Recent evidence from novel phytotron and free-air ozone (O3) fumigation experiments in Europe and America on forest tree species is highlighted in relation to previous chamber studies. Differences in O3 sensitivity between pioneer and climax species are examined and viewed for trees growing at the harsh alpine timberline ecotone. As O3 apparently(More)
Attentional modulation of early, primary sensory components is still a topic of debate, as studies have produced conflicting results concerning the existence of a modulation within the primary somatosensory cortex and its direction. We previously showed that attention to tactile stimuli in a stream with visual stimuli leads to a reduction of primary(More)
Over human leg muscles, three motor responses (MR) can commonly be elicited, namely short-latency reflex (SLR), medium-latency reflex (MLR), and long-latency reflex (LLR). The MLR is less well understood than SLR and LLR. As the response to subsequent stimuli may be used to characterize central influences of an MR, we were interested, whether the MLR(More)
