Layer-fMRI is a technique that uses functional magnetic resonance imaging (fMRI) to measure activity in specific layers of the cortex. This is done by acquiring high-resolution data and dividing cortical voxels into thin groups of different cortical depth. Layer-fMRI can be used to study the directional information flow between brain areas and see how different parts of the cortex work together to perform different tasks. However, layer-fMRI is still a relatively new method and there are some technical challenges for data acquisition and analysis. In this presentation, I will give an overview of common layer-fMRI acquisition and analysis approaches.
