Episode 4 brings you the first of Wilf's episodes that were designed from conception by himself. His work leads him to try to understand how inhibition works when we have multiple competing senses active but now we are going further. This episode explores how the brain uses inhibition when it both knows something is coming up and when it doesn't. Wilf's research lead him away from using EEG and fMRI but instead to using a machine called magnetoencephalography or MEG. Wilf talks about why he had to train with this machine and what new data this brought to his expanding collection of research.
