Sleep deprivation disrupts brain regions that prevent unwanted memories

The link between poor sleep and mental health problems could be related to deficits in brain regions that keep unwanted thoughts out of mind, according to research from the University of East Anglia (UEA).

Structural brain differences in adolescents may play a role in early initiation of substance use

A study of nearly 10,000 adolescents funded by the National Institutes of Health (NIH) has identified distinct differences in the brain structures of those who used substances before age 15 compared to those who did not.

Brain's dual role in processing touch and hearing revealed

Ludwig van Beethoven began to lose his hearing at age 28 and was deaf by age 44. While the cause of his hearing loss remains a topic of scientific debate and ongoing revision, one thing is clear: Despite his hearing loss, Beethoven never ceased to compose music, likely because he was able to sense the vibrations of musical instruments and "hear" music through the sense of touch, researchers believe.

Chemogenetic activation reveals male-female differences in stress resistance neural circuits

Subtle activation of a small subset of neurons in one region of the brain can make male mice resilient to, and even reverse, the detrimental effects of chronic stress. The same is true for female mice, but in a totally different region of the brain.

Study reveals link between dyslexia genes and brain structure

Dyslexia is a common learning difficulty in which genes often play a role. How do genes associated with dyslexia relate to brain structure in the general population? In a large-scale study published in Science Advances, a team of scientists led by the Max Planck Institute for Psycholinguistics in Nijmegen found that genetic variants that increase the chance of dyslexia were associated with differences in brain areas involved in motor coordination, vision, and language.

Study uncovers brain mechanism behind empathetic responses

A specific brain mechanism modulates how animals respond empathetically to others' emotions. This is the latest finding from the research unit Genetics of Cognition, led by Francesco Papaleo, Principal Investigator at the Istituto Italiano di Tecnologia (IIT - Italian Institute of Technology) and affiliated with IRCCS Ospedale Policlinico San Martino in Genova.

Frontotemporal dementia disrupts empathy for pain, study reveals

Study reveals diminished brain activity related to empathy for pain in individuals with behavioral variant frontotemporal dementia (bvFTD), using task-based fMRI. Findings show a stark reduction in neural responses tied to affective empathy, highlighting early bvFTD impacts on social cognition.
