conclusions
Before describing the ways implemented to reach the diagnosis of our poor patient Mary Poppins of 'Hemimasticatory Spasm', we must anticipate that the encrypted code, considered a 'communication phenomenon', refers to a neurophysiopathological phenomenon called 'Hepatic Transmission', a very important and complex to evoke, but above all it requires the description of a topic that is sometimes taken for granted, that of 'electrical transmission between neurons'.
Electrical signaling is a key feature of the nervous system and gives it the ability to react quickly to changes in the environment. Although synaptic communication between nerve cells is primarily perceived as chemically mediated, electrical synaptic interactions also occur. Two different strategies are responsible for electrical communication between neurons. One is the consequence of low resistance intercellular pathways, called “gap junctions”, for the diffusion of electrical currents between the interior of two cells. The second occurs in the absence of cell-to-cell contacts and is a consequence of extracellular electric fields generated by the electrical activity of neurons.
In the chapter devoted to this fundamental topic (Two forms of electrical transmission between neurons), current notions of electrical transmission will be discussed from a historical perspective by comparing the contributions of the two different forms of electrical communication to brain function.
