It is a survival mechanism, but we control it using our prefrontal cortex.

There is also a difference between reading silently, which is moderately stimulating, and reading out loud, which sets the prefrontal cortex going like the clappers.

Similarly, habitual impulsive criminals have an under-developed dorsolateral prefrontal cortex - the area thought to be involved in learning from mistakes.

It found a signal in a part of the brain called the right dorsolateral prefrontal cortex.

The brain regions affected by 'rosetinted spectacle syndrome' are the dorsolateral prefrontal cortex and the orbitofrontal cortex.
