Timing of motor cortical stimulation during planar robotic training differentially impacts neuroplasticity in older adults
Neurorehabilitation efforts have focused on intense structured interventions to promote neuroplasticity because stroke is a leading cause of long-term disability world-wide. Robotic rehabilitation devices assist massed practice of upper extremity movement at high repetition rates (Lo et al., 2010; Conroy et al., 2011). They can also be used to change the learning environment, e.g., provide assistance or resistance to the motor task or train new mappings for movement to environmental effect (Krebs et al., 1998; Stein et al., 2004; MacClellan et al., 2005).

Oscillatory entrainment of the motor cortical network during motor imagery is modulated by the feedback modality
Publication date: 1 May 2015 Source:NeuroImage, Volume 111 Author(s): Mathias Vukelić , Alireza Gharabaghi Neurofeedback of self-regulated brain activity in circumscribed cortical regions is used as a novel strategy to facilitate functional restoration following stroke. Basic knowledge about its impact on motor system oscillations and functional connectivity is however scarce. Specifically, a direct comparison between different feedback modalities and their neural signatures is missing. We assessed a neurofeedback training intervention of modulating β-activity in circumscribed sensorimotor regions by kinesthetic motor ...

Positive effects of the traditional Chinese medicine MLC901 in cognitive tasks
MLC901 (NurAiDII) is used as a treatment for stroke patients. It has been shown that MLC901 improves motor and cognitive recovery in ischemic and traumatic brain‐injured rodents. The present study seeks to delineate cognitive effects induced by MLC901 in normal, noninjured mice. To this end, the behaviors of vehicle‐ and MLC901‐treated C57BL/6 mice in hippocampus‐dependent (passive avoidance, Morris water maze) and hippocampus‐independent (novel object recognition) cognitive tasks are compared. The potential influence of the compound on the anxiety level and nycthemeral rhythm of mice is also assessed. In additio...

Neuromechanical Principles Underlying Movement Modularity and Their Implications for Rehabilitation
Publication date: 8 April 2015 Source:Neuron, Volume 86, Issue 1 Author(s): Lena H. Ting , Hillel J. Chiel , Randy D. Trumbower , Jessica L. Allen , J. Lucas McKay , Madeleine E. Hackney , Trisha M. Kesar Neuromechanical principles define the properties and problems that shape neural solutions for movement. Although the theoretical and experimental evidence is debated, we present arguments for consistent structures in motor patterns, i.e., motor modules, that are neuromechanical solutions for movement particular to an individual and shaped by evolutionary, developmental, and learning processes. As a consequence, ...

Thyroid Hormone Signaling: Contribution to Neural Function, Cognition, and Relationship to Nicotine
Publication date: Available online 5 September 2015 Source:Neuroscience & Biobehavioral Reviews Author(s): Prescott T. Leach, Thomas J. Gould Cigarette smoking is common despite its adverse effects on health, such as cardiovascular disease and stroke. Understanding the mechanisms that contribute to the addictive properties of nicotine makes it possible to target them to prevent the initiation of smoking behavior and/or increase the chance of successful quit attempts. While highly addictive, nicotine is not generally considered to be as reinforcing as other drugs of abuse. There are likely other mechanisms at wo...

Rhynchophylline Protects Against the Amyloid β-Induced Increase of Spontaneous Discharges in the Hippocampal CA1 Region of Rats.
Abstract Accumulated soluble amyloid β (Aβ)-induced aberrant neuronal network activity has been recognized as a key causative factor leading to cognitive deficits which are the most outstanding characteristic of Alzheimer's disease (AD). As an important structure associated with learning and memory, the hippocampus is one of the brain regions that are impaired very early in AD, and the hippocampal CA1 region is selectively vulnerable to soluble Aβ oligomers. Our recent study showed that soluble Aβ1-42 oligomers induced hyperactivity and perturbed the firing patterns in hippocampal neurons. Rhynchophylline (RIN...

Linking Essential Tremor to the Cerebellum: Clinical Evidence.
Abstract Essential tremor (ET) might be a family of diseases unified by the presence of kinetic tremor, but also showing etiological, pathological, and clinical heterogeneity. In this review, we will describe the most significant clinical evidence, which suggests that ET is linked to the cerebellum. Data for this review were identified by searching PUBMED (January 1966 to May 2015) crossing the terms "essential tremor" (ET) and "cerebellum," which yielded 201 entries, 11 of which included the term "cerebellum" in the article title. This was supplemented by articles in the author's files that pertained to this topi...

Electroencephalographic neurofeedback: Level of evidence in mental and brain disorders and suggestions for good clinical practice
Publication date: Available online 6 November 2015 Source:Neurophysiologie Clinique/Clinical Neurophysiology Author(s): J.-A. Micoulaud-Franchi, A. McGonigal, R. Lopez, C. Daudet, I. Kotwas, F. Bartolomei The technique of electroencephalographic neurofeedback (EEG NF) emerged in the 1970s and is a technique that measures a subject's EEG signal, processes it in real time, extracts a parameter of interest and presents this information in visual or auditory form. The goal is to effectuate a behavioural modification by modulating brain activity. The EEG NF opens new therapeutic possibilities in the fields of psychiat...

High voltage electric potentials to enhance brain-derived neurotrophic factor levels in the brain.
Authors: Yanamoto H, Nakajo Y, Kataoka H, Iihara K Abstract Development of a safe method to increase brain-derived neurotrophic factor (BDNF) levels in the brain is expected to enhance learning and memory, induce tolerance to cerebral infarction or tolerance to depressive state, improve glucose metabolism, and suppress appetite and body weight. We have shown that repetitive applications of high-voltage electric potential (HELP) to the body increase BDNF levels in the brain, improving learning and memory in mice. Here, we investigated the effects of HELP treatment for a chronic period on the BDNF levels in the mouse...

A brain-computer interface to support functional recovery.
Authors: Kjaer TW, Sørensen HB Abstract Brain-computer interfaces (BCI) register changes in brain activity and utilize this to control computers. The most widely used method is based on registration of electrical signals from the cerebral cortex using extracranially placed electrodes also called electroencephalography (EEG). The features extracted from the EEG may, besides controlling the computer, also be fed back to the patient for instance as visual input. This facilitates a learning process. BCI allow us to utilize brain activity in the rehabilitation of patients after stroke. The activity of the cerebral cort...

Neuroscience meets salivary bioscience: An integrative perspective.
Advances in salivary bioscience enable unique opportunities to explore individual differences in biological mechanisms related to learning and memory, psychiatric disorders, and more recently neurodegenerative diseases, neurotrauma/stroke, pain, and sleep. Sampling oral fluid is not only minimally invasive, but specimens can be collected easily and quickly in clinical and field settings. Salivary analytes allow neuroscientists to index endocrine, autonomic, immune, metabolic, and inflammatory processes within close proximity of discrete behavioral, biological, and social events, which is particularly important to advancing...
