What happens in your brain when you receive compliments? And what’s going on in your mind when you watch your football team win a match? Does the brain respond differently when recalling music, compared to listening to it? All these questions, and more, have been posed in our Big Brain Competition…
Coinciding with the Museum’s Brain Diaries exhibition, the Wellcome Centre for Integrative Neuroimaging is inviting you to ask your own question about the brain to be in with a chance to have it tested by neuroscientists using Oxford’s state-of-the art Magnetic Resonance Imaging (MRI) scanner.
The advanced MRI scanner at the John Radcliffe Hospital in Oxford is one of the strongest in the world. It allows scientists to carry out functional MRI (fMRI) scans to see the brain in action. This mind-blowing procedure can reveal how the brain changes when learning a new skill or how it compensates when someone recovers from brain damage. It can also reveal which areas are used when people speak, move or laugh, to give just a few examples.
Functional MRI shows when a brain area is more active by detecting the changes in blood oxygen levels and blood flow that happen in response to neural activity. The technique can be used to produce activation maps showing which parts of the brain are involved in a particular mental process.
The scientist behind the Big Brain Competition is Dr Stuart Clare, whose research involves pushing the technological boundaries of the fMRI technique to reveal new insights about how the brain functions normally and how it is affected by disease. There is still so much that the fMRI scans can bring to light, so Stuart is asking you for ideas!
Over several years of inviting people in to see the beautiful pictures that our MRI scanner can produce, I’ve been fascinated by the questions they have about the brain and whether you can see this thing or that thing in our fMRI scans. With this competition we want to give people the unique access to our scanner and the chance to try an idea out for themselves.
When coming up with an idea for investigation there are a few practical things to bear in mind. Any activity has to be something people can do when lying down in the scanner and it has to be clear when they start and stop doing the activity. But Stuart is very open to ideas for experiments that they haven’t come across before – something that scientists really don’t already know the answer to.
The animation below explains how fMRI works and what it can do. So take a look, think up an experiment of your own and enter your idea via this form. The best one will be put into action by the research team and you will be able to watch the scans take place at the John Radcliffe Hospital yourself!
