AP PSYCHOLOGY

Detailed explanation-1: -Auditory stimulation is first processed in the brain’s primary auditory cortex (A1), located in the superior temporal gyrus of the temporal lobe (Brodmann areas 41 and 42). Its primary function is to process sound (volume and pitch) and detect the location of the sound.

Detailed explanation-2: -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-3: -The processing of decoded sound material starts within the primary auditory pathway. This pathway carries messages from the cochlea to a sensory area of the temporal lobe called the auditory cortex.

Detailed explanation-4: -The auditory pathway starts at the cochlear nucleus, then the superior olivary complex, then the inferior colliculus, and finally the medial geniculate nucleus. The information is decoded and integrated by each relay nucleus in the pathway and finally projected to the auditory cortex.
