Ephaptic coupling in white matter fibre bundles modulates axonal transmission delays
Fig 2
Spatial profiles of action potentials and their EPs.
Shown are A: the piecewise linear profile, B: the piecewise quadratic profile, and C: the profile of an action potential generated with the biophysical model. D-F: EPs corresponding to action potential profiles in A-C. G-I: Log-log plots of the EPs (absolute values) at z = 0. Black lines indicate decay with d−3. (The notch at d ≈ 0.3mm is due to a change of sign).
