There are many approaches to studying the inner workings of the brain and its highly interconnected circuits. One can look at the global activity in different brain structures using non-invasive technologies like positron emission tomography (PET) or functional magnetic resonance imaging (fMRI), which measure physiological changes, e.g. in the glucose uptake or blood flow. These can be very effectively used to localize active patches of brain tissue with up to millimeter-scale resolution but provide limited insight into the processes underlying this activity. At the heart of brain processes lies synchronized activity of neurons, neuronal assemblies and the wide-spread connections of neuronal networks, which give rise to the electrical activity recorded in the scalp electroencephalogram (EEG), cortical field oscillations in the electrocorticogram (ECoG), and the local field potential (LFP) and action potentials. This large scale of brain electrophysiology across a wide range of spatial and temporal scales presents significant technical challenges for the methods used to probe the activity of neural networks.
