fMRI reflects functional connectivity of human somatosensory cortex

  author={Maria Blatow and Ernst Nennig and Anita Durst and Klaus Sartor and Christoph Stippich},
Unilateral sensory stimulation reliably elicits contralateral somatotopic activation of primary (SI) and secondary (SII) somatosensory cortex. There is an ongoing debate about the occurrence and nature of concomitant ipsilateral SI and SII activation. Here we used functional magnetic resonance imaging (fMRI) in healthy human subjects with unilateral tactile stimulation of fingers and lips, to compare somatosensory activation patterns from distal and proximal body parts. We hypothesized that… CONTINUE READING
