The Science of Fear

The video explores the concept of fear, its physiological effects, and the neural pathways involved. It distinguishes between emotions and feelings, highlighting the role of the amygdala in processing fear and emotional memories. The amygdala's various regions are linked to different fear responses. The video also emphasizes the brain's capacity to form new connections with each new memory.

What is the primary purpose of the neural circuit related to fear?

• To enhance memory retention

• To keep an organism alive in dangerous situations

• To improve cognitive functions

• To regulate sleep patterns

How are emotions different from feelings according to the video?

• Feelings are products of the conscious mind, while emotions are patterns of neuronal behavior

• Feelings are physiological reactions, while emotions are not

• Emotions are conscious experiences, while feelings are unconscious

• Emotions are voluntary, while feelings are involuntary

Where are the memories of fear stored in the brain?

• In the hippocampus

• In the amygdala

• In the prefrontal cortex

• In the cerebellum

Which part of the amygdala is associated with fear responses?

• The caudal aspects

• The rostral regions

• The central nucleus

• The lateral nucleus

What happens in the brain when a new memory is formed?

• Old memories are erased

• The amygdala shrinks

• The hippocampus becomes inactive

• New brain connections are created
