Optogenetics, chemogenetics, and biosensors for neural circuit research

Genetically encoded tools for neuroscience enable precise observation and manipulation of defined neural cell types, in behaving animals. This course provides both breadth and depth in the theoretical and practical application of these tools across a variety of classes including experimental designs, and with an emphasis on hands-on experience.

After completing this course, a student should expect to be knowledgeable about a wide range of molecular tools, have experience with multiplexed read/write experimental design, understand how to integrate optical hardware with rodent behavior, and appreciate nuances between 1-photon and 2 photon implementations. Interpretation and data analysis are integrated across the course.

The course will comprise keynote lectures, hands-on expert workshops in experimental sessions and data analysis. Keynote lecturers will provide an introduction to their respective fields and exciting recent findings, while expert workshops will be given by a selected set of instructors. Instructors will work with the students prior to the course to design and plan their experiments in detail.

Each student will have an opportunity to present his/her work in a poster session, and an interactive journal club will provide the students with an opportunity to present and discuss the seminal studies that have shaped modern neuroscience through the introduction of novel techniques. Following the success of a pilot session held in the previous course, we will also hold semi-formal discussions with directors and instructors about career development, scientific “soft skills” and science communication.
