Question

question 6
which of the following is true of tinnitus in adults?
promotes better quality hearing in one ear
leads to degeneration restricted to the contralateral auditory cortex
it is when the olfactory bulb does not send signals to the amygdala
it is when optic nerve transfers visual information to the brain via electrical signals
it is a ringing in the ear that leads to a reorganization of primary auditory cortex

Explanation:

Tinnitus is characterized by a ringing in the ears. Research has shown that chronic tinnitus can lead to reorganization of the primary auditory cortex as the brain tries to adapt to the abnormal auditory input.

• The first option is incorrect as tinnitus impairs hearing quality rather than promoting better hearing.
• The second option is wrong because tinnitus - related changes are not restricted to the contralateral auditory cortex only.
• The third option is about the olfactory system (related to smell) and has nothing to do with tinnitus (auditory system).
• The fourth option is about the optic nerve (visual system), not relevant to tinnitus.

Answer:

it is a ringing in the ear that leads to a reorganization of primary auditory cortex
