A brain glitch may explain why some people hear voices

Summary:
    New research suggests that auditory hallucinations in schizophrenia may come from a brain glitch that confuses inner thoughts for external voices. Normally, the brain predicts the sound of its own inner speech and tones down its response. But in people hearing voices, brain activity ramps up instead, as if the voice belongs to someone else. The discovery could help scientists develop early warning signs for psychosis.

Auditory and even visual hallucinations are also a product of extreme sleep deprivation, whether the lack of rest is drug induced or otherwise.

Those go away with adequate rest in the latter case.

Yes, but there a cause is easy to identify - sleep deprivation - in the case of schizophrenia, that cause is not present.

Maybe one of them isn't getting enough sleep.

Huh?

[Smokin Joe]

Huh?

Multiple personalities. One of them not getting enough sleep? Get it?

I do not rule out the possibility that some people perceive things that other people do not. It doesn't necessarily mean they are crazy.

My dog would often see something in the corner of a room or something... Nothing there, but he's got his 'kill you' growl on... Cats too - sometimes they see things I cannot. Freaks me out when that is happening. Spooky, right?

Vergette had a patient years ago that was legally blind. (He could see an area about 3-4 inches in diameter out of his right eye.) he had both visual and auditory hallucinations at the same time. As far as I recall they swere never able to get his meds balanced.

Exactly. If you could hear or see wavelengths others could not, be it seeing into infrared, or hearing extremely high pitches, others might think you odd at best when you said 'that's hot' or 'that bearing is going bad--Can't you hear that?'.

Only repeated success at perceptions that were useful (given the opportunity) would redeem you in the eyes of most skeptics, but it would be explained as a 'knack'. A local welder could armor oil tools with brazed on carbide. Oil tool companies tried to duplicate his technique and failed. He claimed the trick was in pre-heating the surface, and they tried to get all that right with pyrometers and IR thermometers and such. He just said if it looked right he'd start to apply the coating, if it didn't he'd have another cup of coffee and a cigarette and then take another look.
They never were able to duplicate his results--close, but not quite as good.
He took his secret to his grave.
I honestly think he could, knowingly or otherwise, see when the temperature was right, even though it looked the same to everyone else.
