Table 1 Calculation for estimated percent of OL-CalEx sheaths with outfoldings

From: Oligodendrocyte calcium signaling promotes actin-dependent myelin sheath extension

L (estimated average sheath length in OL-CalEx, 70% length of 150 μm sheath lengths previously reported)

OCL (outfolding connection length, from 3DSEM volumes)

CP (connection percentage: estimated % of sheath connected to outfolding = OCL / L • 100

MF, multiplication factor (100%/CP)
