Tracking Changes in Neural Activity from Novel Brain Stimulation
Non-invasive brain stimulation (NIBS) safely manipulates neural excitability in the brain, offering neuroscientists a powerful tool to study the human brain and clinicians a potential treatment for psychiatric and neurological disorders. NIBS methods influence the brain’s electrical activity by generating an electric field over a targeted region of the scalp. For example, directing stimulation over the motor cortex can elicit movement in a muscle of interest. The intensity of movement may reflect the integrity of the nervous system’s motor pathway but measuring electrical changes in the brain proves vital to understanding how the brain responds to stimulation. A new magnetic NIBS device developed at Berkeley requires an investigation of these electrophysiological changes. I will study our device’s effect on neural activity using electroencephalography (EEG), a non-invasive method of monitoring electrical signals in the brain. Using EEG, we hope to understand how the device modulates neural excitability and endogenous neural oscillations.
