How does our brain create a 3D world? Is this possible with just one eye? How is it possible that we can hear either ‘green needle’ or ‘brainstorm’ whilst the audio fragment remains the same? Why do brain tissues have different colours? How is it that some people see an object as blue, while others say that same object is green? Do we really have a reptile brain, a mammal brain, and a human brain inside our heads? What is the effect of a visual impairment on the brain? And is there anything we can do to restore it? When are we able to solve MS? Can a brain scan show whether people are already producing their language response while their conversation partner is still speaking? Is dopamine good for you and serotonin bad? How do brain cells communicate with each other?
