Question

1. What main pathway(s) are Not primarily known to be activated by threat?

a. Descending auditory cortico-thalamic pathway

b. Dorsomedial thalamus to secondary cerebral cortex

c. Ventral thalamus to primary cerebral cortex

d. Dorsal cochlear nucleus to auditory cerebral cortex

Expert Solution
Step 1

The term threat can be described as a state of mind that gives a feeling of fear, fear of encountering something wrong, which can cause injury or damage to the body. This sensation of fear triggers the activation of many pathways in the body.

Step 2

The descending auditory cortico-thalamic pathway and the dorsal cochlear nucleus pathway to the auditory cerebral cortex are primarily involved in the transmission and interpretation of auditory signals.

Hence, the correct options are ‘a and d.’
