Come to the calm of a well functioning brain.
Fear and the Brain....
We are hard wired to experience fear. It is a reaction that evolved to protect organisms against perceived threat. The chemicals in the brain that are involved in fight or flight are also involved in the positive states: such as happiness and excitement.
Fear is related to content. Some people get scared with the mention of a mouse and jump on the nearest chair. This would not affect other people but some other trigger could get them going. (How about a snake or rhinoceros in your yard) What happens is the amygdala sends out the reaction to the body and gets it into motion. When there is a fear reaction, the higher brain functions can also get involved. There is a place called the hippocampus that starts to access the problem and gets the prefrontal cortex involved. Oh, that was not a spider but just a piece of thread. If it is a real threat then the stress hormones and the sympathetic nervous system kick in and the brain goes into hyper-arousal. The body follows by increased heart rate, pupils dilate, the stomach shuts down and off we go.
When there is a problem with the response and the brain and body don't shut down then this can lead to a serious mental health problem such as obsessive compulsive disorder.
LENS neurofeedback can help to quiet the over anxious brain.
