Pitt researchers challenge a decades-old assumption about brain plasticity

A new study from Pitt researchers challenges a decades-old assumption in neuroscience by showing that the brain uses distinct transmission sites - not a shared site - to achieve different types of plasticity.

Mount Sinai researchers explore new depression treatment targeting brain’s potassium channels

A mechanism involving potassium channels in the brain that control brain cell activity could provide a new and fundamentally different way of treating depression symptoms in adults with major depressive disorder, according to two complementary papers published recently by researchers at the Icahn School of Medicine at Mount Sinai.

Genetic variations in Prader-Willi syndrome offer key insights into autism and psychosis

In a comprehensive Genomic Press Invited Expert Review, researchers from the University of Haifa have synthesized cutting-edge findings on Prader-Willi syndrome (PWS), revealing how this complex neurodevelopmental disorder serves as a critical model for understanding the interplay between autism spectrum disorder (ASD) and psychotic spectrum disorders (PSD).

City size reduces obesity and impulsivity through better lifestyle and education

Researchers analyzing data from 915 U.S. cities found that both obesity and impulsivity (measured by ADHD rates) are less common in larger cities, with physical inactivity linking ADHD to obesity. Education and mental healthcare access further influence these patterns, highlighting modifiable factors for urban health.

Brain imaging study reveals the power of 'eureka moments'

Have you ever been stuck on a problem, puzzling over something for what felt like ages without getting anywhere, but then suddenly the answer came to you like a bolt from the blue?

Researchers map brain networks involved in word retrieval

How are we able to recall a word we want to say? This basic ability, called word retrieval, is often compromised in patients with brain damage. Interestingly, many patients who can name words they see, like identifying a pet in the room as a "cat", struggle with retrieving words in everyday discourse.

New insights into how the brain creates a unified visual experience

People have a lot of misconceptions about what the brain's left and right hemispheres do, but one well-known aspect of this division may be even more true than people realize: The brain not only splits up visual spatial perception-processing what's on our left in the right hemisphere and what's on our right in the left hemisphere-it takes cognitive advantage of that.

New brain network discovery could revolutionize depression diagnosis

In a comprehensive Genomic Press Commentary published today, researchers have identified what could be the first reliable biomarker for depression risk, potentially transforming how this devastating condition is identified and treated.

Why your baby’s first steps may be written in their DNA

Researchers identified 11 genetic loci linked to the age at which infants start walking, revealing that this milestone is influenced by thousands of common genetic variants. These genetic factors also correlate with brain development, cognitive traits, and neurodevelopmental conditions like ADHD.

Study links sleep apnea to damage in brain areas critical for memory

Obstructive sleep apnea, a condition that causes lower oxygen levels during sleep, is linked to degeneration of brain regions associated with memory through damage to the brain's small blood vessels, according to a study published May 7, 2025, online in Neurology, the medical journal of the American Academy of Neurology.
