abstract = {Background: Despite the marked inter-individual variability
in the clinical presentation of schizophrenia, it remains
unclear the extent to which individual dimensions of
psychopathology may be reflected in variability across the
collective set of functional brain connections. Here, we
address this question using network-based predictive
modeling of individual psychopathology along four
data-driven symptom dimensions. Follow-up analyses assess
the molecular underpinnings of predictive networks by
relating them to neurotransmitter-receptor distribution
patterns. Methods: We investigated resting-state fMRI data
from 147 schizophrenia patients recruited at seven sites.
Individual expression along negative, positive, affective,
and cognitive symptom dimensions was predicted using
relevance vector machine based on functional connectivity
within 17 meta-analytic task-networks following a repeated
10-fold cross-validation and leave-one-site-out analyses.
Results were validated in an independent sample. Networks
robustly predicting individual symptom dimensions were
spatially correlated with density maps of nine
receptors/transporters from prior molecular imaging in
healthy populations. Results: Ten-fold and
leave-one-site-out analyses revealed five predictive
network-symptom associations. Connectivity within
theory-of-mind, cognitive reappraisal, and mirror neuron
networks predicted negative, positive, and affective symptom
dimensions, respectively. Cognitive dimension was predicted
by theory-of-mind and socio-affective-default networks.
Importantly, these predictions generalized to the
independent sample. Intriguingly, these two networks were
positively associated with D1 dopamine receptor and
serotonin reuptake transporter densities as well as
dopamine-synthesis-capacity. Conclusions: We revealed a
robust association between intrinsic functional connectivity
within networks for socio-affective processes and the
cognitive dimension of psychopathology. By investigating the
molecular architecture, the present work links dopaminergic
and serotonergic systems with the functional topography of
brain networks underlying cognitive symptoms in
schizophrenia.},
