|Brain: Temporal lobe|
|Frontal lobe is blue, parietal lobe yellow and temporal lobe green.
IsPartOf = Cerebrum
The temporal lobe is involved in auditory perception and is home to the primary auditory cortex. It is also important for the processing of semantics (meaning) in both speech and vision. The temporal lobe contains the hippocampus and plays a key role in the formation of long-term memory.
An area in the Sylvian fissure is the first place where auditory signals from the cochlea reach the cerebral cortex. This part of the cortex (primary auditory cortex) is involved in hearing. Other areas 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 (with Broca's area, which is in the frontal lobe). The functions of the left temporal lobe extends to comprehension, naming, verbal memory and other language functions.
The underside of the temporal lobes do high-level visual processing of faces and scenes. Front parts of this area are involved in object perception and recognition.
Deep inside the medial temporal lobes lie the hippocampus, which is essential for memory function – particularly the transfer from short to long term memory and control of spatial memory and behaviour.
