Stimulants enhance the effects of these chemicals in the brain. Stimulants also increase blood pressure and heart rate, constrict blood vessels, increase blood glucose, and open up the pathways of the respiratory system. The increase in dopamine is associated with a sense of euphoria that can accompany the use of these drugs. HOME...... Brain Food LINKS: ....Medical Dictionary ....Stress Management ....Allergy Info |
