'''Brodmann areas 41 and 42''' are parts of the primary [[auditory cortex]]. 

[[Brodmann area]] 41 is also known as the anterior transverse temporal area 41 (H). It is a [[cytoarchitecture|cytoarchitectonic]] division of the [[cerebral cortex]] occupying the [[Anterior#Anterior and posterior|anterior]] [[transverse temporal gyrus]] (H) in the bank of the [[lateral sulcus]] on the dorsal surface of the temporal lobe. Brodmann area 41 is bounded medially by the [[Brodmann area 52|parainsular 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 the [[Brodmann area 22|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.
