Scientists at Bangor University have discovered a patient who appears to possess a "sixth sense" that allows him to recognise sad faces.

The 52-year-old "patient X" suffered two strokes which damaged the brain areas which process visual signals.

Although he cannot see, researchers found that that the patient was able to identify angry or happy human faces.

Scans showed that when the man looked at faces with emotion, another part of his brain, the amygdala, was activated.

The small almond-shaped structure is known to respond to non-verbal signs of anger, defensiveness, avoidance and fear.

The results of the study are published in the online edition of Nature Neuroscience on Sunday.

Dr Alan Pegna of the school of psychology at the University of Wales, Bangor, led the research team with colleagues in north Wales and Geneva University Hospital.

They found that when "patient X" was shown images of shapes like circles and squares, he was only able to make wild guesses about what they were.

Nor was he able to identify the sex of "deadpan" male and female faces with any degree of success, or tell the difference between "normal" and jumbled faces.

But when the patient was asked to identify angry or happy human faces, he did so with an accuracy of 59% - significantly higher than would be expected by chance.

Behavioural scientists

There was a similar response when he was asked to distinguish between sad and happy, or fearful and happy, faces.

But pictures of animals which appeared threatening or non-threatening did not give the same kind of results.

Scientists were able to establish that emotion displayed on a human face is registered in an area other than the visual cortex.

The area involved was identified as the right amygdala, an almond-shape structure situated deep within the brain's temporal lobe.

I believe in 6th sense. When a human is born missing one of the 5, he either is strong on all 4 or develops the six sense (whatever this is).

6th sense? No, I don't think so. If you loose a sense, you don't win a 6th sense imo. My father lost the smell sense in a motorbike accident a long time ago and he hasn't got any "6th sense". Nevertheless, anything is possible...

You must be the skeptic of skeptics Mark. http://www.tombraiderforums.com/images/smilies/tongue.gif
Here we have a scientific study (which skeptics often demand) telling you that this man was able to identify the emotions on the faces of people and he is BLIND. But no, there's no 6th sense. He's just a good guesser eh? And the brain scans showing the active amygdala are false somehow. http://www.tombraiderforums.com/images/smilies/c-2.gif

Not exceptic, but realistic. I'm one of those people who says "if I don't see it, I don't believe it".

he did so with an accuracy of 59%SO, he didn't make it perfect. If they give you two options (angry or happy), you have lots of possibilities to get with the correct one (50% of possibilities).

I definitely belive it. Some people have a more keen sixth sense than others.

Not that I can feel it 100% of the times, but I can often feel when someone is looking at me. Then I turn around quickly and see a person looking at me.

Me scary. http://www.tombraiderforums.com/images/smilies/clown.gif

Some sort of natural instinct - and also the fact that, when someone approaches you, the air around you changes; and intuitively and subconsciously you can sense that.

Yes, I wouldn`t call it a sixth sense... (pretty boring one if you could only sense people watching you)

...But I read in National Geographics or some other serious sience magazine... Most people got around 50/50 on scoring if someone else was watching them. But other scored near 100%...

But about your quote. So, he scored over 50% and for scientific purposes that's a statistical signifant figure. Probabitlity would dictate he would get 50%, he did better than probability which (quite apart from the scans of the amygdala) indicates something else (other than the five accepted senses) is at work. 6 follows 5, therefor you could legitimately call it a 6th sense.

I think the term 6th sense is restrictive however (and suspect you and others are simply uncomfortable with the term because of the connotations it carries). We have many senses that operate on various levels. Some of us are more aware of such senses and are able to utilise them or at the least make note of them. None of this is other-worldly, but rather, part of the natural functioning of the human mind.

just hav to tell this to u...
i can feel danger. this happened like a year ago.
i was at home, playin with my guinea pigs n then i suddenly felt SO hot.. i was almost sweatin. my mom was there too n she didnt feel anything. anyway, i felt so awkward i had to go outside to the balcony to cool myself. then i heard ambulance. i went inside n was like "hey mom, i culd feel the danger! hehe..." but the next day my mom callled me (i was at my dad's house). my friend was at a hospital. a car had crashed into her at the moment i felt the hotness. she broke her leg etc. but she's fine now i guess. not too close with her anymore..
so, that was kinda weird.

For example, when you are dreaming, the mind is creating images - we are used to this and it doesn't impress us, yet it's an ability that surpasses the limits of everyday experience.

Concerning the topic subject - I knew a blind girl some years ago, who could understand if the other opposite her was happy or sad and also what colour your hair was with just touching it, and she could also distinguish the notes (money) by just touching them. The most impressive thing about her case was that she was born blind, therefore she had no experience of images and colours the conventional way.

I knew a blind woman once too. She could tell the time just by listening to the chimes on the clock. It was amazing! http://www.tombraiderforums.com/images/smilies/mischievous.gif :D
