Neurotransmitters: The Body's Chemical Messengers
- Axons are long, thin fibers that carry electrical signals away from the cell body.
- Neurotransmitters transmit messages from neurons to muscles.
- Reuptake is the process of reabsorbing neurotransmitters back into the presynaptic neuron.
- GABA is a natural chemical produced by the brain.
- Serotonin is produced from tryptophan, found in foods like salmon, turkey, and tofu.
Stress and Cortisol

- Epigenetics studies changes in gene expression without altering the DNA sequence.
- DNA methylation is a process involving adding a methyl group to DNA to regulate gene activity.
- Transgenerational epigenetics means inheriting chemical changes in gene expression through future generations.
Sleep, Dreams, and Biochemistry
- Melatonin is a hormone produced by the pineal gland that regulates the sleep-wake cycle.
- Acetylcholine promotes cortical arousal and desynchrony, essential for REM sleep.
- Mood disorders, sleep quality, and seasonal affective disorder (SAD) can be impacted by disrupted melatonin production.
The Biochemical Basis of Addiction
- Addiction is a chronic condition where individuals compulsively seek and use substances.
- Dopamine is a neurotransmitter strongly connected to the brain's reward system.
- Chronic alcohol use can disrupt the brain's glucose processing.
- Opioid (like heroin) use disrupts mitochondrial function, leading to lower brain cell energy.
- Serotonin is affected by drugs like ecstasy, influencing mood and cravings.
The Gut-Brain Connection
- The gut-brain axis represents the communication network connecting the gut and the brain.
- The gut produces neurotransmitters like serotonin and GABA.
Antioxidants and Brain Health
- Ascorbic acid is a water-soluble antioxidant that scavanges harmful reactive oxygen species (ROS) in the brain.
- Reactive oxygen species (ROS) are unstable molecules that react with other molecules, damaging cells.
- Antioxidants counteract these unstable molecules.
