Psychosis and feedback

Visible to anyone in the world

Interesting research being carried out by scientists at the University of Missouri into the origins of psychosis. Here a key area of the brain seems to be the striatum an area known to be part of a network involved with feedback. The neurotransmitter dopamine also seems to be part of the issue.

 

Researchers used fMRI technology to assess the brains of those most at risk fro psychosis and found that the striatum was not activated when the patient received feedback.

 

This research has also found increased levels of dopamine within the striatum.

Hallucinations and neuropsychology

Visible to anyone in the world

A potential result of failing eyesight is the peculiar condition, Charles Bonnet Syndrome.

This syndrome is marked by hallucinations which can be incredibly varied. For some, the hallucinations entail some rudimentary geometric shapes whereas for others it might involve sophisticated images comprised of people.

One risk according to one of Oliver Sacks' books is that this may be confused with dementia and thus Charles Bonnet Syndrome must be considered when reported hallucinations occur within a geriatric population.
What is Charles Bonnet syndrome, the eye condition that causes hallucinations?
