A Tree-Like Model for Brain Growth and Structure

Table 1

Properties calculated from a tree-like model for branched “polyneurons” with low (𝑓=3) and high (𝑓=10⁴) functionalities. At a pregel stage, 𝛽=0.1 and at the gel point, 𝛽=1. For 𝑓=3, the accurate relation 𝛽=(𝑓−1)𝛼 is used, as in (1a) and other equations in [4].

			𝛽=0.1			𝛽=1
𝑓	𝑁	𝑘	⟨𝑥𝑛⟩	⟨𝑥𝑤⟩	𝑟	⟨𝑥𝑛⟩	⟨𝑥𝑤⟩	𝑟
3	10^4	25	1.111	1.167	1.05	4	40	10
10^4	10^11	34	1.053	1.111	1.05	2	36	18
