The way the human brain works is still a mystery. Even neuro-scientists can only guess at the complexities of memory, sleep, motivation and creativity. But we humans have always been impatient to understand more. All of our moods and behaviours are affected by neurotransmitters, the brain’s chemical messengers. Research now suggests that food can affect the levels of these neurotransmitters. It could mean that what we eat may make our brains perform better. Food For Thought explores this idea and attempts to unravel some age-old mysteries. How can stress be good for us? What can we do to help improve our memory? Why is sleep so important? What can we learn from robots? And most interestingly, is there anything we can eat to help us learn? Firefighters, a jazz pianist and a Memory Champion all come together to try to solve one of mankind’s most intriguing questions. Can we improve the performance of our brain?
