A 2026 eLife study recorded 3,881 lateral orbitofrontal cortex units in rats and found that prior cocaine use made the OFC over-distinguish task positions that controls treated as functionally equivalent. The headline result was not gross task failure: cocaine-experienced rats still performed the odor task, but their OFC ensembles showed higher S1-vs.-S2 decoding than sucrose …
A 2026 double-blind randomized controlled trial by Kappes et al. in Psychopharmacology found something the smart-drug users likely wouldn’t have predicted: a single 30 mg dose of methylphenidate reduced dishonest misreporting on a die-rolling task from ~22% of trials in the placebo arm to ~6% (in the methylphenidate arm).1 Atomoxetine, a noradrenergic comparator, had no …
Binge-eating disorder (BED), characterized by recurrent episodes of overeating without compensatory behaviors, is a significant global health concern. Lisdexamfetamine dimesylate (LDX), the only drug approved for moderate to severe BED, is showing promise not just in reducing episodes but also in altering brain function in ways previously not fully understood. Through a groundbreaking study, researchers …
The journey to overcome addiction is fraught with challenges, not least due to the limited options available for pharmacological intervention. In recent research, the focus has shifted toward understanding the role of glutamate, a key neurotransmitter in the brain, in the development and persistence of addictive behaviors. One compound, CNQX, which antagonizes certain glutamate receptors, …
In the quest to understand the intricate links between our dietary habits and mental health, a recent study leveraging data from the National Health and Nutrition Examination Survey (NHANES) 2017-2018 offers new insights into how caffeine consumption correlates with depression. This comprehensive analysis reveals that moderate caffeine intake might have a protective effect against depression, …
Coffee, one of the world’s most consumed beverages, is often lauded for its ability to enhance alertness and cognitive performance. Recent studies utilizing advanced neuroimaging techniques like resting-state functional magnetic resonance imaging (fMRI) have begun to unravel the intricate ways in which coffee, and its key component caffeine, modulate brain activity. This exploration into the …
Tobacco use is a complex behavior influenced by both environmental factors and genetic predispositions. A recent study leveraging the UCLA ATLAS biobank explored the genetic underpinnings of Tobacco Use Disorder (TUD) and its systemic health effects using a Polygenic Score (PGS). Highlights: Genetic Underpinnings of Tobacco Use: The study used a European ancestry-derived PGS to …
