Coronal section of a human brain. BA41(red) and BA42(green) are<unk> . BA22(yellow) is Brodmann area 22, HF(blue) is hippocampal formation and pSTG is posterior part of superior temporal gyrus. The<unk>  is the part of the temporal lobe that processes<unk>  information in humans and many other vertebrates. It is a part of the<unk>  system, performing basic and higher functions in hearing, such as possible relations to language switching. It is located bilaterally, roughly at the upper sides of the temporal lobes – in humans, curving down and onto the medial surface, on the superior temporal plane, within the lateral sulcus and comprising parts of the transverse temporal gyri, and the superior temporal gyrus, including the planum polare and planum temporale (roughly Brodmann areas 41 and 42, and partially 22). The<unk>  takes part in the spectrotemporal, meaning involving time and frequency, analysis of the inputs passed on from the ear. The cortex then filters and passes on the information to the dual stream of speech processing. The<unk> 's function may help explain why particular brain damage leads to particular outcomes. For example, unilateral destruction, in a region of the<unk>  pathway above the cochlear nucleus, results in slight hearing loss, whereas bilateral destruction results in cortical deafness.
