Lecture 1 – What's in your head?

Your brain may look like a big walnut, but it has the ability to create an almost unlimited stream of images, thoughts, memories and dreams. Undoubtedly the most complex material in the universe, and yet it's just a collection of simple cells.

Join Bruce Hood as he gets under your skull and takes a peek inside. What do brainwaves look like? How fast is a neuron? Why does your brain create its own version of reality?

Bruce uses technology to measure brain activity and follow eye movement, build a virtual brain out of audience volunteers and play some guessing games with your mind. In the process, he shows how everything you perceive is just an interpretation of the nerve impulses that your brain receives – which isn't really that much.

Ultimately, we are all experts at filling in the blanks.
