abstract = {Simulated whole-brain connectomes demonstrate an enhanced
inter-individual variability depending on data processing
and modeling approach. By considering the human brain
connectome as an individualized attribute, we investigate
how empirical and simulated whole-brain connectome-derived
features can be utilized to classify patients with
Parkinson’s disease against healthy controls in light of
varying data processing and model validation. To this end,
we applied simulated blood oxygenation level-dependent
signals derived by a whole-brain dynamical model simulating
electrical signals of neuronal populations to reveal
differences between patients and controls. In addition to
the widely used model validation via fitting the dynamical
model to empirical neuroimaging data, we invented a model
validation against behavioral data, such as subject classes,
which we refer to as behavioral model fitting and show that
it can be beneficial for Parkinsonian patient
classification. Furthermore, the results of machine-learning
reported in this study also demonstrated that performance of
the patient classification can be improved when the
empirical data are complemented by the simulation results.
We also showed that temporal filtering of blood oxygenation
level-dependent signals influences the prediction results,
where the filtering in the low-frequency band is advisable
for Parkinsonian patient classification. In addition,
composing the feature space of empirical and simulated data
from multiple brain parcellation schemes provided
complementary features that improve prediction performance.
Based on our findings, we suggest including the simulation
results with empirical data is effective for
inter-individual research and its clinical application.},
