Fight-flight-freeze isnt a conscious decision. Also, consider what triggered these feelings. They also preserve memories and attach those memories to specific emotions (such as happy, sad, joyous). Studies of the neural basis of emotion in animal models, including those focusing on the amygdala, typically have utilized physiological (e.g., autonomic) or behavioral (e.g., approach or defense) measures that likely reflect the valence and intensity of an emotional experience. the brain is like a tapestry of continuous fibers. After the response has passed, review what happened. This false alarm happens because the goal is to survive, there is an advantage to react first and think later. The amygdala is believed to be responsible for coordinating the. And, especially when it comes to neuropsychiatric disorders, the neuroanatomical models we use to hypothesize which brain targets to use are much less developed than the ones in neurology, he says.

It refers to situations wherein the amygdala hijacks control of a persons ability to respond rationally to a threat. Output from the amygdala can be directed to both subcortical and cortical brain structures. To understand why this happens, let's explore some basic neuroscience.
