Question

damage to the auditory cortex on one side of the brain will lead to deafness in that ear.

select one:
true
false

which of the following arrows is pointing to the location where taste is processed?

Explanation:

Analyze unilateral auditory cortex damage

The first question asks whether damage to the auditory cortex on one side of the brain leads to deafness in that ear.

In Auditory Physiology, auditory pathways from each ear project bilaterally to both cerebral hemispheres. Because of this extensive decussation (crossing over) of fibers in the brainstem, each auditory cortex receives sensory input from both ears. Therefore, unilateral damage to the primary auditory cortex does not cause complete deafness in either ear; instead, it primarily leads to difficulties in sound localization and interpreting complex sounds. Thus, the statement is False.

Identify the cortical area for taste processing

The second question asks which arrow points to the location where taste is processed (the gustatory cortex).

The primary gustatory cortex is located in the insula and the adjacent operculum of the frontal and parietal lobes, deep within the lateral sulcus.

• Image a shows an arrow pointing to the lateral sulcus / superior temporal gyrus region (associated with the auditory cortex).
• Image b shows an arrow pointing deep into the lateral sulcus/insula region (the gustatory cortex, highlighted in orange/pink deep within the fold). Therefore, arrow b correctly points to the gustatory cortex where taste is processed.

Answer:

Question 1

• True
• False (Correct answer)

Question 2

• a.
• b. (Correct answer)
