This project uses human brain organoids as a tool to study and treat the neural bases of neurological disorders, and epilepsy in particular. This is a cutting-edge project; the engaged student will be one of the few people in the world who will be working with these brains and record and manipulate their electrophysiological activity. The project is developed to the point where the student can begin to record from the organoids immediately.
The student will determine the electrophysiological mechanisms that underlie epilepsy in the human brain. Specifically, the student will compare the electrophysiological activity of brain organoids from healthy subjects to organoids derived from the genome of epileptic patients.
The student will introduce specific drugs that interact with specific ion channels, and determine which agent is most effective to quench epilepsy in the brain tissue of the given patient.
This approach opens a path to personalized treatments of epilepsy, and may evolve into large collaborations with the industry.
Student Learning Outcomes & Benefits
The project is highly interdisciplinary. It combines the study of developmental biology (growing brain tissue), engineering (implanting and recording from individual neurons), and science (the mechanisms underlying spilepsy). It allows the student to synthesize her/his knowledge of multiple domains or classes and put them into practical use. It also enables the student to further her/his experience with data analysis. This project is highly attractive and the student will present the results at a national conference. This shall further her/his sense of accomplishment, excitement about the project, and her/his enthusiasm for research and science.
Regarding specific learning outcomes, the student will
- Learn about a new model of the human brain---human brain organoids grown from induced pluripotent stem cells.
- Learn how to record electrophysiological activity from the organoids using implanted electrode arrays.
- Learn how to analyze the signal.
- Learn how to visualize epileptic versus normal brain activity.
- Learn how to stop epileptic activity with appropriate agents.
College of Engineering
As a Principal Investigator, I will engage the student in the following activities:
- Guide the student in performing the experiments while helping her/him to see the big picture.
- Show the student how to analyze the signals recorded from the brains, and allow her/him to write her/his own scripts that improve our current simple analyses.
- Allow the student to present results and receive feedback in our weekly lab meetings.
- Regularly talk with the student about her/his teaching/mentoring experience and how it can be made even more effective.
- Regularly discuss with the student her/his future plans and potentially serve as her/his senior thesis mentor if the student agrees so.
