A science lecturer determined to teach people about different brain regions has shaved her head during an educational video. The clip shows Nancy Kanwisher, a professor at the Massachusetts Institute of Technology, chopping at her shoulder-length bob with scissors just a few seconds into a lecture. A graduate student then uses an electronic razor to shave the rest off, with piles of hair left on a bench in front of a projector. The short video was posted on the scientist's Brain Talks website, which is designed to teach people about the different methods of studying the brain. Ms Kanwisher, 56, said: 'I thought it would be a fun way to draw attention to my site where I have posted lots of short videos talking about the cool things we have learned about the human mind and brain. 'There is a lot of silly stuff about the human mind on the web that misses out on the real science - and that is a shame because the real science is just as exciting. 'In just the last couple of decades we have discovered some truly fundamental and exciting things about the human mind and brain.' During the footage Ms Kanwisher is heard explaining: 'It is hard to tell [what the different regions are] with all this hair in the way so let's take care of that.' After the haircut the student used permanent markers to draw the different brain regions on Ms Kanwisher's bare scalp.

After the haircut a student used a permanent marker to draw the different brain regions on Ms Kanwisher's bare scalp (above) The professor introduced the 'cool part of the brain' - the cortex - before highlighting the area that specifically responds to faces. She also points out the regions that react to bodies, places and languages, as well as  one that is only used when a person is thinking about what someone else is thinking. It is not the first time the professor has played an active role in one of her educational videos. In another she allowed her brain to be zapped with transcranial magnetic stimulation - a noninvasive method used to stimulate small regions of the brain. Ms Kanwisher added: 'I hope to keep expanding the site to cover other new topics - when I think up wacky ways to dramatize science I will do them. Stay tuned!'
