Abstract

Purpose of Review

Auditory verbal hallucinations (AVH) are a common experience for people diagnosed with psychosis spectrum disorders, often leading to distress and disability. The purpose here is to describe four common phenomenological features of AVH (negativity of content, memory, inner speech/self-monitoring, and spatial location), and review their associated neural mechanisms.

Recent Findings

Diverse phenomenological qualities of AVH have been found to be related to differing brain regions. Negative content of AVH is associated with the right Broca’s area and increased amygdala activation, whereas the hippocampus has been associated with memory/thought intrusions. AVH characteristic of inner speech is associated with self-monitoring networks. Lastly, spatial location of AVH is associated with auditory processing regions of the brain, including the dorsal stream.

Summary

The vast heterogeneity of AVH suggests different neurobiological and neurocognitive underpinnings associated with the various phenomenological expressions of the experience. More imaging research is needed to understand the complexity of AVH.
