Final answer:
The temporal lobe malfunction is likely causing Jarmaine's sensory deficits post-stroke, by affecting his hearing, vision, and olfactory-related taste perception.
Step-by-step explanation:
Based on the symptoms Jarmaine is experiencing after a stroke, including trouble with hearing, visual problems, numbness, and the recent change in his ability to taste food, it is likely that the temporal lobe of his brain is malfunctioning. The temporal lobe plays a key role in processing auditory information and is home to the auditory cortex as well as important areas related to memory, emotion, and some aspects of language comprehension. It is also involved in the processing of olfactory (smell) signals which are closely linked with the sense of taste. Damage to the temporal lobe can, therefore, lead to the variety of sensory deficits Jarmaine is experiencing.
