NCT ID: NCT05892224 Recruiting - Obesity Clinical Trials

Study on Brain Function of Obesity Classification

Start date: January 1, 2022
Phase:
Study type: Observational

The purpose of this study was to investigate the differences and similarities of brain function in patients with four subtypes of obesity, and the relationship between brain function changes and complications after weight loss and metabolic improvement. 120 patients with obesity and 30 healthy individuals with normal BMI were enrolled.

NCT ID: NCT04723823 Recruiting - Clinical trials for Functional Neuroimaging

Sensorimotor Imaging for Brain-Computer Interfaces

Start date: August 8, 2019
Phase: N/A
Study type: Interventional

The investigators will use fMRI to map movement activity in motor and somatosensory cortex using enriched imagery in people with chronic tetraplegia. The investigators expect that somatotopic organization of movement activity will be preserved in people with upper limb impairments, which can be quantified using the strength, area, and location of sensorimotor activity. Accurate mapping of the motor and somatosensory cortices using covert stimuli will help guide brain-computer interface (BCI) electrode design and placement. Moreover, these advanced mapping procedures will provide new insights into the functional interactions between sensory and motor areas of the brain after injury or disease.
