In this combined electroencephalographic and magnetic resonance imaging (MRI) study, the asymmetry of functional and structural measures in the human parietal operculum (PO) were investigated. Median nerve somatosensory evoked potential recordings showed maximum scalp potentials over contralateral (N80, N110) and ipsilateral (N100, N130) temporal electrode positions. In accordance, MRI-coregistered source analysis revealed two electrical sources in the contralateral (N80, N110) and two in the…

Differences between anatomical and functional connectivity as well as between species, however, highlight the need for an integrative view on connectivity, including comparison and cross-validation of results from different approaches.

In situations involving unilateral tactile object recognition, contra- and ipsilateral SII will induce an asymmetrical functional connectivity to other brain areas, which may occur by the hand contralateral effect of SII.
Vestibular inputs modulate somatosensory cortical processing
- Biology, PsychologyBrain Structure and Function
- 2012
Somatosensory potentials evoked by left median nerve stimulation are recorded, before and immediately after left cold caloric vestibular stimulation (CVS), in a small-scale study of eight healthy volunteers, believing this results provide the first clue linking brain structure to function for the interaction between Vestibular and somatoensory systems.

The data suggest that early interhemispheric somatosensory integration primarily occurs in SII, is mediated by callosal fibers that interconnect homologous SII areas, and has behavioral importance for bimanual object manipulation and exploration.

When a large sample of normal individuals is considered, cerebral asymmetries are only subtly associated with callosal thickness, and leftward asymmetry and increased magnitude of asymmetry were generally associated with increased callosal Thickness.

Evidence for interhemispheric processing of inputs from the hands in human S2 and PV.
- Biology, PsychologyJournal of neurophysiology
- 2001
The fMRI results indicate that, as in monkeys, S2/PV receives inputs from both the contralateral and ipsilateral hand and the MEG data suggest that information is processed serially from S1 to S2, which indicates that extensive intrahemispheric processing occurs before information is transferred to the opposite hemisphere.

All subjects showed additional deflections which peaked after 85 ms; the source locations agreed with the sites of the secondary somatosensory cortices (SII) in both hemispheres; the SII responses were typically stronger in the left than the right hemisphere.
