A single, low dose of  lysergic acid diethylamide (LSD) can increase reward-related brain activity, according to new research published in Neuropsychopharmacology. The study indicates that the psychedelic drug alters neuropsychological processes that tend to be blunted in patients with depression. New research published in Experimental Neurology provides some initial evidence that the psychedelic substance known as LSD has nootropic properties. The study found that LSD increased markers of neuroplasticity in human brain organoids, increased novelty preference in rats, and improved memory performance in humans. Scientists have taken an important first step into studying the effects of the psychedelic drug psilocybin — the active substance in “magic” mushrooms — at a cellular and genetic level. Their findings, published in Scientific Reports, indicate that a single dose of psilocybin produces a long-lasting antidepressant-like effect in flies.

New psychology findings offer evidence that the food we eat has a direct influence on our mental health. The study, published in the British Journal of Nutrition, found that eating more fruit predicted fewer depression symptoms and greater psychological well-being while eating more savory snacks predicted increased anxiety. New findings suggest that allostatic load mediates the association between early life adversity and global cognition, as well as executive function. This research was published in the scientific journal Psychoneuroendocrinology. According to new research published in Nature Human Behaviour, slowing in response time can begin as early as age 20. However, this change can be explained by increased caution in decision making and slowing of non-decisional processes, as opposed to a slowing in mental speed. Slowing of mental speed was observed only after age 60. New research published in the Proceedings of the National Academy of Sciences provides evidence that voters in Georgia who embraced Donald Trump’s claims of widespread election fraud were less likely to cast their ballot in a pivotal runoff election.
