Tutorial: Brain-Computer Interfaces: Fundamentals to Future Technologies

Fueled by recent major investments, brain computer interfaces (BCIs) stand to revolutionize the treatment of neurological conditions, and in the future, the human experience. This tutorial will highlight key challenges in the realization of implantable BCIs such as closedloop operation, miniaturization, and scale. We will start by covering fundamental circuit building blocks and their interactions with electrodes, signals, and tissues. We will then go through an example of how to minimize the volume of a wireless implant.
