A late positive waveform of the human evoked potential, the P3 or P3oo (latency 300500 msec), has been shown by numerous researchers to accompany the delivery of taskrelevant information which requires a decision or response from the subject (Sutton et al. 1965, 1967; Ritter and Vaughan 1969; Squires el al. 1973; Picton et al. 1974). The amplitude of this waveform is enhanced when such stimuli ...

Yet, as a consequence of the coexistence of the German Renewable Energy Sour...

The transformation of phenylethyl chloride to 3,4-dihydroisoquinolines is shown to proceed via phenonium ion. The evidence comes from a study of dideuterated analogue 4, and the monomethylated and dimethylated compounds 2 and 3.
