Alas, it is the end of the semester and you and your friend decide to go on that end of semester
hike that has become a tradition. You and your friend are walking in the woods and all of a sudden
they become afraid. After which they exclaim, in a fearful/humorous tone: "I was afraid of that
stick, haha, thought it was a snake for a split second!" You feel compelled to tell them that you
have learned about this in Behavioral Neuroscience. Your friend is intrigued and asks you to
explain. You state that when they saw the stick, they were afraid of it at first because the brain
possesses two routes of visual information processing when it comes to potentially fearful stimuli.
You go on by explaining that before they could tell what it was the _ had sent signals to the
which caused the fear response which represents a low road of visual processing.
