Incremental learning of Chinese orthography: ERP indicators of animated and static stroke displays on character form and meaning acquisition
We examined the hypothesis that encoding Chinese characters through stroke-by-stroke animation produces orthographic learning that is different from conventional static displays. We used behavioral responses and ERPs to index the incremental learning that occurs of character forms, and the attention allocation to dynamic vs. static encodings. Adult, native English speakers learned form-meaning associations for characters displayed either statically or dynamically while ERPs were recorded. During learning, in both conditions, the P600 component decreased over exposures, indexing incremental and episodic learning of characte...

Spatial cognitive rehabilitation and motor recovery after stroke
Purpose of review: Stroke rehabilitation needs to take major steps forward to reduce functional disability for survivors. In this article, we suggest that spatial retraining might greatly increase the efficiency and efficacy of motor rehabilitation, directly addressing the burden and cost of paralysis after stroke. Recent findings: Combining motor and cognitive treatment may be practical, as well as addressing the needs after moderate-to-severe stroke. Spatial neglect could suppress motor recovery and reduce motor learning, even when patients receive appropriate rehabilitation to build strength, dexterity, and endurance. S...

Executive dysfunction post-stroke: an insight into the perspectives of physiotherapists.
Conclusions: Current results demonstrate that ED has negative implications for physiotherapy rehabilitation post-stroke. Although further interdisciplinary research is warranted, the present results suggest that physiotherapists should be aware of the presence of ED in people post-stroke and develop strategies to minimise the impact of ED on physiotherapy rehabilitation. Implications for Rehabilitation Physiotherapists report a lack of knowledge of ED post-stroke and a requirement for future learning and training regarding the optimal management of people with ED undergoing physiotherapy rehabilitation post-stroke. ED has ...

Using hormetic strategies to improve ischemic preconditioning and postconditioning against stroke.
Authors: Zhao H, Joo S, Xie W, Ji X Abstract Both ischemic preconditioning (IPreC) and ischemic postconditioning (IPostC) trigger endogenous neuroprotective mechanisms in cerebral ischemia. IPreC is defined as a brief ischemia that protects against a subsequent severe ischemia, while IPostC refers to a series of brief cerebral blood vessel occlusions performed at reperfusion following an ischemic event. Hormesis describes a biphasic dose-response relationship in toxicology, where a low dose of toxicant stimulates and a high dose inhibits biological responses. In general, any minor stress will stimulate a biological...

Myasthenia gravis as a 'stroke mimic' - it's all in the history.
Abstract An 85-year-old man presented to hospital as an emergency having difficulties with swallowing and speech. In the emergency department, he was assessed as having acute onset dysphagia and dysarthria in keeping with an acute stroke. Subsequently, it became apparent that although the symptoms were indeed of relatively acute onset, there was a clear description by the patient of fatigability and diurnal variation, prompting a working clinical diagnosis of myasthenia gravis. The patient followed a turbulent clinical course, and interpretation of investigation results proved not to be straightforward in the acut...

Brain-Machine Interfaces In Neurorehabilitation of Stroke.
Abstract Stroke is among the leading causes of long-term disabilities leaving an increasing number of people with cognitive, affective and motor impairments depending on assistance in their daily life. While function after stroke can significantly improve in the first weeks and months, further recovery is often slow or non-existent in the more severe cases encompassing 30-50% of all stroke victims. The neurobiological mechanisms underlying recovery in those patients are incompletely understood. However, recent studies demonstrated the brain's remarkable capacity for functional and structural plasticity and recovery ...

Neural substrates underlying stimulation-enhanced motor skill learning after stroke
Motor skill learning is one of the key components of motor function recovery after stroke, especially recovery driven by neurorehabilitation. Transcranial direct current stimulation can enhance neurorehabilitation and motor skill learning in stroke patients. However, the neural mechanisms underlying the retention of stimulation-enhanced motor skill learning involving a paretic upper limb have not been resolved. These neural substrates were explored by means of functional magnetic resonance imaging. Nineteen chronic hemiparetic stroke patients participated in a double-blind, cross-over randomized, sham-controlled experiment...

Recombinant Human Erythropoietin Improves the Neurofunctional Recovery of Rats Following Traumatic Brain Injury via an Increase in Circulating Endothelial Progenitor Cells
Abstract Previous studies show that circulating endothelial progenitor cells (EPCs) promote angiogenesis, which is a process associated with improved recovery in animal models of traumatic brain injury (TBI), and that recombinant human erythropoietin (rhEPO) plays a protective role following stroke. Thus, it was hypothesized that rhEPO would enhance recovery following brain injury in a rat model of TBI via an increase in the mobilization of EPCs and, subsequently, in angiogenesis. Flow cytometry assays using CD34- and CD133-specific antibodies were utilized to identify alterations in EPC levels, CD31 and CD34 ant...

Vascular safety of brain plasticity induction via transcranial direct currents
Experience alters the strength of neuronal connections as a fundamental feature of brain physiology. This process, termed neuroplasticity, appears crucially involved in cognitive processes such as learning, memory formation, and adaptive behavior. Neuroplasticity is increasingly implicated in not only a number of neurologic diseases, but also in restitution after brain injury. Noninvasive brain stimulation can induce and modulate neuroplasticity in humans.1 In accordance with the functional relevance of neuroplasticity, noninvasive brain stimulation not only modulates psychological processes and behavior in healthy humans,...

Ipsilateral hippocampal atrophy is associated with long‐term memory dysfunction after ischemic stroke in young adults
Abstract Memory impairment after stroke in young adults is poorly understood. In elderly stroke survivors memory impairments and the concomitant loss of hippocampal volume are usually explained by coexisting neurodegenerative disease (e.g., amyloid pathology) in interaction with stroke. However, neurodegenerative disease, such as amyloid pathology, is generally absent at young age. Accumulating evidence suggests that infarction itself may cause secondary neurodegeneration in remote areas. Therefore, we investigated the relation between long‐term memory performance and hippocampal volume in young patients with first‐eve...

Compensatory Motor Network Connectivity is Associated with Motor Sequence Learning after Subcortical Stroke.
Abstract Following stroke, functional networks reorganize and the brain demonstrates widespread alterations in cortical activity. Implicit motor learning is preserved after stroke. However the manner in which brain reorganization occurs, and how it supports behaviour within the damaged brain remains unclear. In this functional magnetic resonance imaging (fMRI) study, we evaluated whole brain patterns of functional connectivity during the performance of an implicit tracking task at baseline and retention, following 5 days of practice. Following motor practice, a significant difference in connectivity within a motor...

Brain plasticity and rehabilitation in stroke patients.
Abstract In recent years, our understanding of motor learning, neuroplasticity and functional recovery after the occurrence of brain lesion has grown significantly. Novel findings in basic neuroscience have provided an impetus for research in motor rehabilitation. The brain reveals a spectrum of intrinsic capacities to react as a highly dynamic system which can change the properties of its neural circuits. This brain plasticity can lead to an extreme degree of spontaneous recovery and rehabilitative training may modify and boost the neuronal plasticity processes. Animal studies have extended these findings, provid...
