[The role of the perivascular spaces in shaping the pulse waves of the intracerebral rheoencephalogram].
The intracerebral rheoencephalogram's pulse waves were recorded in rabbits and cats with indwelling electrodes. The waves' amplitude and form were rather diverse and they were inverted in 25% cases: the systolic peak was directed to an increase in the impedance. The dynamics of the waves reflect complex hemoliquorodynamic interrelations in perivascular space.
