Scientists have discovered that insulin works directly with the brain's dopamine system to suppress the urge to overeat. Disrupting this biological link leads to persistent, compulsive food-seeking despite negative health consequences.

Men convicted of sexually sadistic crimes possess increased brain tissue in areas related to empathy and visual processing. These anatomical differences provide a rare biological glimpse into an extreme psychiatric condition.

A new mouse study published in the Journal of Psychopharmacology provides evidence that psilocybin selectively enhances the brain's ability to rewire itself. The research suggests that optimizing specific doses could help tailor treatments for different psychiatric symptoms.

Researchers have mapped a pathway connecting infant screen time to teenage anxiety. The study associates early screen exposure with accelerated brain network maturation, which predicts more hesitant decision-making in childhood and greater anxiety in adolescence.

Narcissists might not just be stubborn—their brains might be wired to ignore failure. New research shows that individuals with grandiose narcissism exhibit a blunted neural response to their own mistakes, preventing them from self-correcting.

A new review in Nature Reviews Neurology warns that falling vaccination rates are fueling a resurgence of measles and polio. This trend threatens to inflict severe, lifelong brain and spinal cord damage on a generation of unprotected children.

You might not consciously tell the difference between diet and regular drinks, but your neurons can. Research indicates that the brain generates distinct, stronger signals for sweeteners like stevia compared to sugar.

A new study reveals how a liver enzyme shores up the blood-brain barrier. Blocking a specific vessel protein replicated the cognitive benefits of exercise in aging mice and Alzheimer’s models.

New research shows that while impulsivity and neuroticism both increase the risk of teen alcohol use, they stem from almost entirely different brain networks. This highlights how multiple biological pathways can lead to risky behavior.

Researchers have identified a distinct structural signature for insight. The findings indicate that reduced connectivity in the brain's language networks may actually help facilitate sudden creative breakthroughs.

A new study reveals that mild electrical stimulation to the prefrontal cortex changes how lonely people rate negative social scenes. The findings suggest loneliness creates a mismatch between physiological reactions and conscious feelings.

New findings published in Translational Psychiatry show that responders to the drug escitalopram start with a larger left hippocampus. As symptoms improve, the volume of the right hippocampus increases.

Scientists have found evidence that LSD inhibits status epilepticus and mortality in mice. The preliminary research suggests the drug works by desynchronizing brain activity.

New research published in The Journal of Neuroscience suggests breathing acts as a pacemaker for memory. The study found that successful retrieval is linked to the respiratory cycle, synchronizing brain patterns needed to remember.

A new study finds that children exposed to violence show increased activity in the insula when seeing or hearing their parents. This suggests trauma changes how the developing brain processes caregiver signals.
