Voices in the Brain: Disruption of the Default Network Linked to Hallucinations

Hearing voices that are not there was once thought to be a core symptom of schizophrenia and signify severe mental illness. It has been increasingly acknowledged that people with no other symptoms of schizophrenia or psychosis do hear voices [1]. There are several theories about what causes these auditory hallucinations. For example, there is good evidence that hearing voices can be linked to trauma [2]. Attempting to understand the phenomenon is not only scientifically interesting but also relates to how society views people with these experiences and if and how they may be treated. A search for how these experiences are associated with brain function is ongoing. New research published in the journal Human Brain Mapping suggests that the predisposition to hearing voices may relate to abnormal functioning of the brain whilst at rest [3].
