Do neurons generate monopolar current sources?

Résumé

According to the "standard model," electric potentials such as the local field potential (LFP) or the electroencephalogram (EEG) are generated by current dipoles made by cerebral cortex neurons arranged in parallel. In this issue of Journal of Neurophysiology, Riera et al. (2012) present experimental evidence that this standard model may be insufficient to account for LFP and EEG signals in the rat brain. The authors have designed a set of technically impressive experiments that question the validity of the dipole model. We briefly summarize these findings and then speculate on possible physical mechanisms to explain these surprising results.
