Dynamic Brain Mapping and Brain-Computer Interface
Brain activity is distributed over the 3-dimensional volume and evolves in time. Mapping spatio-temporal distribution of brain activation with high spatial resolution and high temporal resolution is of great importance for understanding the brain and aiding in the clinical diagnosis and management of brain disorders. Electrophysiological source imaging from noninvasively recorded electroencephalogram (EEG) has played a significant role in advancing our ability to image brain function and dysfunction. We will discuss the principles of electrophysiological source imaging (ESI) and how AI/ML can greatly facilitate addressing technical challenges in ESI imaging, and applications to mapping epileptogenic networks using high density EEG. We will also discuss principles and state of the art of brain-computer interface (BCI) using noninvasive EEG, from which human intention is decoded using novel ML/AI algorithms. We show that human is able to control the flight of a drone and a robotic arm for reach, grasp and continuously move in 3D space, using only “thoughts” decoded from noninvasive EEG. Our results show that experience with mindful meditation can improve human’s capability for mind control, suggesting the importance of human-machine intelligence. Our recent work further highlights the advantages of utilizing transcranial focused ultrasound neuromodulation at V5 to amplify theta and alpha oscillations, thereby enhancing BCI performance for motion VEP spellers in humans.
