If you are conscious and making sense of the world, you have your dorsolateral prefrontal cortex to thank. Same, if you can remember a string of numbers long enough to walk into the next room and punch them into a telephone keypad.
Live-Wise-Life's insight:
not sure the science is being reported in the correct way -acetylcholine is the bio-chemical nureotransmittor in the paritel lobe - Glutamine is the amno acid conected to the GABA nuerotransmitter which is in the temporal lobe . good news discovery. Again the bottom line is when the brain chemicals are balanced and working right the brain doesn't "crave" and you can eliminate unwanted behaviors.
