The connection between our brain and anxiety.
What is the science behind our brain function and anxiety?
In an attempt to better understand the scientific reasons behind anxiety it is important to look at how our brain functions. In the recent decade, research has shown when the link between the amygdala and the prefrontal cortex is weak, anxiety can result.
The amygdala, also known as the most primitive region in the brain is responsible for processing emotions, survival instincts and memory. It is responsible for our reactions to the events which can impact our survival. The amygdala increases responses such as heightened hearth rate and sweating, signally the potential life threatening situation which surrounds us.
The prefrontal cortex offers perspective to the situation. It allows us to evaluate the level of concern due to the conditions which surround us. It is the tool that assesses the situation rationally; although there is a potential poisonous spider, it’s behind glass on the outside of the window. The prefrontal cortex should recognise our immediate threat is lessened as a result of the glass being in place.
Research is now showing that this function, between the amygdala and the prefrontal cortex, can be hindered in people suffering from anxiety. The ability of these two areas of the brain to communicate effectively causes people to assume threats are more common and resulting in the body to be on alert more often.
The threats to our life, which surround us daily, have changed over time. In primitive times, treats from animals, predators and the environment required a greater level of awareness than what we see today. The research today suggests that in a state of anxiety, our perceived threat to life, although greatly reduced, is unable to be recognised as a realistic threat and we seem to be on alert more often than necessary. We often need to ask ourselves, what is the threat I am worried about? Is this threat a reality?
If we start to rationalise what causes us stress, and identify the eventuality of them occurring, we can start to gain an understanding towards how our brain is working against our optimal mental health, and change our outlook in life.
Professional services can support this process and should be consulted when ongoing concerns remain.
