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)’...

The insula of reil revisited: multiarchitectonic organization in macaque monkeys

Gallay, D. S. ; Gallay, M. N. ; Jeanmonod, Daniel ; Rouiller, Eric M. ; Morel, Anne

In: Cerebral Cortex, 2012, vol. 22, p. 175-190

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, with...
