Does neuroscience provide better explanations for behaviour than psychology? Do we produce new neurons in our adult brains? Or does this stop at a certain age? How do brain cells communicate with each other? How is a neuron made?  Do some people have stronger mental imagery than others? And does this affect how they learn? What happens in the brain when you feel ‘confused’? What causes Alzheimer’s disease? How does music affect mental health? Why is sleep so essential? Why are you grumpy after a bad night of sleep?
