While the above described reports provide possible perceptual correlates for bilateral interactions that might occur in SII, such as those identified in the present study, it will remain uncertain until anterior or posterior SII cortical activity is studied under conditions that permit direct correlations of perceptual performance and cortical activity under precisely controlled conditions of contralateral vs. bilateral skin stimulation. | |||||||||||||||

|
Simoes et al. [9] showed significant suppression of the MEG SII response in humans, with simultaneous inputs delivered to the same skin sites, and Hoechstetter et al. [10] described "interactions" in SII cortex (a response that was not the summation of the ipsilateral and contralateral response) to simultaneous bilateral stimuli. | |||||||||||||||

|
While some investigators have proposed that monkey SII occupies a higher position in the somatosensory information processing hierarchy than does SII in cat [20], others have warned that "these are basically descriptive schemes of connections that do not illuminate what features of somesthesis are selectively projected" and that "they also tend to ignore potential interdependence between SI and SII" [26]. | |||||||||||||||

Converging evidence from many literatures implicates insula as the most reliable region in brain imaging studies on pain [34], and considers it as a limbic integration cortex for complex and preprocessed sensory information with direct association with the SI, SII, prefrontal areas and amygdala, which are important sources of hippocampus and ACC afferents [35-38]. | |||||||||||||||
| |||||||||||||||
|
These regions process information in circuits that can broadly be assumed to engage: the affective (amygdala, hippocampus), sensory (thalamus, primary (SI) and secondary (SII) somatosensory cortices), cognitive (ACC, anterior insula), and inhibitory (PAG, hypothalamus) processing during the experience of pain [8]. | |||||||||||||||

|
Group comparisons revealed that overall, SII responding of adults with ADHD showed markedly less source power than that of controls (Figure 5C). | |||||||||||||||
| |||||||||||||||
|
Accordingly, our aim was to characterize ERD and ERS in the alpha and beta bands in SI and SII in response to randomly and predictably presented electrical stimulation of the median nerve in adults with and without ADHD. | |||||||||||||||

The Somatosensory Cortex in this study was defined as the combination of the primary somatosensory cortex (SI), which includes the central sulcus in its lower bordering posterior wall (putative BA 3b) with postcentral gyrus (putative BA 1), as well as the secondary somatosensory cortex (SII) localized in the subcentral section lateroventral to the postcentral gyrus on the operculum Rolandi (putative BA 43) [14]. | |||||||||||||||

Following a wash to remove any unbound substances and/or antibody enzyme reagent, substrate solution was added to the wells allowing the colorometic reaction in proportion to the amount of sTF, sTM and D-D bound. | |||||||||||||||
