Parameters for the connectivity profiles used to construct the thalamocortical network. Connection profiles are listed per layer and neuron type for the large-scale model. Gaussian connections are selected according to a Gaussian distribution (σ = 7.5) with a peak of Pmax. Rectangular connections are selected by the maximum probability Pmax within a rectangular area. The radius of the Gaussian connections and size (area) of rectangular connections are measured in no. of neurons (so 10 × 10 means a probability distribution over a square of 10 neurons). Strength (expressed in no. of simultaneous PSPs per connection) is a modifier of the synaptic currents defined in materials and methods. The mean delay of the spike impulse from the source cell to the target cells and its SD are measured in ms.
Exc, excitatory; Inh, inhibitory; Infra, infragranular; Supra, supragranular.
