Perceived Threat → Fear → Amygdala → Fight-or-Flight
Fear activates the body's fight-or-flight response, preparing an individual to either confront or flee from the perceived threat.
Fear activates the amygdala, which signals the sympathetic nervous system to trigger the body's "fight-or-flight" response. This response prepares the body to either fight or flee from a threat
The primary neurotransmitter that activates during the "fight or flight" response is norepinephrine (noradrenaline), which is released alongside epinephrine (adrenaline)
The part of the brain most associated with anxiety symptoms is the amygdala, a part of the limbic system, which plays a crucial role in processing emotions and fear responses.
The mood disorder stress model, also known as the diathesis-stress model, posits that mood disorders arise from an interaction between an individual's predisposition (diathesis) and environmental stressors.
Jeffrey Gray’s behavioral inhibition system is a brain circuit in the limbic system that responds to threat signals by inhibiting activity and causing anxiety.
The more primitive brain stem monitors and senses changes in bodily functions and relays these potential danger signals to higher cortical processes through the limbic system.
