Ephaptic coupling in white matter fibre bundles modulates axonal transmission delays
Fig 3
EP at the centre of a circular axon bundle due to concentric spike volleys.
A: Microscopic cross-section of a fibre bundle, with spike-carrying axons marked in blue. B: Macroscopic extension of (a), with the active area (i.e. where axons carry spikes) marked in blue. C: Waveform of a spike (top), and the resulting spatial (axial) profile of the EP at the centre of the fibre bundle. D: Cross-sections of C.
