Brain rewires itself after damage or injury, life scientists discover
When the brain's primary "learning center" is damaged, complex new neural circuits arise to compensate for the lost function, say life scientists from UCLA and Australia who have pinpointed the regions of the brain involved in creating those alternate pathways — often far from the damaged site.   The research, conducted by UCLA's Michael Fanselow and Moriel Zelikowsky in collaboration with Bryce Vissel, a group leader of the neuroscience research program at Sydney's Garvan Institute of Medical Research, appears this week in the early online edition of the journal Proceedings of the National Academy of Sciences. ...

Assessment and Functional Impact of Allocentric Neglect: A Reminder from a Case Study.
We report here that SR suffers from both viewer-centered (i.e., egocentric) and object-centered (i.e., allocentric) spatial neglect. Notably, unlike most neuropsychological and functional assessments that focus on egocentric deficits, a specialized neuropsychological figurative discrimination test (the Apples test) revealed SR's allocentric neglect. Further, using assessments sensitive to detect functional deficits related to allocentric neglect, we observed SR's difficulty in reading and using clocks, reflecting his object-centered errors in these everyday activities. SR's case suggests that allocentric-specific assessmen...

P 181. Impact of offline transcranial direct current stimulation on consolidation of motor sequence learning in healthy elderly subjects
Conclusions: Offline application of anodal tDCS over M1 post training improves consolidation of motor sequence learning in elderly subjects until at least 22h post training. Further studies are needed to investigate the potential benefit of offline-tDCS in motor learning in healthy elderly and stroke patients.

The protective effect of caffeic acid on global cerebral ischemia-reperfusion injury in rats
Ischemic stroke is a major cause of death and disability all over the world. Ischemic stroke results from a temporary or permanent reduction of cerebral blood flow that leads to functional and structural damage in different brain regions. Despite decades of intense research, the beneficial treatment of stroke remains limited. In light of this, the search for effective means ameliorating cerebral ischemia-reperfusion injury (CIRI) is one of the major problems of experimental medicine and biology. Recently, the 5-Lipoxygenase (5-LO, a key enzyme metabolizing arachidonic acid to produce leukotrienes) inhibitors have been show...

Hands-Free Human-Computer Interface Based on Facial Myoelectric Pattern Recognition
Conclusion A facial movement-machine interface was developed in this study in order to help users with limited hand function manipulate electronic devices. Facial movements were detected using four EMG sensors, and five movement patterns were classified using myoelectric pattern recognition algorithms. The results from 10 able-bodied subjects show that facial movements can be detected and classified at high accuracies. The pattern-based continuous mapping between facial movements and cursor actions achieved high performance in both a typing task and a drawing task. Ethics Statement This study was approved by the Committ...

The lived experience of engaging in everyday occupations in persons with mild to moderate aphasia.
Conclusion: Aphasia can have a long-term impact on engagement in everyday occupations and participation in society, but conversely, engagement in meaningful occupations can also contribute to adaptation to disability and life changes. Implications for Rehabilitation Aphasia can have a long-term impact on engagement in everyday occupations and participation in society. Health care professionals need to determine what clients with aphasia think about their occupations and life situations in spite of difficulties they may have verbalizing their thoughts. Experiences of engaging in meaningful occupations can help clie...

A narrative analysis of a speech pathologist's work with Indigenous Australians with acquired communication disorders.
Conclusions: Individual, detailed narratives are useful in exposing the challenges and clinical reasoning behind culturally sensitive practice. Implications for Rehabilitation Speech pathologists (SPs) can learn from hearing the clinical stories of colleagues with experience of providing rehabilitation in culturally diverse contexts, as well as from ongoing training in culturally competent and safe practices. Such stories help bridge understanding from the general to the particular. SPs working with Indigenous Australians with acquired communication disorders post-stroke and brain injury may find it helpful to consider how...

Idaho mom goes the distance to help teen with scoliosis
“You want a hospital with the best technology and the best nurses and doctors in the country. You expect that, and you expect it to be clean. Boston Children’s has all of that,” says Lisa Findlay, a mom from Hayden, Idaho. “What made the difference was how much everyone loves these kids. Everyone who walked into Aaron’s room, from the surgeons to nurses’ aides to janitors and child life specialists, was on a mission to help Aaron.” From the time he was born, Aaron encountered one medical challenge after another. He was born with hypoplastic left heart syndrome (HLHS), a serious congenital heart defect. By...

Perspective of synaptic protection after post-infarction treatment with statins
Stroke is the second most common cause of death in people over 45 years of age in Colombia and is the leading cause of permanent disability worldwide. Cerebral ischemia is a stroke characterized by decreased blood flow due to the occlusion of one or more cerebral arteries, which can cause memory problems and hemiplegia or paralysis, among other impairments. The literature contains hundreds of therapies (invasive and noninvasive) that exhibit a neuroprotective effect when evaluated in animal models. However, in clinical trials, most of these drugs do not reproduce the previously demonstrated neuroprotective property, and s...

Hacking The Nervous System
(Photo: © Job Boot) One nerve connects your vital organs, sensing and shaping your health. If we learn to control it, the future of medicine will be electric.When Maria Vrind, a former gymnast from Volendam in the Netherlands, found that the only way she could put her socks on in the morning was to lie on her back with her feet in the air, she had to accept that things had reached a crisis point. “I had become so stiff I couldn’t stand up,” she says. “It was a great shock because I’m such an active person.”It was 1993. Vrind was in her late 40s and working two jobs, athletics coach and a carer for disabled ...

Can Pet Affection Improve Heart Health?
by Mimi O' Connor An energetic-looking young woman came bouncing down the aisle of the airplane so quickly that I barely had time to read the message on her T-shirt before she plopped down in the seat next to me. It read in bold letters "I LOVE ANIMALS," and underneath in smaller italics, "humans not so much." Being an animal lover myself, her shirt made me smile. I felt compelled to ask her about it. She told me that she was a veterinary medicine student and has cared for an expansive menagerie of critters since she was a little girl. My exposure to animals was modest by comparison. I've lived with and loved just two dogs...

Functional rehabilitation of upper limb apraxia in poststroke patients: study protocol for a randomized controlled trial
This study will use a two-arm, assessor-blinded, parallel, randomized controlled trial design, involving 40 patients who present a left- or right-sided unilateral vascular lesion poststroke and a clinical diagnosis of upper limb apraxia. Participants will be randomized to either a combined functional rehabilitation or a traditional health education group. The experimental group will receive an 8-week combined functional program at home, including physical and occupational therapy focused on restorative and compensatory techniques for upper limb apraxia, 3 days per week in 30-min intervention periods. The control group will...
