We have two brains?

We’ve all tried at some point to lose weight and one of the many ways in which we do this is by cutting down our portion size. Science tells us that a routine of eating large portions stretches our stomach, causing us to require larger portions more regularly in order to satisfy our hunger. In addition, we’re aware that signalling cells, neurons, line our stomach and relay information about hunger and fullness to the brain. Previously it was believed that detection of how stretched our stomach is, is the most important factor in determining fullness, however research is now revealing that the neuronal network in the stomach has a larger part to play than we initially thought.

Michael Mosley from the BBC visited the London Science Museum to swallow a camera that would take photos of his digestive tract, whilst it was digesting. He presents a TV programme to be aired tomorrow at 21:00 BST on BBC4 titled Guts: The Strange and Mysterious World of the Human Stomach where he explores the complexity of our second brain – the stomach, an organ which we are only realising can control not just our hunger but also our moods and emotions. Check out the TV programme and if you miss it we always have BBC iPlayer! Also check out his article on BBC News website - !
