Abstract:
Auditory hallucinations represent a major symptom in schizophrenia, and the present article reviews recent research with a focus on cognitive and brain markers. Auditory hallucinations are described in a neurocognitive model that sees such experiences as initiated from temporal lobe hyper-activation, not inhibited due to frontal lobe hypo-activation. It is proposed that these patterns of brain activation are mediated by abnormalities of the neurotransmitter glutamate. A new way of collecting symptom data on-line is suggested, based on iPhone app-technology.
