2023, CognitionCitation Excerpt :Located between posterior MTG (lexical interface) and anterior MTG (combinatorial network), the L-MTG1 ROI together with the L-ITG1 ROI may play a transitional role between those functions in the ventral speech processing stream. Three regions in the ventral post central gyrus, L-postCG1, R-postCG2 and R-postCG3, aligned with portions of the sensory homunculus that are associated with the control of speech articulators (Pardo, Wood, Costello, Pardo, & Lee, 1997) and implicated in the perception of spoken language (LaCroix, Diaz, & Rogalsky, 2015; Schomers & Pulvermüller, 2016; Tremblay & Small, 2011a, 2011b). Two ROIs were identified within the LIFG, L-ParsTri1 and L-ParsOrb1, along with one right hemisphere homolog, the R-ParsTri1.
Beyond language: The unspoken sensory-motor representation of the tongue in non-primates, non-human and human primates
2022, Neuroscience and Biobehavioral ReviewsCitation Excerpt :Within ventral S1, an orderly somatotopic map was maintained following a dorsal to ventral axis representing the lips, teeth, and tongue, respectively (3 Hz, Sakai et al., 1995). Roughly similar findings were observed also in different positron emission tomography (PET) studies delivering either manual strokes (Pardo et al., 1997) or vibrotactile stimulations (Boling et al., 2002) to both sides of the tongue. In addition to cortical responses contralateral to the stimulation (ventral portion of areas 3/4, at approximately 28 mm above the intercommissural plane, Pardo et al., 1997), ipsilateral foci at the central sulcus were also evident only in the left but not in the right hemisphere.

2015, Physiology and BehaviorCitation Excerpt :Recent papers have discussed the pattern of somatosensory and taste projections from each side of the tongue to the ipsilateral or contralateral cerebral hemispheres in humans. There is a consensus that both sides of the tongue in both the somatosensory and the gustatory modalities are represented in the cortex of both hemispheres [1,2,10,22,38–40,59], most likely with a predominance of contralateral over ipsilateral representations in the somatosensory modality and an opposite predominance of ipsilateral over contralateral representation in the taste modality [3,10,22]. There are also reports of a comparatively greater reactivity of the right hemisphere to both somatosensory [50] and gustatory lingual stimuli [52].
