“…Importantly, the first whole-brain pattern shows fronto-temporal areas that have repeatedly been found in studies of co-speech gesture perception, such as left inferior frontal gyrus and left superior temporal gyrus (Dick et al, 2012;Green et al, 2009;Holle et al, 2008Holle et al, , 2010Willems et al, 2007Willems et al, , 2009). In addition, these areas are associated with semantic processes, such as word retrieval (left inferior frontal gyrus: Amunts et al, 2004;de Zubicaray & McMahon, 2009;Thompson-Schill et al, 1999;Tremblay & Gracco, 2006; superior temporal gyrus: Graves et al, 2010;Heath et al, 2012;Khader et al, 2010). This significant overlap of speech and co-speech gesture production is in line with the theoretical frameworks of co-speech gestures that posit that speech determines or initiates co-speech gestures, i.e., that co-speech gesture production is mainly driven by the language network (Hostetter & Alibali, 2008;Kita & Özyürek, 2003;McNeill, 1992McNeill, , 2005.…”

The perception of co-speech gestures, i.e., hand movements that co-occur with speech, has been investigated by several studies. The results show that the perception of co-speech gestures engages a core set of frontal, temporal, and parietal areas.However, no study has yet investigated the neural processes underlying the production of co-speech gestures. Specifically, it remains an open question whether Broca's area is central to the coordination of speech and gestures as has been suggested previously. The objective of this study was to use fMRI to (i) investigate the regional activations underlying overt production of speech, gestures, and cospeech gestures, and (ii) examine functional connectivity with Broca's area. We hypothesized that co-speech gesture production would activate frontal, temporal, and parietal regions that are similar to areas previously found during co-speech gesture perception and that both speech and gesture as well as co-speech gesture production would engage a neural network connected to Broca's area. Whole-brain analysis confirmed our hypothesis and showed that co-speech gesturing did engage brain areas that form part of networks known to subserve language and gesture. Functional connectivity analysis further revealed a functional network connected to Broca's area that is common to speech, gesture, and co-speech gesture production. This network consists of brain areas that play essential roles in motor control, suggesting that the coordination of speech and gesture is mediated by a shared motor control network.Our findings thus lend support to the idea that speech can influence co-speech gesture production on a motoric level.

Semantic Network Disconnection in Formal Thought Disorder

et al. 2012

Background: Structural and functional findings in schizophrenic patients with formal thought disorder (FTD) show abnormalities within left-side semantic areas. The present study investigate the network function of the involved brain regions as a function of FTD severity. Methods: We examined a group of 16 schizophrenia patients differing in FTD, but not in overall symptom severity, and 18 matched healthy controls. A passive word reading paradigm was applied during functional MRI (fMRI). A concatenated independent component analysis approach separated the fMRI signal into independent components, and spatial similarity was used to estimate the individual differences in spatial configuration of networks. Results: The semantic network was identified for both groups encompassing structures of the left inferior frontal gyrus, the left angular gyrus and the left middle temporal gyrus. The differences between the semantic networks of patients and controls increased with increasing severity of FTD. This difference was due to a decreasing contribution of the left inferior frontal gyrus (Brodmann area 45 and 47). Conclusion: Severity of FTD was correlated with a disruption of the left semantic network in schizophrenic patients. We suggest that FTD is a consequence of a frontal-parietal/temporal disconnection due to a complex interaction between structural and functional abnormalities within the left semantic network.

How familiarization and repetition modulate the picture naming network

et al. 2014

A common strategy to reveal the components of the speech production network is to use psycholinguistic manipulations previously tested in behavioral protocols. This often disregards how implementation aspects that are nonessential for interpreting behavior may affect the neural response. We compared the electrophysiological (EEG) signature of two popular picture naming protocols involving either unfamiliar pictures without repetitions or repeated familiar pictures. We observed significant semantic interference effects in behavior but not in the EEG, contrary to some previous findings. Remarkably, the two protocols elicited clearly distinct EEG responses. These were not due to naming latency differences nor did they reflect a homogeneous modulation of amplitude over the trial time-window. The effect of protocol is attributed to the familiarization induced by the first encounter with the materials. Picture naming processes can be substantially modulated by specific protocol requirements controlled by familiarity and, to a much lesser degree, the repetition of materials.
