We conduct a set of 20 simulations of 1 second duration, each using 500 random
current injections of amplitudes between 0-150 pA and lasting 0-5 ms. We compare
the spike-capturing accuracy of the full system to that of reduced systems of different
dimensions. In the reduced systems, the V-Slim tolerances are ⅛,_ca∣ = 0.002, ε{_ocal =
0.0005, εgi_obal — 10^⁶, and Sg_lobal = IO^-5, and the step between snapshots in the global
active zone is 4. The application of Branch-Ortho leads to highly accurate and fast
reduced systems, as Figure 3.7 and Table 3.6 show.

traces computed from the full and reduced systems (blue and red lines, respectively) in
response to a 500 pA step current stimulus lasting 9 ms applied at the soma. The reduced
system size for this plot is k_v — kf = 90. (b) Bar plot showing the percentage matched and
mismatched for the reduced systems for cell AR-1-20-04-A.

3.4.2 Results on Other Morphologies

The POD and DEIM modeling framework is applicable to a wide class of neurons.
We have assembled a broad test group of neurons from (http://NeuroMorpho.org)
(Ascoli, 2006). In Table 3.7 we summarize the accuracy and speed of the correspond-
