Jung K, Eickhoff S, Caspers J, Popovych O
Netw Neurosci
. 2024 Dec;
8(4):1400-1420.
PMID: 39735513
The neurodegenerative progression of Parkinson's disease affects brain structure and function and, concomitantly, alters the topological properties of brain networks. The network alteration accompanied by motor impairment and the duration...

bioRxiv
. 2024 Jul;
PMID: 38948771
The balance of excitation and inhibition is a key functional property of cortical microcircuits which changes through the lifespan. Adolescence is considered a crucial period for the maturation of excitation-inhibition...

Zhang S, Jung K, Langner R, Florin E, Eickhoff S, Popovych O
Hum Brain Mapp
. 2024 Jun;
45(8):e26751.
PMID: 38864293
Effective connectivity (EC) refers to directional or causal influences between interacting neuronal populations or brain regions and can be estimated from functional magnetic resonance imaging (fMRI) data via dynamic causal...

Jung K, Florin E, Patil K, Caspers J, Rubbert C, Eickhoff S, et al.
Brain Commun
. 2023 Jan;
5(1):fcac331.
PMID: 36601625
Simulated whole-brain connectomes demonstrate enhanced inter-individual variability depending on the data processing and modelling approach. By considering the human brain connectome as an individualized attribute, we investigate how empirical and...

Neuroimage
. 2022 May;
257:119321.
PMID: 35580807
Dynamical whole-brain models were developed to link structural (SC) and functional connectivity (FC) together into one framework. Nowadays, they are used to investigate the dynamical regimes of the brain and...

Sci Rep
. 2022 Mar;
12(1):4331.
PMID: 35288595
Simulating the resting-state brain dynamics via mathematical whole-brain models requires an optimal selection of parameters, which determine the model's capability to replicate empirical data. Since the parameter optimization via a...

Domhof J, Jung K, Eickhoff S, Popovych O
Netw Neurosci
. 2021 Nov;
5(3):798-830.
PMID: 34746628
Recent developments of whole-brain models have demonstrated their potential when investigating resting-state brain activity. However, it has not been systematically investigated how alternating derivations of the empirical structural and functional...

Popovych O, Jung K, Manos T, Diaz-Pier S, Hoffstaedter F, Schreiber J, et al.
Neuroimage
. 2021 May;
236:118201.
PMID: 34033913
Modern approaches to investigate complex brain dynamics suggest to represent the brain as a functional network of brain regions defined by a brain atlas, while edges represent the structural or...

Neuroimage
. 2021 May;
237:118176.
PMID: 34000399
Dynamical modeling of the resting-state brain dynamics essentially relies on the empirical neuroimaging data utilized for the model derivation and validation. There is however still no standardized data processing for...
