Which of the following best explains the pathophysiology of this presentation?
Four weeks after a stroke that left a 66-year-old female patient paralyzed in the right lower half of the face only; she presented to her doctor with the inability to clearly identify taste sensation on the left side of her tongue while still retaining the ability to respond emotionally to especially noxious substances. The doctor checked this complaint by giving her quinine to taste. Although she couldn’t specifically describe the taste of quinine, she reacted to the taste in a way that suggested disgust.



A. The stroke affected the primary somatosensory cortex and caused loss of conscious taste sensation
B. The stroke affected the cingulate gyrus and compromised the patient’s emotional response to taste
C. The stroke affected the premotor cortex and compromised the patient’s psychomotor response to taste
D. The stroke affected the tractus solitarius in the brainstem and compromised conscious taste perception
E. The stroke damaged the insula while sparing the limbic cortex
