In Hearing, episode one of The Science of the Senses, finding the answer to that question will take us on a journey through the ear, into the brain and right into the heart of the human psyche.

In The Science of the Senses: Touch we will take a journey through the skin, into the subcutaneous world of our sensory receptors and up into the brain as we explore the hidden language of our most essential sense.

In this episode of The Science of the Senses, we explore how smell combines with taste, somewhere in our brain, to create the perception of flavour. Most people wrongly assume that taste dominates. But what actually allows us to differentiate one food from another beyond the basics of sweet, sour, salty, savory and bitter, is the aroma.

This episode takes viewers on a fascinating tour of our visual world, from the moment light enters our eyes, to the way this information is transformed into electrical impulses and decoded by our brain - the domain of "visual perception". The act of "seeing" takes an immense amount of brainpower, more than 65% of the brain's neural pathways.
