Can we non-invasively resolve signals from different cortical layers in humans?
Recent computational, anatomical and physiological evidence suggests that feedforward signals tend to originate in supra-granular cortex and be of predominantly high-temporal frequency content (>30 Hz) whereas feedback signals tend to originate in infra-granular cortex and are characterized by slower dynamics (<30Hz). I will demonstrate that using new recording technology, it is now possible to make frequency-specific laminar inferences with magnetoencephalography (MEG) in a spatially localized and time-resolved manner, non-invasively and in vivo. I will describe global and local analyses for making laminar-specific inferences with MEG using parametric and non-parametric measures, and demonstrate their concordance in simulation. I will then present empirical evidence from a predictive action selection task which shows that spatially resolved laminar inferences of human sensorimotor and visual induced activity can be made using MEG, attributing low frequency (<30Hz) activity to infra-granular sources, and high frequency activity (>60Hz) to supra-granular sources. Finally I will discuss potential extensions of this technique to estimate the time course of laminar activity during evoked responses.
