Extended Data Fig. 6: Subject-wise temporal RSA after accounting for intensity and pleasantness.

a. The temporal profile of the perceptual similarity regression coefficients (standardized beta values) (orange) overlaid on the sniff flow temporal profile (blue) averaged across subjects when perceptual similarity was based on all descriptors except intensity. Solid lines indicate the time-points when the regression coefficient was significant (P < 0.05, subject-wise one-tailed t-test, panel b for at least 2/3 subjects) and dashed lines denote otherwise. b. Temporal perceptual representational similarity (without intensity) in individual subjects. Solid lines indicate the time-points where the regression coefficient was significant (P < 0.05, FDR corrected across time-bins, one-tailed t-test, N = all unique pairs of 4560 (S1), 4320 (S2, S3) trials: 10394520 (S1) and 9329040 (S2, S3))), and dashed lines denote otherwise. c. Perceptual representational similarity (without intensity) in a. plotted as a function of sniff flow rate. d. Perceptual similarity (without intensity) plotted as a function of sniff flow for individual subjects. e. The temporal profile of the perceptual similarity regression coefficients (standardized beta values, orange) overlaid on the sniff flow temporal profile (blue) averaged across subjects when perceptual similarity was based on all descriptors except pleasantness. Solid lines indicate the time-points when the regression coefficient was significant (P < 0.05, subject-wise one-tailed t-test, panel f for at least 2/3 subjects)) and dashed lines denote otherwise. f. Temporal perceptual representational similarity (without pleasantness) for individual subjects. Solid lines indicate the time-points when the regression coefficient was significant (P < 0.05, FDR corrected across time-bins, one-tailed t-test, N = all unique pairs of 4560 (S1), 4320 (S2, S3) trials: 10394520 (S1) and 9329040 (S2, S3))) and dashed lines denote otherwise. g. Perceptual representational similarity (without pleasantness) in e. plotted as a function of sniff flow rate. h. Perceptual similarity (without pleasantness) plotted as a function of sniff flow for individual subjects. All subject-wise results were corrected for multiple comparisons across time-bins by an FDR correction (Benjamini-Hochberg procedure).
