(a) Mean scores across participants for the signal diversity measures LZsN, LZcN and ACEN are higher for each of the three drug conditions (white discs) than for the corresponding placebo conditions (black discs). A solid line across conditions indicates p < 0.001 and a dotted line 0.001 < p < 0.05, uncorrected, obtained from a two-sided t-test. (b) Difference in single channel Lempel-Ziv complexity, LZsN, between respectively PSIL, KET, LSD and placebo at the single participant level. The error bars indicate standard error across trials.
