Pitfalls in the interpretation of multielectrode data: on the infeasibility of the neuronal current-source monopoles. Reply to Gratiy et al.
Résumé
ELECTRIC MONOPOLES ARE INDEED COMPATIBLE WITH MAXWELL EQUATIONS. To the editor: In their commentary, Gratiy et al. (2013) suggest that according to Maxwell theory of electromagnetism, monopoles are impossible in neurons. However, to reach this conclusion, the authors make an approximation, which we argue below may not be valid in biological media.
