Mapping the Brain

From early research into how different areas of the brain function to President Barack Obama's announcement in 2013 of a one hundred million dollar brain mapping project, Martin Sixsmith examines the impact of neuroscience on what we know about the way we think, feel and act.

He undergoes transmagnetic cranial stimulation to map the workings of his brain and he looks down a microscope at the Oxford Brain Bank to see what individual brain cells can tell us.

He listens to the chattering of neurons communicating with each other through a single wire implanted in a rat's brain and finds out why London cabbies have larger hippocampi than the rest of us.
