The main goal of the laboratory is to exploit human intracranial recordings to obtain, integrating high spatial and temporal resolution, a four-dimensional representation of the cortical activity capable to render the spatio-temporal dynamics underlying cognitive and perceptual processes.
A specific attention is paid to the sensori-motor integration, and to the characterization of the neural activations shared by both action execution and action observation. These mirror mechanisms can be functionally described thanks to the possibility not only to identify the cortical regions responsive during an ecological task, but also to highlight how each region behaves in time.
Finally, thanks to the unprecedented spatiotemporal resolution characterizing stereo-electroencephalography recordings, we aim at bridging the gap between non-invasive recordings and the human brain, by co-registering stereo-EEG signal with EEG and fMRI signals. In this way, the task-induced modulations observed on non-invasive signals could be associated to a precise spatio-temporal description of the cortical generators activity, and consequently to a clearer explanation of their functional role.
