The insula of Reil represents a large cortical territory buried in the depth of the lateral sulcus and subdivided into 3 major cytoarchitectonic domains: agranular, dysgranular, and granular. The present study aimed at reinvestigating the architectonic organization of the monkey's insula using multiple immunohistochemical stainings (parvalbumin, PV; nonphosphorylated neurofilament protein,...

Interhemispheric sensorimotor integration; an upper limb phenomenon?

Ruddy, Kathy L. ; Jaspers, Ellen ; Keller, Martin ; Wenderoth, Nicole

In: Neuroscience, 2016, vol. 333, p. 104–113

Somatosensory information from the limbs reaches the contralateral Primary Sensory Cortex (S1) with a delay of 23 ms for finger, and 40 ms for leg (somatosensory N20/N40). Upon arrival of this input in the cortex, motor evoked potentials (MEPs) elicited by Transcranial Magnetic Stimulation (TMS) are momentarily inhibited. This phenomenon is called ‘short latency afferent inhibition (SAI)’...
