Fear

Brain Facts

Posted by Safe In4 Hub

Parts of Our Body's Fear System


Amygdala: scans for threats and signals body to respond

Brain Stem: triggers the freeze response

Hippocampus: turns on the fight-or-flight response

Hypothalamus: signals the adrenal glands to pump hormones

Pre-Frontal Cortex: interprets the event and compares it to past experiences

Thalamus: receives input from the senses and "decides" to send information to either the sensory cortex (conscious fear) or the amygdala (defense mechanism)
