- •
We present a dynamic causal model for fMRI data of cortical layers.
- •
The model includes blood draining from lower to upper cortical layers.
- •
In simulations, neural coupling can be distinguished from blood draining effects.
- •
On real data, models with blood draining excel over models without blood draining.
