      abstract     = {Multi-electrode arrays covering several square millimeters
                      of neural tissue provide simultaneous access to population
                      signals such as extracellular potentials and spiking
                      activity of one hundred or more individual neurons. The
                      interpretation of the recorded data calls for multiscale
                      computational models with corresponding spatial dimensions
                      and signal predictions. Multi-layer spiking neuron network
                      models of local cortical circuits covering about 1 mm² have
                      been developed, integrating experimentally obtained
                      neuron-type-specific connectivity data and reproducing
                      features of observed in-vivo spiking statistics. Local field
                      potentials can be computed from the simulated spiking
                      activity. We here extend a local network and local field
                      potential model to an area of 4x4 mm²⁠, preserving the
                      neuron density and introducing distance-dependent connection
                      probabilities and conduction delays. We find that the
                      upscaling procedure preserves the overall spiking statistics
                      of the original model and reproduces asynchronous irregular
                      spiking across populations and weak pairwise spike–train
                      correlations in agreement with experimental recordings from
                      sensory cortex. Also compatible with experimental
                      observations, the correlation of local field potential
                      signals is strong and decays over a distance of several
                      hundred micrometers. Enhanced spatial coherence in the
                      low-gamma band around 50 Hz may explain the recent report of
                      an apparent band-pass filter effect in the spatial reach of
                      the local field potential.},
