    Somatosensory-evoked potentials are influenced differently by isometric muscle contraction of stimulated and non-stimulated hand in humans

  • Original language description

    Using spatio-temporal source dipole analysis of 111 electroencephalographic signals in 10 right-handed men, source activities were evaluated in the left primary somatosensory cortex (S1), left (S2(L)) and right (S2(R)) secondary somatosensory cortex, anterior cingulate cortex (ACC) and posterior cingulate cortex (PCC). Ipsilateral hand muscle contraction was associated with a decrease of source activity in S1 and with subsequent increases in S2(L) and the PCC. Contralateral hand muscle contraction was accompanied by a decrease of source activity in bilateral S2 cortices followed by decreases in the S1 and anterior cingulate cortex.

    Somatické vyvolané potenciály jsou různě ovlivněny isometrickou kontrakcí stimulované a nestimulované ruky

  • Czech description

    Byla použita zdrojová analýza 111 EEG signálu u 10 praváků a vyhodnoceny zdrojové aktivace v levé primární somatosenzorické oblasti (S1) levé a pravé sekundární somatosenzorické oblasti, a předním a zadním cingulu. Ipsilateální svalová kontrakce snížilaaktivitu v S1 a zvýšila aktivitu zdroje v levé S2 a v zadní cingulární kůře. Kontralaterální svalová kontrakce snížila aktivitu v obou S2 oblastech a předním cingulárním kortexu.
