High Resolution Brain Mapping using Functional MRI


Study Goal

The goal of this study is to use high resolution functional MRI to map brain activity related to finger movements and sensations.


The purpose of this research study is to map areas of the brain related to movement of various parts of the body (hand, wrist, fingers, mouth).  We will use magnetic resonance imaging (MRI) to take a 3-D picture of your brain structure.  Brain activity will be measured in the same MRI scanner using a type of MRI called functional MRI.  This way we can locate exactly where the brain activity is occurring.  We will use functional magnetic resonance imaging to measure and locate brain activation relating to the movement, touch and position of various joints in the body.  We will also measure activity associated with imagining movement (e.g. "imagine moving a videogame joystick"), sound effects (e.g. differing musical tones) and physical touch (e.g. tactile or vibration stimulation).  We hope to use this information in future studies related to the surgical placement of BCI devices for individuals with upper limb amputation.

Inclusion Criteria:

  • Subjects must be between the ages of 18 and 65 years old.
  • Subjects must have normal or corrected to normal vision.

Exclusion Criteria: 

  • Subjects must not have a pacemaker, baclofen pump, cochlear implant or other electronic implanted device.
  • Subjects must not have a metallic implant that is unsafe for 3T MRI.
  • Female subjects of childbearing age must not be pregnant.
  • Subjects must not weigh over 300 lbs. (because of MRI risks/space).
  • Subjects must not have a history of neurologic disease, motor impairment or acute or chronic pain.
  • Subjects must not have visual impairment such that extended viewing of a computer monitor would be difficult
