal lobe in particular seems to be specialized. Wernicke's area, which spans the region between temporal and parietal lobes, plays a key role (in tandem with Broca's area, which is in the frontal lobe). The functions of the left temporal lobe are not limited to low-level perception but extend to comprehension, naming, verbal memory and other language functions. Sound processing is controlled by the temporal lobes- in the Broca’s area and Wernicke’s area. Superior temporal gyrus of the human brain. ...

The primary auditory cortex is the region of the brain that is responsible for processing of auditory (sound) information. ... Wernickes area is a part of the human brain that forms part of the cortex, on the left posterior section of the superior temporal gyrus, encircling the auditory cortex, on the Sylvian fissure (part of the brain where the temporal lobe and parietal lobe meet). ... Brocas area is the section of the human brain (in the opercular and triangular sections of the inferior frontal gyrus of the frontal lobe of the cortex) that is involved in language processing, speech production and comprehension. ...


The underside (ventral) part of the temporal cortices appear to be involved in high-level visual processing of complex stimuli such as faces (fusiform gyrus) and scenes (parahippocampal gyrus). Anterior parts of this ventral stream for visual processing are involved in object perception and recognition. Face perception is the process by which the brain and mind understand and interpret the face, particularly the human face. ... The fusiform gyrus is part of the temporal lobe. ... The parahippocampal gyrus (or hippocampal gyrus) is a grey matter cortical region of the brain that surrounds the hippocampus. ... The primate visual system consists of about thirty areas of the cerebral cortex called the visual cortex. ... Visual processing is the sequence of steps that information takes as it flows from visual sensors to cognitive processing. ...


The medial temporal lobes (near the Sagittal plane that divides left and right cerebral hemispheres) are thought to be involved in episodic/declarative memory. Deep inside the medial temporal lobes, the hippocampi seem to be particularly important for memory function - particularly transference from short to long term memory and control of spatial memory and behavior.

Temporal lobe - definition of Temporal lobe in Encyclopedia (351 words)
The temporal lobe encloses the hippocampus and amygdala.
The medial temporal lobe (near the sagittal plane that divides left and right cerebral hemispheres) is thought to be involved in episodic/declarative memory.
Deep inside the medial temporal lobe, the hippocampus seems to be particularly important for memory function, and it also seems to play a part in controlling spatial behavior.
MedlinePlus Medical Encyclopedia: Temporal lobe seizure (1170 words)
Temporal lobe seizures can affect people of any age, and can occur as a single episode or can be repeated as part of a chronic (ongoing) condition.
Because the temporal lobe is involved in processing emotion and sensations, seizures in this area may begin with feelings of fear, feelings of joy (sometimes with religious associations and the sensation of a "presence"), recall of certain music, or smells and other unusual symptoms.
Diagnosis of temporal lobe seizure is suspected primarily on the basis of the symptoms presented and the results of testing.
