There were some things by Robert Winston on the BBC - The Human Mind.
You might be able to get stuff if you sign up to the open university website somehow (not sure), but it was on DVD as well (so I'll let you figure out how to access that - maybe a dvd library in you university?). Anyway, there are some synopses on the different episodes on their website. http://www.open.edu/openlearn/whats-on/ou-on-the-bbc-the-human-mind
He also wrote a great book called 'The human mind and how to make the most of it'. Or you could try Ramachandran for some interesting light reading on the subject.
edit, I realise these aren't lectures, but they are still relevant even if they are for lay people. They've stuck with me and helped in my psychology course even though it was years later.
