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 the superior temporal area 22 (Brodmann-1909).
Function
Brodmann areas 41 and 42 are parts of the primary auditory 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.
