Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Cortical auditory area is localized in the:
A
temporal gyrus
B
central sulcus
C
occipital lobe
D
frontal gyrus
Explanation: 

Detailed explanation-1: -The primary auditory cortex (A1) is located on the superior temporal gyrus in the temporal lobe and receives point-to-point input from the ventral division of the medial geniculate complex; thus, it contains a precise tonotopic map.

Detailed explanation-2: -Superior temporal gyrus (STG) is the site of auditory association cortex (and a site of multisensory integration) and thus necessarily plays some role in spoken word recognition. Evidence that its role extends beyond that of higher-level perceptual processing was found as early as 1871 by Karl Wernicke.

Detailed explanation-3: -Anatomy and Physiology, Systems Auditory cortex in the superior temporal lobe consists of three major subdivisions, which are apparent cytoarchitectonically and histochemically: core, belt (which surrounds the core), and parabelt (PB), all of which contain several subfields.

Detailed explanation-4: -The auditory cortex is the part of the temporal lobe that processes auditory information in humans and many other vertebrates. It is a part of the auditory system, performing basic and higher functions in hearing, such as possible relations to language switching.

Detailed explanation-5: -The primary auditory cortex (Brodmann area 41, 42) is the part of the temporal lobe that is responsible for the conscious perception of sound. It is located in Heschl’s gyrus. It receives inputs from the medial geniculate nucleus.
