The neurobiological bases underlying the generation of auditory hallucinations, a distressing and paradigmatic symptom of schizophrenia, are still unknown in spite of in-depth phenomenological descriptions. This work aims to make a critical review of the latest published literature in recent years, focusing on functional neuroimaging studies (PET, SPECT, fMRI) of auditory hallucinations. Thus, the studies are classified according to whether they are sensory activation, trait and state. The two… 

Social and personality variables related to the origin of auditory hallucinations

Hallucinations represent one of the most interesting and relevant symptoms in Psychopathology today. Although mainly associated with psychotic disorders, they are also present in an important range

A Neurocognitive Approach to the Study of Private Speech

The evolution of private speech research is described, which goes from classic traditions as the naturalistic and referential paradigms to the neurocognitive approach, and the advances and new challenges in the field are discussed.

Fluordeoxyglucose-PET study in first-episode schizophrenic patients during the hallucinatory state, after remission and during linguistic–auditory activation

The findings show a different pattern of regional cerebral glucose metabolism between AVH and physiological auditory activation, which does not support the hypothesis that AVH in acute schizophrenic patients reflects an abnormal activation of auditory–linguistic pathways, but does suggest that cortical regions implicated in the generation of inner speech could be involved.

Estudio comparativo de las publicaciones realizadas sobre psicosis en las revistas de psicología y psiquiatría españolas

The objective of this study was to examine the article production on psychosis from the main spanish journals of psychology and psychiatry, as well as to make comparisons among them. 16 journals of

Cortical Auditory Functional Activation By Cortico-Striato-Thalamo-Cortical Circuits

The neuroanatomical component involved in the activation of the auditory cortex is characterized and a mechanism to generate intrinsic perception of sound that may be responsible for auditory hallucinations is characterized to elucidate insight on the biological basis of psychotic behavior.

Anomalías de la estructura y función del hipocampo en la esquizofrenia en relación a los déficits de memoria declarativa

La literatura cientifica demuestra diferentes anomalias cerebrales estructurales y funcionales en la esquizofrenia. El proposito de la presente tesis ha sido investigar las anomalias en la



A functional neuroanatomy of hallucinations in schizophrenia

A group study of five patients with classic auditory verbal hallucinations despite medication, demonstrating activations in subcortical nuclei (thalamic, stri-atal), limbic structures (especially hippocampus), and paralimbic regions (parahippocampal and cingulate gyri, as well as orbito-frontal cortex).

Neuroimaging of hallucinations: a review of the literature

Subvocal activity and auditory hallucinations: clues for behavioral treatments?

The data concerning the temporal relationship between EMG activity and self- report of hallucinations were inconclusive, however, one of the experimental conditions (humming a single note softly) reduced the self-report of hallucinations by 59 percent and increased EMG amplitude over baseline levels.

Functional anatomy of auditory verbal imagery in schizophrenic patients with auditory hallucinations.

Patients with schizophrenia who were prone to auditory hallucinations show attenuated activation when processing inner speech in areas implicated in verbal self-monitoring.

Auditory hallucinations and smaller superior temporal gyral volume in schizophrenia.

The authors' MRI study of young schizophrenic patients demonstrates smaller volume of the superior temporal gyrus and of the left amygdala, which is not accounted for by smaller size of the overall brain or temporal lobe.
