Study of self-awareness in MS has implications for rehabilitation

Study of self-awareness in MS has implications for rehabilitation

A new study of self-awareness by Kessler Foundation researchers shows that persons with multiple sclerosis (MS) may be able to improve their self-awareness through task-oriented cognitive rehabilitation. The study was epublished ahead of print on July 2 in NeuroRehabilitation . Self-awareness is one’s ability to recognize cognitive problems caused by brain injury. Continue reading

Maturing brain flips function of amygdala in regulating stress hormones

Maturing brain flips function of amygdala in regulating stress hormones

In contrast to evidence that the amygdala stimulates stress responses in adults, researchers at Yerkes National Primate Research Center, Emory University have found that the amygdala has an inhibitory effect on stress hormones during the early development of nonhuman primates. The results are published this week in Journal of Neuroscience . The amygdala is a region of the brain known to be important for responses to threatening situations and learning about threats Continue reading

Taking pulse of aging of the brain

Taking pulse of aging of the brain

Researchers at the Beckman Institute at the University of Illinois at Urbana-Champaign have developed a new technique that can noninvasively image the pulse pressure and elasticity of the arteries of the brain, revealing correlations between arterial health and aging. Brain artery support, which makes up the cerebrovascular system, is crucial for healthy brain aging and preventing diseases like Alzheimer’s and other forms of dementia. Continue reading

Brain imaging shows brain differences in risk-taking teens

Brain imaging shows brain differences in risk-taking teens

According to the CDC, unintentional injuries are the leading cause of death for adolescents. Compared to the two leading causes of death for all Americans, heart disease and cancer, a pattern of questionable decision-making in dire situations comes to light in teen mortality. New research from the Center for BrainHealth at The University of Texas at Dallas investigating brain differences associated with risk-taking teens found that connections between certain brain regions are amplified in teens more prone to risk Continue reading

Bats bolster brain hypothesis, maybe technology, too

Bats bolster brain hypothesis, maybe technology, too

Amid a neuroscience debate about how people and animals focus on distinct objects within cluttered scenes, some of the newest and best evidence comes from the way bats “see” with their ears, according to a new paper in the Journal of Experimental Biology . In fact, the perception process in question could improve sonar and radar technology. Continue reading

Treating mental illness by changing memories of things past

Treating mental illness by changing memories of things past

In the novel À la recherche du temps perdu (translated into English as Remembrance of Things Past ), Marcel Proust makes a compelling case that our identities and decisions are shaped in profound and ongoing ways by our memories. Continue reading

Scientists confirm effectiveness of cognitive rehabilitation in MS

Scientists confirm effectiveness of cognitive rehabilitation in MS

Date: August 8, 2014 Source: Kessler Foundation Summary: In individuals with MS, patterns of brain activity associated with learning were maintained at six months post training, scientists report in a new article following up on a long term study. For the pilot study, participants underwent evaluation of memory performance and brain activity at baseline, immediately following memory retraining, and at 6-month followup. Results showed that the patterns of increased cerebral activation that correlated with learning were maintained at 6-month followup Continue reading

Natural light in office boosts health

Natural light in office boosts health

Office workers with more light exposure at the office had longer sleep duration, better sleep quality, more physical activity and better quality of life compared to office workers with less light exposure in the workplace, reports a new study from Northwestern Medicine and the University of Illinois at Urbana-Champaign. The study highlights the importance of exposure to natural light to employee health and the priority architectural designs of office environments should place on natural daylight exposure for workers, the study authors said. Employees with windows in the workplace received 173 percent more white light exposure during work hours and slept an average of 46 minutes more per night than employees who did not have the natural light exposure in the workplace.

Dramatic growth of grafted stem cells in rat spinal cord

Dramatic growth of grafted stem cells in rat spinal cord

Building upon previous research, scientists at the University of California, San Diego School of Medicine and Veteran’s Affairs San Diego Healthcare System report that neurons derived from human induced pluripotent stem cells (iPSC) and grafted into rats after a spinal cord injury produced cells with tens of thousands of axons extending virtually the entire length of the animals’ central nervous system. Writing in the August 7 early online edition of Neuron , lead scientist Paul Lu, PhD, of the UC San Diego Department of Neurosciences and colleagues said the human iPSC-derived axons extended through the white matter of the injury sites, frequently penetrating adjacent gray matter to form synapses with rat neurons.
