    Abstract:
    Using Siemens type II rheograph 100 subjects aged 18 to 28 years were investigated analysing averaged rheoencephalographic curves from 50 repetitions by means of a Neuro-Averager apparatus made by Biomedica, and Anops 10 Biological Computer. The trigger for averaging was the QRS complex in ECG of the investigated subject. The records were obtained in sitting and lying positions. All curves were divided into the following types: U waves, U--W waves and W waves; positive and negative curves were also separated. The segment between the peak of the main wave and the beginning of the dicrotic wave was subjected to a particularly careful analysis. Because of its shape and accessory waves occurring there they were divided into alpha and beta waves. In the group of W waves L waves were separated. In sitting position 70% of the waves belonged to group W and positive waves were observed in 98% of this group. In lying position W waves accounted for 61% and positive waves for 12%. The shape of REG wave reflects the haemodynamic conditions in a given area and is changed, similarly as these conditions, with a change in the position of the subject.
