was conducted with PDLI and PLI values as dependent variables comparing drug condition (ethanol, placebo) for the defined time frequency ROI’s. The third hypothesized question focused on whether differences in response to ethanol as indexed by PLI and PDLI values in the ROIs of interest were significantly associated with either blood ethanol concentrations or level of intoxication in the human participants. In these exploratory analyses linear regression was used to determine if a significant part of the variance in the PDLI/PLI measures following ethanol could be accounted for by: (1) the total score on the Subjective High Assessment Scale (SHAS) or (2) the blood ethanol concentrations (BEC’s).
