Abstract
Conclusions: There is little evidence to support the concept that spaceflight induces fundamental sympathetic neuroplasticity. The available data seem to support the hypothesis that regardless of whether or not sympathetic traffic is altered during flight, astronauts return with reduced blood volumes and consequent heightened baseline sympathetic activity. Because of this, the ability to withstand an orthostatic challenge postflight is directly proportional to an astronaut's maximal sympathetic activation capacity and remaining sympathetic reserve.
