Lecture Topics Fall 2022

Lecture Topics for Fall 2022

The following lists the topics planned for each lecture. In general, the lecture notes on the course website correspond to the planned topics and should be read prior to the lecture. Therefore, assume the lecture notes are always assigned. That being said, not all topics covered in the course website lecture notes will be included in the in-person lecture. They are, however, fair game for qSets and QQs. I also provide below the recommended readings. The topics list may be modified during the semester. PN6 refers to the textbook “Neuroscience 6th edition” by Purves and colleagues.
