In a new study, investigators have uncovered both shared and distinct molecular changes across brain regions, genomic layers, cell types, and blood in individuals with post-traumatic stress disorder (PTSD) and major depressive disorder (MDD).

New research has revealed that areas of age-related damage in the brain relate to motor outcomes after a stroke—a phenomenon that may be under-recognized in stroke research.

A large study using pre-pandemic brain scans of adolescents reveals that brain wiring before COVID-19 predicted mental health outcomes during the pandemic. Adolescents with stronger connections within the brain’s “salience network,” responsible for emotion and reward processing, demonstrated greater resilience to stress and negative emotions. Conversely, weaker connections in the prefrontal cortex and other areas linked to emotional processing were associated with higher levels of stress and sadness.These findings highlight the importance of understanding individual brain differences in predicting and addressing mental health vulnerabilities during challenging times.

A team of medical researchers at the National Children’s Medical Center, Children’s Hospital, Fudan University, China, has developed a technique to freeze and thaw brain tissue without causing damage.

Singing can improve language recovery in stroke patients by repairing the brain’s language network. This positive effect is attributed to increased grey matter volume in language regions and improved connectivity within the network.

A new AI tool to more quickly and accurately classify brain tumours has been developed by researchers at The Australian National University.

An international research collaboration investigated how highly organised patterns of neural activity emerge during development and found the cortex of the brain can transform unorganised inputs into highly organized patterns of activity.

Results from a new study suggest that long-term exposure to air pollution leads to increased risk in dementia in Denmark.

A recent study published in Health Data Science reveals the significant impact of high cumulative body mass index (BMI) on brain health. The research found that high BMI is associated with smaller brain volume, larger white matter lesions, and abnormal microstructural integrity.

A team of neurosurgeons and AI specialists has found some success in restoring speech to a patient who lost the ability after a stroke.

A study published in iScience from researchers from the Ivcher Institute for Brain, Cognition, and Technology at Reichman University offers a new perspective towards the plasticity of the brain, and integration of the senses, paving the way for the enhancement of prosthetics and assistive technologies, and even our interactions with virtual and augmented realities.

Finally this week, research addresses a gap in understanding how ketamine’s impact on individual neurons leads to pervasive and profound changes in brain network function.
