People with schizophrenia often misinterpret what they see and experience in the world. New research provides insight into the brain mechanisms that might be responsible for this misinterpretation. The study from the Montreal Neurological Institute and Hospital – The Neuro - at McGill University and McGill University Health Centre, reveals that certain errors in visual perception in people with schizophrenia are consistent with interference or ‘noise’ in a brain signal known as a...

A new study shows that a predictive brain signal could explain why we 'hear' inner speech in our heads even in the absence of actual sound Whether you're reading the paper or thinking through your schedule for the day, chances are that you're hearing yourself speak even if you're not saying words out loud. This internal speech - the monologue you "hear" inside your head - is a ubiquitous but largely unexamined phenomenon. A new study looks at a possible brain mechanism that could explain...

Professor of neurology, physician, and author Oliver Sacks M.D. has outlined case studies of hallucinations of musical notation, and commented on the neural basis of such hallucinations, in a new paper for the neurology journal Brain. In this paper, Dr Sacks is building on work done by Dominic ffytche et al in 2000 [i], which delineates more than a dozen types of hallucinations, particularly in relation to people with Charles Bonnet syndrome (a condition that causes patients with visual...

Researchers at the University of California, San Diego School of Medicine and the VA San Diego Healthcare System have found that deficiencies in the neural processing of simple auditory tones can evolve into a cascade of dysfunctional information processing across wide swaths of the brain in patients with schizophrenia. The findings are published in the current online edition of the journal Neuroimage. Schizophrenia is a mental disorder characterized by disturbed thought processes and...

New study sheds light on OBEs in healthy and psychologically normal individuals Although out-of-body experiences (OBEs) are typically associated with migraine, epilepsy and psychopathology, they are quite common in healthy and psychologically normal individuals as well. However, they are poorly understood. A new study, published in the July 2011 issue of Elsevier's Cortex, has linked these experiences to neural instabilities in the brain's temporal lobes and to errors in the body's sense of...

Famous composer Frederic Chopin, who experienced regular hallucinations during his lifetime, most likely experienced those visions because he suffered from a form of epilepsy, a pair of Spanish researchers claim in a new study. In their investigation, Manuel Vazquez Caruncho and Francisco Branas Fernandez of the Xeral-Calde Hospital Complex in Lugo studied Chopin's letters, as well as descriptions of what he experienced written by those closest to him, including his partner, George Sand, and...

People who consume too much coffee may start hallucinating, UK researchers have announced. A Durham University team asked 200 students about their caffeine consumption habits. They reported their findings in the journal Personality and Individual Differences. People who knock back more than seven cups of coffee daily are three times more apt to have delusions than those who had only one. The academics stated, however, the discoveries do not confirm a "causal link". They also emphasized...
