Does a 14T MRI scanner make more noise than a 3T MRI scanner? Why is it easier to learn a language as a kid? Do colours appear the same to everyone? What is the impact of speaking multiple languages on the brain? Why do some people remember things better than other people? What is the effect of a visual impairment on the brain? And is there anything we can do to restore it?
