Question

sensory information that creates a fear response is first routed through the what?

Answer 1

Fear is a part of human emotion which is felt by the human where there is a situation of threat, danger or a unpleasant harm to the individual.

The first sensory stimulus about fear is received by the amygdala and then it firstly toured to the thalamus part of brain. From the thalamus it is divided into two parallel routes named as thalamo-amygdala pathway which is a short route and thalamo-Cortico amygdala pathway which is long route that carries information about the fear emotion.

So, Thalamus is the brain part that first routes the fear response created by the sensory information received to the brain.
