Intravenous PEP-1-GDNF is protective after focal cerebral ischemia in rats
Publication date: 23 March 2016 Source:Neuroscience Letters, Volume 617 Author(s): Yaning Liu, Shangwu Wang, Shijian Luo, Zhendong Li, Fengyin Liang, Yanan Zhu, Zhong Pei, Ruxun Huang Glial cell line-derived neurotrophic factor (GDNF) is a potential therapeutic protein on a variety of central nervous system diseases including ischemic stroke. However, GDNF is a large molecule that cannot cross the blood–brain barrier (BBB), which is still intact in the early hours after stroke when neural rescue is possible. PEP-1 protein transduction domain can deliver protein cargo across the cell membrane and the BBB. In the...

Impaired implicit learning and feedback processing after stroke
Publication date: 9 February 2016 Source:Neuroscience, Volume 314 Author(s): J.M. Lam, C. Globas, J.A. Hosp, H.-O. Karnath, T. Wächter, A.R. Luft The ability to learn is assumed to support successful recovery and rehabilitation therapy after stroke. Hence, learning impairments may reduce the recovery potential. Here, the hypothesis is tested that stroke survivors have deficits in feedback-driven implicit learning. Stroke survivors (n =30) and healthy age-matched control subjects (n =21) learned a probabilistic classification task with brain activation measured using functional magnetic resonance imaging in a subse...

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...

Probable Nootropic-induced Psychiatric Adverse Effects: A Series of Four Cases
Conclusion Healthcare providers in general, and specifically those in the mental health and substance abuse fields, should keep in mind that nootropic use is an under recognized and evolving problem. Nootropic use should be considered in cases where there are sudden or unexplained exacerbations of psychiatric symptoms in patients who have been stable and medication adherent. It is also important to remember that most nootropics are not detected on standard drug toxicology screening tests. We have very little clinical information on how nootropics may interact with psychotropics (or other medications) and potentially cause ...

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...

Learning from brain control: clinical application of brain –computer interfaces
In conclusion, clinical application of brain machine interfaces in well-defined and circumscribed neurological disorders have demonstrated surprisingly positive effects. The application of BCIs to psychiatric and clinical–psychological problems, however, at present did not result in substantial improvement of complex behavioral disord ers.

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...

Motor imagery-based skill acquisition disrupted following rTMS of the inferior parietal lobule.
Abstract Motor imagery (MI), the mental rehearsal of motor tasks, has promise as a therapy in post-stroke rehabilitation. The potential effectiveness of MI is attributed to the facilitation of plasticity in numerous brain regions akin to those recruited for physical practice. It is suggested, however, that MI relies more heavily on regions commonly affected post-stroke, including left hemisphere parietal regions involved in visuospatial processes. However, the impact of parietal damage on MI-based skill acquisition that underlies rehabilitation remains unclear. Here, we examine the contribution of the left inferio...

The presence of a single-nucleotide polymorphism in the BDNF gene affects the rate of locomotor adaptation after stroke.
Abstract Induction of neural plasticity through motor learning has been demonstrated in animals and humans. Brain-derived neurotrophic factor (BDNF), a member of the neurotrophin family of growth factors, is thought to play an integral role in modulation of central nervous system plasticity during learning and motor skill recovery. Thirty percent of humans possess a single-nucleotide polymorphism on the BDNF gene (Val66Met), which has been linked to decreased activity-dependent release of BDNF. Presence of the polymorphism has been associated with altered cortical activation, short-term plasticity and altered skil...

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...
