Connection strengths between neuron types.

Entries in the same columns correspond to the same presynaptic neuron type, entries in the same row to the same postsynaptic neuron type. Given are the total connection strengths (absolute values, sign in simulations in line with neuron type—excitatory/inhibitory), which are the product of the number of existing connections between two neuron types (or compartments) and the strength for individual connections. The total recurrence strengths and as well as the total mutual inhibition strengths and are varied in the simulations. Parentheses denote values that are only used when recurrence is introduced artificially.
