Video Lectures

Planned is a series of 21 video lectures. Of these, 11 are now posted as “beta” versions.

The videos are available in a playlist on YouTube here.  I like watching lectures on YouTube because I can increase the playback speed when needed  :-)

You can view or download the lectures here. Links for downloading individual lectures can be found below.

Thanks for viewing! Please add your comments or corrections in the comment field of the YouTube pages or on the video page, or email to fred.sigworth@yale.edu
