To what extent is the bipolar rheoencephalographic signal contaminated by scalp blood flow? A clinical study to quantify its extra and non-extracranial components

Table 1 Analysis of the REG I magnitude

Inter-individual statistics of the changes in REG I measured as rms value of each REG I ensemble average (σ). Subscripts mean BI = before inflation; DI = during inflation; AI = after inflation. Last row (t_R-F) is the time delay between the R wave of the ECG and the time at which ensemble averaged REG I begins to fall.
