Electrical field effect interactions in the vertebrate brain

People have many ways to love each other, some of which can sometimes be called unconventional … until the ways become familiar to everyone. The same applies for neurones. They possess several means to relate with each other, some of which are still unfamiliar to us and some others which are probably unknown. Since Sherrington's Integrative Action of the Nervous System , we have come to believe that nerve cells communicate primarily through specialized contacts or synapses, and this statement is undoubtedly true. However, we now appreciate that such is not always the case, and one class of neuronal interactions which does not involve specific junctions, that of field effects, is the subject of this review.
