Acetylcholine is most commonly known as the neurotransmitter active in constriction, but it also has secondary effects on mood. Higher concentrations of acetylcholine have been associated with anxious or depressive behaviors. Nicotine’s chemical structure is similar that of acetylcholine’s and has the ability to block the receptors that accept the acetylcholine molecules. This implies that—at least temporarily—nicotine reverses the mood effects of acetylcholine. While the exact mechanism of these disorders is likely complex, this is thought to be the reasoning behind the increase use of tobacco in those with these disorders. The increase of these nicotinic acetylcholine receptors have been implicated in the mechanism of anxiety, depression and schizophrenia. Prior work under Dr. Schulz has demonstrated that prenatal stress in mothers has the ability to increase the amount of these receptors in offspring in the hippocampus. This implies that prenatal stress has the ability to increase anxious behaviors in offspring. She has also demonstrated that dietary changes, however—such as increasing select vitamins like choline—can mitigate the intensity of these anxious behaviors. This …show more content…
