WebIn an earlier study, the authors reported that cortical information flow assessed by bivariate Granger causality decreased abruptly in all parts of the brain at propofol-induced loss of responsiveness. The authors subsequently noted that there is no accepted convention for the sign of the autoregressive coefficients.
