Figure 3

Visualization of the linear network K-function. This figure clarifies what is meant by the quantities d ij , L T , T , L p i (t), and p i (t) which were used to compute the linear network K-function. Here d ij is the linear network distance shown by the gray line between points p i and p j . L T (in black) is the entirety of the single dendritic network and T is the length of L T . Similarly, L p i (t) (in blue dashed lines) is subset of the network where the distance between a point p i and any other point is ≤ t and p i (t) is the length of L p i (t). In this particular example there are 2 spines which fall within L p i (t) and would be counted in determining the empirical function value K ̂ (t), however point p j falls outside this radius and would therefore not be counted.
