Brodmann areas 41 and 42 are parts of the primaryauditory cortex.
Brodmann area 41 is also known as the anterior transverse temporal area 41 (H). It is acytoarchitectonic division of thecerebral cortex occupying theanteriortransverse temporal gyrus (H) in the bank of thelateral sulcus on the dorsal surface of the temporal lobe. Brodmann area 41 is bounded medially by theparainsular area 52 (H) and laterally by the posterior transverse temporal area 42 (H) (Brodmann-1909).
Brodmann area 42 is also known as the posterior transverse temporal area 42 (H), and is also a subdivision of the temporal lobe. Brodmann area 42 is bounded medially by the anterior transverse temporal area 41 (H) and laterally by thesuperior temporal area 22 (Brodmann-1909).
Brodmann areas 41 and 42 are parts of the primaryauditory cortex. This is the first cortical destination of auditory information stemming from the thalamus. Neural activity in this brain part corresponds most strongly with the objective physical properties of a sound.
