![]() 2 – 5 Spatial location was considered a main clinical feature in classical psychiatry that distinguished 2 types of auditory hallucinations: outer space hallucinations, with voices heard outside the head, and inner space hallucinations, with voices heard inside the head. The detected tilt in the sulcal junction suggests deviations during early brain maturation, when the superior temporal sulcus and its anterior terminal branch appear and merge.Īuditory hallucinations are cardinal for the diagnostic of schizophrenia, 1 but their clinical characteristics, eg, clarity, familiarity, number, loudness, content, or spatial location, are variable among patients. ![]() The current results indicate that spatial location of auditory hallucinations is associated with the rTPJ anatomy, a key region of the “where” auditory pathway. In comparison to healthy subjects, opposite deviations in white matter volumes and sulcus displacements were found in patients with inner space hallucination and patients with outer space hallucination. Convergent anatomical differences were detected between the patient subgroups in the right temporoparietal junction (rTPJ). Between-group differences were then assessed using 2 complementary brain morphometry approaches: voxel-based morphometry and sulcus-based morphometry. Two homogeneous subgroups of patients were defined based on the hallucination spatial location: patients with only outer space hallucinations ( N = 12) and patients with only inner space hallucinations ( N = 15). Magnetic resonance images of 45 right-handed patients with schizophrenia and persistent auditory hallucinations and 20 healthy right-handed subjects were acquired. Brain imaging studies in schizophrenia patients with auditory hallucinations have already investigated language complexity and self-other misattribution, but the neural substrate of hallucination spatial location remains unknown. This distinction has been confirmed by recent phenomenological studies that identified 3 independent dimensions in auditory hallucinations: language complexity, self-other misattribution, and spatial location. Bleuler and Kraepelin distinguished 2 main classes of hallucinations: hallucinations heard outside the head (outer space, or external, hallucinations) and hallucinations heard inside the head (inner space, or internal, hallucinations). Auditory verbal hallucinations are a cardinal symptom of schizophrenia.
