Layer-specific external inputs

External inputs	L2/3	L4	L5	L6
Thalamic	0	93	0	47
Gray matter	534	353	389	79
Other white matter	1072	1665	1609	2790
Total	1606	2111	1997	2915

Notes: From top to bottom, the estimated numbers of external inputs per neuron are shown for excitatory neurons in layers 2/3, 4, 5, and 6 for the 3 distinguished input types: Thalamic, gray matter, and other white matter inputs. The total number of external inputs is rounded for simulations (compare Table 4).
