The photo shows a peaceful scene along a stretch of water, this is Barton Mill Pound in Cirencester. Two mallard ducks swim past. What do you see?
Mallards that you can see on the water and reflections of things on the far bank that you can’t see. Light carries information to our eyes, but the brain has to interpret it. A clever thing, the brain!
You just know, without giving it a single deliberate thought, that there’s a stone-built house on the far bank, and there are bare trees so it’s not summer time. And even the little brains of the mallards can process information in the same way. We (and they) do this all day long, every day we live, without having to take any trouble to process the information. We don’t even know how we do it! The brain has multiple layers of neurons, brightness and colour information in from the eyes to the top layer, understanding of what we see out from the bottom layer.
If you are not amazed; you should be!
A coffee is always welcome!
