Performance Enhancement and Non-Invasive Brain Stimulation

2015-07-16 11:08:23 | BioPortfolio


A promising form of enhancing brain function non-invasively involves stimulating the brain using weak magnetic or electric currents. This method is becoming increasingly popular in both clinical and commercial circles; a number of portable, at-home devices are available on the commercial market for personal use. In this study, the investigators aim to determine factors associated with the enhancement of cognitive and motor learning following transcranial direct-current stimulation in healthy young adults. Understanding how participants respond to brain stimulation is critical to maximizing the effectiveness of stimulation and determining its potential as a performance-enhancing aid for mental tasks. Future developments of this study may also inform the capacity of brain stimulation to act as non-drug alternative to treatment for cognitive decline.

Efficacy and Mechanisms of Transcranial Direct Current Stimulation (tDCS) - Effects on Working Memory in Schizophrenia

Impairments of cognition are a core, severely disabling feature of schizophrenia leading to poor long-term outcome with no established treatment available. Particularly impaired executive...

Augmentation of Working Memory Training With Transcranial Direct Current Stimulation in Patients With Schizophrenia

Cognitive impairment is a core symptom of schizophrenia and is in a large part responsible for the poor psychosocial outcome of the disorder. The use of non-invasive brain stimulation tech...

The primary aim of this study is to assess the magnitude of transcranial direct current stimulation (tDCS) -induced cognitive and functional change in patients with mild traumatic brain in...

High Definition Transcranial Direct Current Stimulation (HD-tDCS) in Patients With Mild Cognitive Impairment

The study aimed to investigate whether high definition transcranial direct current stimulation (HD-tDCS) could benefit global cognitive function and sub-domains of cognition (visual/verbal...

Central Executive Training (CET) for ADHD

The goal of the current project is to assess the efficacy of Central Executive Training (CET) for youth with ADHD. CET is a new, computerized training intervention that targets specific co...

Exploring the effects of Transcranial Direct Current Stimulation over the prefrontal cortex on working memory: a cluster analysis approach.

The interest in the use of anodal transcranial direct current stimulation (tDCS) for the enhancement of cognitive functioning has increased significantly in recent years. However, the efficacy of this...

A Prospective Open-Label Pilot Study of Transcranial Direct Current Stimulation in High-Functioning Autistic Patients with a Dysexecutive Syndrome.

Executive functions (EF) are often impaired in autism spectrum disorder (ASD). Such dysfunctions are associated with anxiety, depression, and a lack of autonomy. Transcranial direct current stimulatio...

Effects of Transcranial Direct Current Stimulation on Episodic Memory in Older Adults: A Meta-analysis.

In the last two decades, the number of intervention studies using transcranial direct current stimulation (tDCS) has grown enormously. Though some studies have shown positive influences on episodic me...

Preliminary findings of four-week, task-based anodal prefrontal cortex transcranial direct current stimulation transferring to other cognitive improvements in schizophrenia.

Most transcranial Direct Current Stimulation (tDCS) trials of schizophrenia administer few sessions and do not assess transfer effects to other cognitive domains. In a randomized, double-blind, sham-c...

The efficacy of transcranial direct current stimulation and transcranial magnetic stimulation for chronic orofacial pain: A systematic review.

Transcranial Direct Current Stimulation (tDCS) and Transcranial Magnetic Stimulation (TMS) have been described as promising alternatives to treat different pain syndromes. This study evaluated the eff...

Medical and Biotech [MESH] Definitions

A technique of brain electric stimulation therapy which uses constant, low current delivered via ELECTRODES placed on various locations on the scalp.

A set of cognitive functions that controls complex, goal-directed thought and behavior. Executive function involves multiple domains, such as CONCEPT FORMATION, goal management, cognitive flexibility, INHIBITION control, and WORKING MEMORY. Impaired executive function is seen in a range of disorders, e.g., SCHIZOPHRENIA; and ADHD.

The electrical response evoked in a muscle or motor nerve by electrical or magnetic stimulation. Common methods of stimulation are by transcranial electrical and TRANSCRANIAL MAGNETIC STIMULATION. It is often used for monitoring during neurosurgery.

Application of electric current in treatment without the generation of perceptible heat. It includes electric stimulation of nerves or muscles, passage of current into the body, or use of interrupted current of low intensity to raise the threshold of the skin to pain.

Measurable changes in activities in the CEREBRAL CORTEX upon a stimulation. A change in cortical excitability as measured by various techniques (e.g., TRANSCRANIAL MAGNETIC STIMULATION) is associated with brain disorders.
