Question

46. In this same “masking” experiment, MRI analysis showed a marked activation of the amygdala to emotional stimuli, such as angry faces that had previously been paired with a loud white noise. This activation occurred even though the subject did not recall seeing the face. What can you conclude from these results? Question options: A) The fusiform gyrus is not involved in facial threat analysis B) The brain uses the same neural circuits for threatening stimuli as it uses for “blindsight” C) The brain uses multiple circuits to analyze visual stimuli

an explanation would be helpful thank you

Explanation / Answer

Ans. The activation which occured even though the subject did not recall seeing the face was due to, the brain using the same neural circuits for threatening stimuli as it uses for "blindsight." The appropriate option is option B. It is associated with the patients ability ot differentiate between the emotional content of stimuli which cannot be seen consciously. The proficiency is associated with the activity in amygdala. The neural circuits which are used for eliciting response are not segregated but would elicit a response for conscious and non conscious response processing. The initial response determines whether the stimulus would reach for the awareness. The temporal dimension of amygdala response becomes critical to its role in emotion response with or without awareness.
