Findings suggest a pMTG-IFG-pMTG neurocircuit loop in gesture-speech integration, which deepens current knowledge and inspires future investigation of the temporal dynamics and cognitive processes of the amodal semantic network. Keywords: gesture, inferior frontal gyrus, posterior middle temporal gyrus, semantic integration, speech, TMS.

Neuroimaging and patient research has emphasized the importance of left inferior frontal gyrus (IFG)—however, impaired semantic control can also follow left temporoparietal lesions, suggesting that this function may be underpinned by a large-scale cortical network.

TMS of IFG and pMTG was found to specifically disrupt gesture-speech integration, but not general task processing. By directly linking brain activity to behavior, our study demonstrates, for the first time, that both IFG and pMTG are causally involved in integrating information from the two domains of gesture and speech.

Jul 18, 2023 · Results showed that 1 Hz offline TMS over the right DLPFC and the right IFG at 110% intensity of the resting motor threshold had no effect on performance in the SSG. In fact, evidence in favor...

Apr 1, 2012 · Brain stimulation studies involving both TMS and tDCS have been carried out and suggest that areas including pre-SMA, IFG and FEF may be involved in successful inhibitory control, although it remains to be determined how restricted to inhibitory control that several of these regions are limited too.

Processing of infant signals in the adulthood brain is likely to recruit emotional empathy neural circuits, including the inferior frontal gyrus (IFG). Here, we used transcranial magnetic stimulation (TMS) to test the role of right IFG (rIFG) in behavioral responses to infant signals.

The posterior middle temporal gyrus (MTG) and inferior frontal gyrus (IFG) are two critical nodes of the brain's language network. Previous neuroimaging evidence has supported a dissociation in language comprehension in which parts of the MTG are involved in the retrieval of lexical syntactic inform …

We applied repetitive transcranial magnetic stimulation (rTMS) over anterior and posterior IFG (aIFG/pIFG), and vertex as a control site, while participants performed a category member and a rhyme generation task. We found a functional‐anatomical double dissociation between tasks …

Dec 16, 2015 · In that study, we found that increased functional connectivity between the right IFG and the right extrastriate cortex before TMS, and increased activity in the non-disrupted IFG after TMS, predicted resistance to the behavioral VWM impairment caused by TMS.
