Short- and Long-Latency Median Somatosensory Evoked Potentials

Cortical Reorganization of Early Somatosensory Processing in Hemiparetic Stroke

“…Additionally, while not statistically significant, the reduced amplitudes are in line with prior studies on SEP's post-stroke [36][37][38]. The negative linear relationship between P50 amplitude and Fügl-Meyer impairment shows that the degree of the motor impairments is related to the hemispheric shift in cortical responses of sensory information post-stroke.…”

N̄20 and P̄40 somatosensory evoked potentials: Thalamic lesions and subcortical origin

“…Small latency delays between potentials and those recorded in the scalp are not convincing arguments against thalamic generation since such delayes can occur even across small distances in the cortex (23). Using non-cephalic references, widespread scalp potentials have been reported (8,23,24). It seems unlikely that these potentials were a feature in the findings reported in the apallic state (15) or in our data both because of differences in configuration and the use of cephalic references.…”

“…Similar disruption of scalp SSEPs were found in Case 3, stimulating in the arm and leg contralateral to the left middle cerebral artery infarc- variability has been used to argue for possibly independent thalamocortical projections mediating regionally specific SSEPs (8,19). Generation of scalp SSEPs in thalamocortical radiations is possible since travelling impulses can produce a fixed potential (20).…”

“…5c ). However, long latency biomarkers are more complex in its relation with median nerve stimuli due to its association with indirect somatosensory pathways involving cognitive and motor processes 77 . Hence, the P27-N20 complex was focused due to its prominent and well established association to contralateral stimuli at the S1 region 78,79 .…”
