The arcuate fasciculus in auditory-verbal hallucinations: A meta-analysis of diffusion-tensor-imaging studies

Frontal fasciculi and psychotic symptoms in antipsychotic-naive patients with schizophrenia before and after 6 weeks of selective dopamine D2/3 receptor blockade

“…Curiously, a recent meta-analysis found that FA in left AF was negatively correlated with auditory verbal hallucinations. 39 These discrepancies in findings may be explained by the fact that our patients were antipsychotic-naive and that PANSS positive symptoms cover several items other than auditory verbal hallucinations.…”

Paracingulate sulcus morphology and hallucinations in clinical and non-clinical groups

“…In this case, the PCS morphological differences we detect would simply be markers of the underlying cause of the associated cognitive variability. This too offers a focus for further research, with existing structural connectivity studies of hallucinations broadly supportive of such an explanation 44,45 . Furthermore, Vercammen et al 46 found evidence of reduced functional connectivity between the left temporoparietal junction and bilateral ACC associated with more severe AVHs in patients with schizophrenia.…”

White Matter Differences Among Adolescents Reporting Psychotic Experiences

“…There are also several reports (including a meta-analysis) showing increased FA in the arcuate fasciculus in patients with auditory hallucinations compared with controls. [66][67][68][69] The findings of increased FA in genetic high-risk, sibling, and ultra-high-risk samples 58,[70][71][72] suggest that increased FA may reflect a vulnerability to developing psychosis. Our findings add to the literature in this area by demonstrating that increased FA in frontotemporal and frontoparietal projections is related to the propensity to experience auditory hallucinations in young people who do not have a psychotic disorder.…”
