SAD – How Emotions Drive Stress, Anxiety and Depression

In the last blog, we looked at the chemical reaction in our brains, specifically with three of the 50+ communicating chemicals called “neuroamines” – either too much or too little can lead to either end of the spectrum of emotional issues i.e. panic attacks, depression, etc.

In this blog, we will go into more detail on how emotions drive us to stress, anxiety and depression. We have what are called “Three Brains” – the cerebral cortex, the limbic system and the brain stem. Here’s the process of how these three interact and produce the chemical reaction with emotions:


Cerebral Cortex – the front lines where information is taken in. When we experience or perceive something, we think about it.

Limbic – When our thoughts are produced, they are then sent to this system where the hippocampus assigns any memories we have of this experience/perception and the amygdala help assigns an emotion to that thought.

Brain Stem – When an emotion is assigned, the brain stem then regulates the body’s response to that emotion.
