Fig 3. Independent component analysis (ICA) on encoding time-series.

The depicted component is significantly associated with the occurrence of subliminal Face-Occupation Pairs. A: Clusters within the component encompassing bilateral hippocampus, amygdala, superior temporal sulcus, and temporal pole. These brain regions are important for episodic and semantic memory. Coordinates are according to MNI space; left is left on the coronal slice and upwards is left on the transversal slice. B: The temporal coupling of this network is specific for unconscious associative encoding. The component is significantly associated with the occurrence of Faces-Occupation Pairs (Pearson’s r = -.16, ** p = .004) but not with Faces Alone (Pearson’s r = .13, p = .69). The regression fit of the component is significantly better with Face-Occupation Pairs than with Faces Alone (* p = .044, effect size r = .35). The bar plot shows β-weights of the time course modelled specifically to the associative and the baseline condition. Error bars indicate the SEM.
