1 Reduced Neuronal Activity in Language-Related Regions After Transcranial Magnetic Stimulation Therapy for Auditory Verbal Hallucinations  Jochen Kindler, Philipp Homan, Kay Jann, Andrea Federspiel, Richard Flury, Martinus Hauf, Werner Strik, Thomas Dierks, Daniela Hubl  Biological Psychiatry  Volume 73, Issue 6, Pages (March 2013) DOI: /j.biopsych Copyright © 2013 Society of Biological Psychiatry Terms and Conditions

2 Figure 1 Cerebral blood flow, z-transformed, as measured by arterial spin labeling, paired t test, p < .001, cluster size >20. Yellow areas show a significant decrease in the cerebral blood flow for the transcranial magnetic stimulation (TMS) treatment group between pre- and post-TMS measurements in three regions of interest: the left primary auditory cortex, Broca's area, and the cingulate gyrus. The corresponding cluster information is provided in Table 2. L, left. Biological Psychiatry  , DOI: ( /j.biopsych ) Copyright © 2013 Society of Biological Psychiatry Terms and Conditions

3 Figure 2 Mean cerebral blood flow (CBF), z-transformed, extracted for regions of interest before and after transcranial magnetic stimulation (TMS) therapy. CBF was reduced after TMS in the primary auditory cortex of 14 of 15 individuals, in Broca's area for 13 of 15, and in the cingulate gyrus of 13 of 15. Pre, before treatment; post, after treatment.

4 Figure 3 Correlation of psychopathology and cerebral blood flow (CBF) in the primary auditory cortex. Decrease in psychopathology (Δ Psychotic Symptom Rating Scale [PsyRats]) and decrease in cerebral blood flow (Δ CBF, z-transformed) correlated significantly in the primary auditory cortex (Pearson's r = .77, p = .001).
