In this episode of WaterCooler Neuroscience, we discuss Wilf's first experimental chapter of his thesis. This is when a scientist prepares an experiment and in their dissertation will write a chapter to explain and describe that experiment to other scientists. This experiment is looking at how the brain can decide to inhibit or 'turn off' regions that are competing with what we want to be doing. In reality, the brain can't turn anything off, it is more like putting a state where it is just ticking over but ready to go if it needs to. Wilf talks about his experience of designing the experiment while Jordana Adler is the host and brings her insight from the world of neurofeedback.
