Area of Science:

Computational neuroscience
Neuroimaging analysis
Complex systems theory

Background:

Dynamical systems on complex networks are used to study neural dynamics.
Existing models often lack realistic spatial embedding and connectivity of neural networks.

Purpose of the Study:

To investigate how cortical geometry influences neural activity propagation.
To compare activity propagation in a spatially accurate network versus standard models.

Main Methods:

Utilized detailed neuroimaging data to construct a rat cortical surface network.
Simulated activity propagation using simple spreading and connectivity rules.
Compared results with standard network models having similar coarse statistics.

Main Results:

Cortical geometry profoundly influences the speed of activation propagation.
Spatially accurate network models show different propagation dynamics than abstract models.

Conclusions:

Omitting physiological network structure in theoretical models can oversimplify neural dynamics.
Accurate modeling of phenomena like epileptic seizures requires incorporating brain's spatial architecture.
