Part 3 - Phantoms In The Brain (Episode 1)

The result of this simple experiment would prove dramatic for our understanding of consciousness. Barry was able to navigate around the obstacles without tripping over a single one.

Barry has blindsight, an extremely rare condition that is as paradoxical as it sounds. People with blindsight consistently deny awareness of items in front of them, but they are capable of amazing feats, which demonstrate that, in some sense, they must be able to see them.

In another case, a man with blindsight let's call him Rick was put in front of a screen and told to guess from several options what object was on the screen.

Rick insisted that he didn't know what was there and that he was just guessing, yet he was guessing with over 90 percent accuracy. Blindsight results from damage to an area of the brain called the primary visual cortex.

This is one of the areas, as you might have guessed, responsible for vision. Damage to primary visual cortex can result in blindness — sometimes total, sometimes partial.

So how does blindsight work? The eyes receive light and convert it into information that is then passed into the brain. This information then travels through a series of pathways through the brain to eventually end up at the primary visual cortex.

For people with blindsight, this area is damaged and cannot properly process the information, so the information never makes it to conscious awareness.

But the information is still processed by other areas of the visual system that are intact, enabling people with blindsight to carry out the kind of tasks that we see in the case of Barry and Rick.

Blindsight serves as a particularly striking example of a general phenomenon, which is just how much goes on in the brain below the surface of consciousness.

This applies just as much to people without blindsight as people with it. Studies have shown that naked pictures of attractive people can draw our attention , even when we are completely unaware of them.

Other studies have demonstrated that we can correctly judge the colour of an object without any conscious awareness of it.

Blindsight has generated a lot of controversy. Some philosophers and psychologists have argued that people with blindsight might be conscious of what is in front of them after all , albeit in a vague and hard-to-describe way.

This suggestion presents a difficulty, because ascertaining whether someone is conscious of a particular thing is a complicated and highly delicate task.

There is no "test" for consciousness. You can't put a probe or a monitor next to someone's head to test whether they are conscious of something — it's a totally private experience.

We can, of course, ask them. But interpreting what people say about their own experiences can be a thorny task.

Their reports sometimes seem to indicate that they have no consciousness at all of the objects in front of them Rick once insisted that he did not believe that there really were any objects there.

Other individuals with blindsight report feeling "visual pin-pricks" or "dark shadows" indicating the tantalising possibility that they did have some conscious awareness left over.

So, what does blindsight tell us about consciousness? Exactly how you answer this question will heavily depend on which interpretation you accept.

Do you think that those who have blindsight are in some sense conscious of what is out there or not? If they're not, then blindsight provides an exciting tool that we can use to work out exactly what consciousness is for.

By looking at what the brain can do without consciousness, we can try to work out which tasks ultimately require consciousness.

From that, we may be able to work out what the evolutionary function of consciousness is, which is something that we are still relatively in the dark about.

On the other hand, if we could prove that people with blindsight are conscious of what is in front of them, this raises no less interesting and exciting questions about the limits of consciousness.

What is their consciousness actually like? How does it differ from more familiar kinds of consciousness? And precisely where in the brain does consciousness begin and end?
