New Imaging Technique Offers Hope for Patients with Traumatic Brain Injury

Brain injuries are exceedingly complex, which makes treatment and rehabilitation difficult in many cases. Researchers at the University of Pittsburgh have reported using a new imaging technique called High-Definition Fiber Tracking (HDFT) to identify the disrupted neural pathways (paths made up of brain cells that communicate with one another) in patients with traumatic brain injury.

Body Clock Strength Impacts Bipolar Disorder

Bipolar Disorder, also known as manic–depressive disorder, is a condition characterized by alternating states of elevated energy, cognition and mood, with periods of irritable mood and depression. The extreme mood swings experienced by patients with bipolar disorder have been strongly associated with disruptions in circadian rhythms — the 24-hour cycle of biological processes that govern our day and night activity.

Lithium is one of the most common treatments for bipolar disorder. However, little research has been done to find out if and how lithium impacts the brain and peripheral body clockwork. A new study published in the open access journal PLoS ONE reveals a novel link between lithium, bipolar disorder and circadian rhythms [1].

Cellular Mechanisms of Long Term Memory Storage

Dr. Menahem Segal, head of the Laboratory of Neuronal Plasticity at the Weizmann Institute of Science in Israel, studies the neuronal basis of long term memory in the brain. Of particular interest are conditions that are associated with deterioration of memory systems, such as those occurring in Alzheimer’s disease patients and mentally retarded children.

Active Video Games May Not Increase Physical Activity in Children

A study published in the journal Pediatrics shows that children given “active” video games meant to encourage whole-body movement don’t necessarily increase physical activity.

Regular Use of High-Heeled Shoes Changes Mechanics of Walking

High-heeled shoes are a fashion statement for many women. They define the calf muscle, make legs appear longer, and cause the buttocks to protrude slightly. While most women who wear high-heeled shoes know that they’re not the most supportive footwear option, a new study shows that they have a much more profound effect than previously thought. Published in the Journal of Applied Physiology, a recent study shows that high-heeled shoes change the mechanics of walking in a habitual user, even when the user is walking barefoot [1].
