Human Cognition During Surgery: Stimulation-based and Cholinergic Modulation

This is a research study to determine how COBENFY KarXT (FDA approved), a drug which has been approved for treatment of certain disorders, affects brain activity and cognitive tasks which may be regulated by the cholinergic system. This study aims to answer: 1) how cholinergic circuitries act during task performance in humans, and 2) develop a better understanding of how cognitive control interacts with learning, memory and decision making in the setting of cholinergic manipulation. Participants will complete a single treatment arm, regardless of which surgical procedure they are to receive. An anesthesiologist or other clinical staff will administer either the drug or the saline at a critical point which addresses the research questions, prior to patient surgery. This will be either with the drug, or the placebo pill. Half of the participants will be randomized to receive the drug, and the other half of these the placebo. Participants will be unaware whether the actual drug has been received. Essential tremor patients who participate will complete a cognitive task during an awake surgery. Epilepsy patients who participate will have a resting state recording during the procedure from the deep cortical layers of the brain. A probe will be used during the surgery to measure the effects of this drug and other procedures of the study on the cholinergic system. This probe is the clinical probe known as the AlphaOmega, which is FDA approved for standard of care procedures. Researchers will compare the brain activity between treatment arms to determine what brain activity changes based on the cholinergic manipulation.

EFFECT OF PERCEPTUAL-MOTOR TRAINING ON COGNITIVE FUNCTIONS, MOTOR ABILITIES AND QUALITY OF LIFE IN CHILDREN WITH ATTENTION DEFICIT HYPERACTIVE DISORDER

This study aims to Determine the effect of perceptual-motor training on: cognitive functions, motor abilities, and quality of life in ADHD children.

Telerehab Exerbrain: Bridging Physical and Cognitive Therapy in Stroke

The goal of this clinical trial is to learn if a web-based exercise and cognitive training (physical-cognitive) program works to improve movements and brain function in adults with long-term stroke. It will also learn whether the program is safe and enjoyable. The main questions it aims to answer are: Does the program improve walking, balance, strength, and reduce fall risk? Does the program improve cognitive skills such as memory, attention, and problem-solving? Researchers will compare the online exercise-and-cognitive training program to usual care to see if the program leads to greater improvements. Participants will: * Be randomly assigned to either the online training group or the usual care group * If in the training group, complete the home-based program for 12 weeks. * Take part in physical and cognitive tests before and after the program
