Making Moves to Understand Cognitive Function in the Brain

The cerebellum, a structure found in the back of the skull, is known to be important for the control of movement, while the frontal cortex is responsible for cognitive functions such as short-term memory and decision making. However, as the scientists continue to unlock the mystery of how billions of neurons in the brain interact, it is becoming more apparent that it is not that black and white

Skills-based Stroke Prevention Intervention Benefit the Hispanic Individuals, Findings

A culturally tailored program used when discharging stroke patients from the hospital helped to lower blood pressure among Hispanic individuals one year later, finds a new study led by researchers at NYU College of Global Public Health. The almost 10 mm Hg reduction in systolic blood pressure measured in this study has been linked to a nearly 40% reduction in the risk of having another stroke in previous studies.

Concussions: Insulation Around Brain Cells Disrupted

Detailed scans of concussed hockey players found that the protective fatty tissue surrounding brain cell fibers was loosened two weeks after the injury — even though the athletes felt fine and were deemed ready to return to the ice. A loosening of that insulation, called myelin, slows the transmission of electrical signals between neurons, and shows that passing a concussion test may not be a reliable indicator of whether the brain has truly healed.
