5 Clinical Trials for Various Conditions
The purpose of the study is to evaluate the use of a new brain stimulation tool called transcranial direct current stimulation (tDCS). tDCS is a new technique used to stimulate the brain. The investigators believe that it may help to change brain function in individuals with anorexia nervosa. The brain stimulation occurs outside the head. The tDCS procedure involves applying a small amount of electrical current across the scalp, for a short period of time. This small electrical current is able to change the electrical activity inside areas of the brain. In the current study, the investigators will ask participants to complete computer-based brain training sessions. While participants do the brain training exercises, they will receive either real tDCS for "sham" tDCS. "Sham" tDCS means that participants might feel sensations like tingling or vibrations from the tDCS machine, but will not actually receive the electrical current. Investigators will also ask participants to complete several tests to assess changes in brain function. The information gained from this study will help investigators to understand how tDCS could be used to improve brain function and learning in individuals with anorexia nervosa.
The aim is to validate a new sham (control) method for use in transcranial direct current stimulation (tDCS) that is less discernible to participants from the real condition. Participants are often able to tell real from sham conditions. Correctly guessing real from sham undermines the integrity of evaluations of the value of tDCS as a treatment tool as responses may be in part or entirely the result of treatment expectation effects. The study will test a new sham method to reduce food craving and eating and test how much participants are able to discern it from the real or 'target' condition.
This study evaluates the application of non-invasive brain stimulation in the treatment of Mild Cognitive Impairment (MCI) in adults aged 55-85. Half of the participants will receive transcranial direct current stimulation (tDCS), while the other half will receive sham (like placebo) stimulation.
The objective of this randomized, double-blind, sham-controlled, crossover study is to evaluate the effects of transcranial electrical stimulation (tES) on complex cognitive task performance in healthy adult volunteers. The primary questions this study aims to answer are: 1. Does tES improve task performance, including speed, accuracy, and overall success, during a computerized track-and-capture task? 2. Do different stimulation targets produce differential effects on performance? 3. Are there short-term post-stimulation effects on task performance (up to 48 hours)? Participants will: 1. Complete two testing sessions under either active or sham stimulation conditions. 2. Perform a complex operational task involving dual-hand controllers while undergoing tES or sham stimulation, and immediately after. 3. Return for follow-up task performance assessments at 24 and 48 hours post-stimulation to evaluate after-effects.
