expect to take copious notes since exam heavily based on lectures

Readings:
reading list and readings here
background reading:

each question has several short-answer subsections
example questions provided after each lecture
old pdf answer keys from my 30-hour ugrad Systems Neuroscience course (2007) here and here
N.B.: old course covered more topics; our exam will only cover topics covered in class
Review session TBA
