With around 100 billion neurons transmitting and processing information second by second, the brain is possibly the most complex organic form in the universe. Our brains are pre-programmed when we’re born but they’re also shaped by our experiences. Since deaf people’s experience is different to hearing people’s, does that mean we think differently? This week we’re taking a journey into the workings of the deaf brain – conducting fascinating tests and talking to experts in the field about their latest research. We find out if BSL is processed in a different way to hearing language. We explore how our brains can be flexible and test whether deaf people have different visual perception, different sensory perception and even an entirely different way of remembering. And we’ll be asking - is there is such a thing as a deaf brain?
