Neuroscientist Michael Kilgard has found videos of leading mind and brain researchers giving lectures on their areas of interest, and created an online directory so you can view the talks at your leisure.
The speakers include language researcher Steven Pinker, memory afficianado Endel Tulving and attention pioneer Michael Posner.
This list includes almost 50 lectures in total, with topics ranging from drug addiction to vision.
Popcorn anyone?
