Silence for thought: Special interneuron networks in the human brain

Scientists map prominent differences in the neural circuits of mice, monkeys, and human.

Researchers untangle the APOE4 gene, the most significant genetic risk factor for Alzheimer’s disease

Researchers have discovered two important novel aspects of the gene: 1) human genetic background inherited with APOE4 is unique to APOE4 patients and 2) the mechanistic defects due to APOE4 are unique to human cells.

Research reveals the pons plays a significant role in processing sad information

Researchers conducted studies to explain the neural mechanisms of the pons-corticolimbic network in perpetuating sad mood in depression.

Feelings of detachment predict worse mental health outcomes after trauma

Following trauma, feeling detached from one’s surroundings may suggest a higher risk of later developing serious mental health conditions. It’s important to screen for feeling detached to identify patients who might benefit from preventive care.

Reducing air pollution can support healthy brain development

A new study finds that having a portable air cleaner in the home can reduce the negative impacts of air pollution on brain development in children. Scientists are studying the benefits of using air filters to reduce exposure to air pollution during pre…

Muscle biopsy test for biomarker could lead to earlier diagnosis of ALS

Amyotrophic lateral sclerosis (ALS) is a progressive disease of the nervous system. It affects nerve cells in the brain and spinal cord called motor neurons. Motor neurons control muscle movement and ALS causes them to deteriorate and eventually die. T…

How the brain interprets motion while in motion

New research provides insights into a neural mechanism involved in how the brain interprets sensory information. The research may have applications for treating brain disorders and designing artificial intelligence.

Walking gives the brain a ‘step-up’ in function for some

It has long been thought that when walking is combined with a task — both suffer. Researchers have now found that this is not always the case. Some young and healthy people improve performance on cognitive tasks while walking by changing the use of ne…

Inhaled toxic particles take direct route from lungs to brain

Breathing in polluted air could lead to toxic particles being transported from lungs to brain, via the bloodstream — potentially contributing to brain disorders and neurological damage, a new study reveals.

Single brain scan can diagnose Alzheimer’s disease

A single MRI scan of the brain could be enough to diagnose Alzheimer’s disease, according to new research.
