Task-relevant changes in tuning of motor cortical neurons in people with tetraplegia using an intracortical brain-computer interface

Description

Abstract:
The BrainGate team at Brown researches the use of intracortical Brain-Computer Interfaces (iBCI) to decode neural activity recorded from electrodes implanted into the motor cortex of the brain and translate it into intended movement, enabling people with disabilities to control assistive devices. Neurons in motor cortex tend to have preferred directions (PD), meaning they will fire more for intended motion in one particular direction, which can be used to infer a person’s movement intention. My project examines whether neurons try to optimize control in 2D vs 3D task-spaces by shifting their PDs to allow more information to be encoded in the relevant task-space. This is done by comparing PDs of neurons and the performances of decoders calibrated from each task.

    Each year, Brown University showcases the research of its undergraduates at the Summer Research Symposium. More than half of the student-researchers are UTRA recipients, while others receive funding from a variety of Brown-administered and national programs and fellowships and go …
