Study shows degeneration of corpus callosum in stroke patients with impaired hand movement

The structure of the corpus callosum, a thick band of nerve fibres that connects the two halves of the brain with each other and in this way enables the rapid exchange of information between the left and right hemispheres, plays an important role in the regaining of motor skills following a stroke. A study currently published in the journal Human Brain Mapping has shown that in stroke patients with particularly severely impaired hand movement, this communication channel between the two brain hemispheres in particular was badly damaged.

Genetic basis of human cortical regionalization similar to patterns found in other mammals, MRI study affirms

A new study using magnetic resonance imaging data of 406 adult human twins affirms the long-standing idea that the genetic basis of human cortical regionalization - the organization of the outer brain into specific functional areas - is similar to and consistent with patterns found in other mammals, indicating a common conservation mechanism in evolution.

Study uses MRI to evaluate cardiovascular risk in WTC first responders

In the first study using magnetic resonance imaging (MRI) to evaluate cardiovascular risk in World Trade Center (WTC) first responders, researchers from Mount Sinai School of Medicine have found that the responders who experienced high levels of exposure to the initial dust cloud on September 11, 2001, demonstrate high-risk features of atherosclerosis.

Head hits appear to cause brain injury among high school players

The brain scans of high school football and hockey players showed subtle injury -- even if they did not suffer a concussion - after taking routine hits to the head during the normal course of play, according to a University of Rochester Medical Center study.

Study: Primary visual cortex is modulated only by attention

In everyday life, attention and awareness appear tightly interwoven. Attending to the scissors on the rinumber of behavioural observations have recently led scientists to postulate that attention and awareness are fundamentally different processes and not necessarily connected.ght side of your desk, you become aware of their attributes, for example the red handles. Vice versa, the red handles could attract your attention to the scissors.

Vegetative patients could be contacted using simple, cheap and portable technique – EEG

Scientists from the UK and Belgium have found a way to communicate with brain damaged patients who appear to be in a vegetative state. Writing in The Lancet medical journal they describe how they measured electrical activity in the brain to detect consciousness. The technique, known as EEG or electroencephalogram, is painless and involves attaching electrodes to the head.

Experimental drug selectively destroys blood supply of fat tissue and decreases body fat

Obese rhesus monkeys lost on average 11 percent of their body weight after four weeks of treatment with an experimental drug that selectively destroys the blood supply of fat tissue, a research team led by scientists at The University of Texas MD Anderson Cancer Center reports in Science Translational Medicine.

Simple portable test can diagnose 'vegetative' patients with consciousness

The Coma Science Group, led by Dr Steven Laureys, has developed, along with its partners in London, Ontario, (Canada) and Cambridge (England), a portable test which will permit a simpler and less expensive diagnosis of 'vegetative' patients who still have consciousness, despite the fact that they do not have the means to express it.

Study: Children with autism have more prefrontal brain neurons

In a small, preliminary study that included 13 male children, those with autism had an average 67 percent more prefrontal brain neurons and larger than average brain weight, than children without autism, according to a study in the Nov. 9 issue of JAMA.

Study finds spinal bleeding in young children with abusive head trauma

A new study found that spinal bleeding is found often in young children who are victims of abusive trauma. The findings support performing complete spine imaging for children undergoing brain magnetic resonance imaging (MRI) for moderate or severe traumatic brain injury and suggest a pathway for distinguishing between abusive and accidental injury.

Ocrelizumab drug holds promise for multiple sclerosis

An experimental drug called Ocrelizumab has shown promise in a Phase 2 clinical trial involving 220 people with multiple sclerosis (MS), an often debilitating, chronic autoimmune disease that affects an increasing number of people in North America.

MIT develops new software to speed up MRI scans

Magnetic resonance imaging (MRI) devices can scan the inside of the body in intricate detail, allowing clinicians to spot even the earliest signs of cancer or other abnormalities. But they can be a long and uncomfortable experience for patients, requiring them to lie still in the machine for up to 45 minutes.

Hippocampus supports both recollection and familiarity memories

Human memory has historically defied precise scientific description, its biological functions broadly but imperfectly defined in psychological terms. In a pair of papers published in the November 2 issue of The Journal of Neuroscience, researchers at the University of California, San Diego report a new methodology that more deeply parses how and where certain types of memories are processed in the brain, and challenges earlier assumptions about the role of the hippocampus.
