Brain on fear
Neurofunction change in fear.
Not only do we change the chemistry of our body, but the stress hormones change the operation of the brain.
When we are in fear, the stress hormones squeeze shut the blood vessels in the forebrain, which is conscious reasoning and logical thinking, and forces the blood to behind the brain where we operate from reactive behavior… which is not thinking at all, it’s just stimulus response.
So the nature is: as we become more engaged in fear, we become less intelligent.
