Accordingly, the AUROC and AUPR values) were calculated by thresholding the absolute values of the connection coefficients using a set of threshold values ranging from 0 to ∞.
What if the connection of, for example, the low-threshold salt sensor toward reflex behavior would be tuned differently from its connection toward reinforcing neurons?
In order to eliminate negative correlations but avoid disconnection of some parcels, a proportional threshold retaining the top 40% of all connections was applied to each connectivity matrix (see Results for detailed information on this choice of threshold).
The new connection request threshold is 50 and the adaptive coding threshold is 35.
Instead of choosing a single coefficient threshold, we used a range of thresholds determined by connection densities (proportions of connections present in a graph to all possible connections) varying from 0.1 to 0.5 (increments of 0.05) to compare the properties of emerging networks.
All of the indications of high output were due to appropriate measurement of high threshold caused by chronic high thresholds, lead dislodgements, acute effects of lead maturation, or incomplete connection of the lead in the header block.
All of these indications of high thresholds were due to appropriate measurement of high thresholds (five patients), lead dislodgements (four patients), acute effects of lead maturation (six patients), or incomplete connection of the lead in the header block (one patient).
We used number of connections as a threshold for small versus large CWSs, where those with fewer than 200 connections are considered "small" [ 26].
A test statistic was then computed for each connection and a threshold applied (t = 3.1) to produce a set of suprathreshold connections, thereby identifying anatomical networks, which show significant differences in structural connectivity between groups.
Connectivity matrices were then binarized using a series of thresholds that preserved 10 100% of connections.
