Reply to Synapses and Electricity (Peter Gow) --__--__-- Message: 1 From: "Peter Gow" To: eskrima@martialartsresource.net Date: Sat, 29 Jul 2006 23:59:26 +0000 Subject: [Eskrima] Reply to Synapses and Electricity Reply-To: eskrima@martialartsresource.net Mike, I apologise for taking so long to reply - flat out at work. Except from the Wikipedia : Under Synapse An electric synapse, unlike a chemical one, uses channels known as gap junctions to permit direct transmission of signals between neurons. Such synapses are found in the human body, within many organs. Last time I looked the brain is an organ Strongly suggest that you look up Coulomb's Law, the meaning of charge as applied to electron's held in the atomic structure. Also the amount of chemical electrical charge in the brain cell is determined by the amount of seretonic acid level in each cell. Technically speaking many chemical reactions involve electron transfer so it can be argued that there are only electrical synapsis. Something that you might find interesting is that scientists have grown dendrites on a single silken spider web thread. This has many implications as I am sure that you will understand. Galang, Peter Gow Australia Peter Gow wrote: "You cannot compare static electricity which you build up as you walk along the carpet with DC electricity or AC electricity for that matter they are all different. Although the electricity that passes from one sanapsis(?) connection to the next sanapsis connection in your brain is electricity." 1) Sorry, but electricity is electricity, however generated. It is about electrons travelling from A to B. What electricity can do is dependent on the mode of generation. 2) No electricity passes across the neuronal synapse. Neurotransmitters such a acetylcholine, dopamine, GABA and others pass across the synapse to induce or inhibit depolarization in the neuronal axon and thus passages of neural impulses which are dependent on movements of ions in and out of the nerve cell. That certainly involves electrical changes and would be loosely covered by the term "electricity". A great little book on the topic (although to some extent now dated) is "Nerve, muscle and synapse" by Sir Bernard Katz who got his Nobel prize for the work on this stuff. May be hard to find though...
