fMRI Experiment 2: behavioral and multivariate fMRI results. (a) Across all three testing sessions, subjects rated odorant pairs belonging to the same (vs. different) perceptual category as significantly more similar. (b) Spatial ensemble patterns of fMRI activity (mean ± s.e.m.) in OFC showed significantly more overlap between categorically similar (vs. different) odorants at pre-deprivation. Following deprivation, these pattern differences significantly diminished, returning to baseline levels after recovery. (c) A scatterplot highlights the correlation between the magnitude of quality-related pattern decorrelation in the OFC and subject-wise perceptual changes in odor similarity ratings, from pre- to post-deprivation. Each diamond represents one subject. *, p < 0.05.
