34 -Like the microcircuit, the mesocircuit represents four layers of cortex, L2/3, L4, L5, and L6, each consisting of a population of excitatory neurons and a population of inhibitory neurons. External input can be provided by a thalamic population TC.
35 -
36 -The mesocircuit is a spatially structured network model covering 4x4 mm² of cortical surface area which is similar in size to multi-electrode arrays in use today.
37 -
38 -The neurons of each population are assigned random positions in two-dimensional layers and they are connected with distance-dependent connection probabilities and conduction delays.
39 -
40 -The densities of neurons and local synapses in the network are assumed to be realistic, amounting to ~~1.2 million neurons and ~~5.5 billion synapses.
41 -
42 -The model accounts for both spiking activity simulated with [[NEST>>https://www.nest-simulator.org]] and local-field potentials relying on [[LFPy>>https://LFPy.rtfd.io]].

49 -To date, only a [[preprint>>https://arxiv.org/abs/1805.10235]] with detailed model documentation and preliminary results is available on arXiv.org.
50 -
51 -The Drive of this Collab provides access to a [[recent version of the model implementation>>https://wiki.ebrains.eu/bin/view/Collabs/mesocircuit/Drive]].
52 -
53 -The development of the mesocircuit model belongs to task "SGA2 T4.2.1 - Spiking mesoscale cortical models with spatial organization" and constitutes the [[component C2418>>https://plus.humanbrainproject.eu/components/2418]].

55 -The main contributors are Johanna Senk, Espen Hagen, Sacha J. van Albada and Markus Diesmann.
