UCLA researchers develop improved technique for creating brain tissue from stem cells
UCLA researchers have developed an improved technique for creating simplified human brain tissue from stem cells. Because these so-called “mini brain organoids” mimic human brains in how they grow and develop, they’re vital to studying complex neurological diseases. (more…)
Research finds rapid brain ‘remapping’ in patients years after stroke
By examining the sense of touch in stroke patients, a University of Delaware cognitive psychologist has found evidence that the brains of these individuals may be highly plastic even years after being damaged.
The research is published in the March 6 edition of the journal Current Biology, in an article written by Jared Medina, assistant professor of psychology at UD, and Brenda Rapp of Johns Hopkins University’s Department of Cognitive Science. The findings, which are focused on patients who lost the sense of touch in their hands after a stroke, also have potential implications for other impairments caused by brain damage, Medina said.

Bedside Early-Warning System from IBM and Excel Medical Electronics Can Analyze Large Amounts of Data in Real Time to Predict Dangerous Changes in a Patient’s Condition
Armonk, N.Y. and Los Angeles, CA – 26 Mar 2013: IBM, and Excel Medical Electronics (EME) are collaborating with the UCLA Department of Neurosurgery in a study to test the effectiveness of a real-time alarm intended to predict rising brain pressure in patients with traumatic brain injuries. The experimental system uses big data analytics software developed by IBM Research and EME that analyzes in real-time streams of vital signs continuously collected from the bedside monitor to spot subtle changes in the patient’s pulse, blood and intracranial pressure, heart activity, and respiration, signaling that dangerous high-risk increases in brain pressure are on the way.

Mild cooling of the brain after a head injury prevents the later development of epileptic seizures, according to an animal study reported this month in the Annals of Neurology.
Epilepsy can result from genetics or brain damage. Traumatic head injury is the leading cause of acquired epilepsy in young adults. It is often difficult to manage with antiepileptic drugs. The mechanisms behind the onset of epileptic seizures after brain injury are not known . There is currently no treatment to cure it, prevent it, or even limit its severity. (more…)
Women suffering from sleep apnea have, on the whole, a higher degree of brain damage than men with the disorder, according to a first-of-its-kind study conducted by researchers at the UCLA School of Nursing. The findings are reported in the December issue of the peer-reviewed journal SLEEP. (more…)
GAINESVILLE, Fla. — By analyzing the genes of bacteria, University of Florida researchers have moved a step closer to pinpointing how two brain disorders common in small-breed dogs occur.
The researchers found that the bacteria, known as Mycoplasma canis, invade dog’s cells and suppress their immune system responses. (more…)
Researchers at the UCL Institute of Neurology have found that giving the drug rotigotine as a skin patch can improve inattention in some stroke patients.
Hemi-spatial neglect, a severe and common form of inattention that can be caused by brain damage following a stroke, is one of the most debilitating symptoms, frequently preventing patients from living independently. When the right side of the brain has suffered damage, the patient may have little awareness of their left-hand side and have poor memory of objects that they have seen, leaving them inattentive and forgetful. Currently there are few treatment options. (more…)
*Research into aphasia – the inability to speak or write well-formulated sentences and words – is strong at the UA. Researchers have received $2 million toward the study of the condition.*
The National Institutes of Health have awarded the University of Arizona’s Aphasia Research Project in the department of speech, language and hearing sciences a $2 million grant to research communication impairments in adults who have suffered brain injury.
Aphasia – the inability to speak or write well-formulated sentences and words – is a common result of a stroke or a traumatic brain injury such as the one suffered by Rep. Gabrielle Giffords, who was shot in the head earlier this year. The bullet damaged regions of the brain that are critical for language and control of the right side of the body. (more…)
