From: Neurocognitive correlates of semantic memory navigation in Parkinson’s disease
PD patients presented hypoconnectivity in the (a) sensorimotor, (b) semantic, and (c) salience networks, whereas bvFTD patients exhibited selective hypoconnectivity in (d) salience network (networks’ colors indicate the effect size of the difference from HCs, expressed as Cohen’s d, ranging from 0 [black] to 6 [white]). In the PD-HC tandem, concreteness negatively correlated with connectivity of the sensorimotor and salience networks, imageability negatively correlated with sensorimotor network connectivity, and semantic variability positively correlated with salience network connectivity. In the bvFTD-HC tandem, semantic variability positively correlated with salience network connectivity. Non-significant correlations are shown with a gray mask. bvFTD: behavioral variant frontotemporal dementia; HCs: healthy controls; PD: Parkinson’s disease; SV: semantic variability; wSDM: weighted Symbolic Dependence Metric.
