Sequential changes in flow pattern, ECoG, and CBF. Relationships between the Doppler flow
pattern, ECoG, and CBF were obtained in our model.

Relationship between CBF and RI and between CBF and PI. The left scatterplot shows the
correlation between logarithmic CBF and RI. The right scatterplot shows the relationship
between logarithmic CBF and PI. PI was statistically correlated with logarithmic CBF.

Relationship between percent CBF and PI. PI was negatively correlated with percent CBF. The
percent CBF was always <20% whenever PI was >4.0.
