With the anatomy and connectivity of an individual characterized, a key question is how and at what scale should function, as it is relevant and practical to emulate the individual, of the brain be modeled? Certainly, neuronal function can be described and modeled at many scales, from molecular mechanisms to large-scale hemodynamic fluctuations. In determining the scale, we are guided by modern neuroscience findings, and particularly relevant are findings on the organization of the cortex. The cortex is a layered “sheet” of interconnected neurons and can be parcellated into areas based on function and neuronal architecture. At a fundamental unit, the cortex can be thought of as being composed of multiple mini-columns (~40 µm), the so-called hyper-columns (~200-800 µm). Across the layers of a mini-column, the organization of neuronal connectivity is canonical and has been described as a microcircuit that is dynamically configurable based on inputs to the circuit (de Costa & Martin, 2010). The activity of the canonical microcircuit (CMC) can be detected with local field potentials (LFP) recordings proximal to the neurons, and the spatial decay of the LFP suggests that its resolution is approximately over several hyper-columns (3-5 mm). LFPs are seen at the scalp as the electroencephalogram (EEG). Because the EEG is recorded at the scalp, inferring the source of the EEG requires advanced modeling and analytic tools. However, if done correctly, dense-array EEG can be used to analyze brain activity at a spatially resolved scale of less than one centimeter.
