Formal thought disorder (FTD) refers to a psychopathological dimension characterized by disorganized and incoherent speech. Whether symptoms of FTD arise from aberrant processing in language-related regions or more general cognitive networks, however, remains debated. Here, we addressed this question by a quantitative meta-analysis of published functional neuroimaging studies on FTD. The revised Activation Likelihood Estimation (ALE) algorithm was used to test for convergent aberrant activation changes in 18 studies (30 experiments) investigating FTD, of which 17 studies comprised schizophrenia patients and one study healthy subjects administered to S-ketamine. Additionally, we analyzed task-dependent and task-independent (resting-state) functional connectivity (FC) of brain regions showing convergence in activation changes. Subsequent functional characterization was performed for the initial clusters and the delineated connectivity networks by reference to the BrainMap database. Consistent activation changes were found in the left superior temporal gyrus (STG) and two regions within the left posterior middle temporal gyrus (p-MTG), ventrally (vp-MTG) and dorsally (dp-MTG). Functional characterization revealed a prominent functional association of ensuing clusters from our ALE meta-analysis with language and speech processing, as well as auditory perception in STG and with social cognition in dp-MTG. FC analysis identified task-dependent and task-independent networks for all three seed regions, which were mainly related to language and speech processing, but showed additional involvement in higher order cognitive functions. Our findings suggest that FTD is mainly characterized by abnormal activation in brain regions of the left hemisphere that are associated with language and speech processing, but also extend to higher order cognitive functions.

“…Two regions corresponded to the bilateral seeds on the fusiform gyrus. Similar to the analysis of FG1, two clusters were located bilaterally in the early visual cortex posterior to the seed overlapping with areas V3v, hV4 [19] and V4lp [20], and one cluster represented the primary and partially secondary visual cortex V1 and V2 [21] of both sides. On the right hemisphere one cluster was located on the superior occipital gyrus and intraparietal sulcus overlapping with hIP3 [23].…”

Purpose: To investigate the distribution of co-activation patterns of the recently identified ventral visual areas FG1 and FG2 of the posterior fusiform gyrus using the novel meta-analytic approach PaMiNI (Pattern Mining in NeuroImaging). Materials and Methods: All neuroimaging experiments reporting activation foci within FG1 or FG2 were retrieved from the BrainMap database. The stereotaxic activation foci in standard reference space were analyzed with PaMiNI. Here, Gaussian mixture modeling was applied to the stereotaxic coordinates of all foci to identify the underlying brain regions of each dataset. Then, association analysis was performed to reveal frequent co-activations across the modeled brain regions. Results: Co-activation patterns of FG1 were mainly found within the visual system, i.?e. in early visual areas, and were symmetrically distributed across both hemispheres. FG2 features several extra-visual co-activations, mainly to inferior frontal, premotor and parietal regions. Furthermore, the co-activations of FG2 showed clear lateralization to the left FG2. Conclusion: FG1 shows characteristics of an intermediate visual area between the early ventral visual cortex and the category-specific higher-order areas. Co-activation patterns of FG2 indicate that FG2 is a higher-order visual area that probably corresponds to the posterior fusiform face area and partly the visual word-form area. Key points ??Co-activation patterns of areas FG1 and FG2 were analyzed with PaMiNI. ??FG1 features mainly symmetric co-activations to areas of the visual system. ??FG2 shows several extra-visual co-activations, which are left-lateralized. ??FG1 corresponds to a hierarchically intermediate, FG2 to a higher-order visual area. ??The PaMiNI approach is extended to seed-specific mapping of co-activation patterns.

“…S3]; Table ). Strongest connectivity effects were observed in a region of the lateral occipital cortex of both hemispheres which showed highest correspondence to visual area LO2 [Malikovic et al, ] implicated in visual scene processing [Larsson and Heeger, ]. In addition, significant coupling of the dmPFC was found with a cluster in the depth of the right pSTS (Fig.…”

“…In contrast, whole‐brain connectivity of the right pSTS during mentalizing was restricted to a region which most likely represents the visual area LO2 [Malikovic et al, ]. Region LO2 has been proposed to be crucially involved in perceptual organization based on spatial relations, such as grouping of shape information in a visual image [Larsson and Heeger, ].…”

Previous research suggests a role of the dorsomedial prefrontal cortex (dmPFC) in metacognitive representation of social information, while the right posterior superior temporal sulcus (pSTS) has been linked to social perception. This study targeted these functional roles in the context of spontaneous mentalizing. An animated shapes task was presented to 46 subjects during functional magnetic resonance imaging. Stimuli consisted of video clips depicting animated shapes whose movement patterns prompt spontaneous mentalizing or simple intention attribution. Based on their differential response during spontaneous mentalizing, both regions were characterized with respect to their task-dependent connectivity profiles and their associations with autistic traits. Functional network analyses revealed highly localized coupling of the right pSTS with visual areas in the lateral occipital cortex, while the dmPFC showed extensive coupling with instances of large-scale control networks and temporal areas including the right pSTS. Autistic traits were related to mentalizing-specific activation of the dmPFC and to the strength of connectivity between the dmPFC and posterior temporal regions. These results are in good agreement with the hypothesized roles of the dmPFC and right pSTS for metacognitive representation and perception-based processing of social information, respectively, and further inform their implication in social behavior linked to autism.
