How do you create electrical impulses inside the body?

I suspect it is a biochemical process. I skimmed the attached reference, and here is what I was able to pull out: \n\nThere is a complicated process that takes place in the neurons. Chemical action separates positive sodium and potassium ions from anions across a membrane, creating an electric field. Neurotransmitters open ion gateways in the membrane when the field is built up to a certain level. This allows an electromagnetic wave to travel down the nerve. \n\nIt is MUCH more complicated than that, but that is a simplified cartoon version of the events I think.

,Good made me think.  The same, I guess in the end your just exchanging electrons.  However, the impulse in the brain will not fire until a certain discharge potential is met.  Also there are moderators in the synapse gap that can slow down the current exchange.  Serotonin is one.

Just the usual stuff.  Use an electrolyte (H2SO4/HNO3), a couple of electrodes, a reduction table of half cell potentials, and some electricity.

Please don't try to feed a voltage into the patients -- most of them won't like being electrocuted!\n\nYour best hope would be to try and monitor the capacitance between the lead and the patient.  This would allow a passive (no voltage into the patients) monitoring system.\n\nBut you'll have to find out the biomechanics of this on your own...

Mostly epithelial motifications for collecting sensory impulses which are synaptic..an action potential forms after depolarization caused by a threshold stimulus

You have probably experienced static electricity. It's the charge that you create when you scuff your feet on a rug. Then when you touch a doorknob, you get a small shock. That's static electricity. \n\n    The reason why it works is a little more complicated. To start, you have to know that every object is made up of billions of tiny particles, called protons and electrons. These particles are so small they can only be seen with special microscopes. \n\n    Despite their small size, protons and electrons carry an electrical charge. Protons carry a "positive" charge, while electrons carry a "negative" energy charge. \n\n    Usually, the two different charges balance each other out, and nothing happens. But when two objects with like charges (all positive or all negative) come together, the charges repel and the objects move away from each other. Objects with opposite charges attract each other because the different charges want to enter a state of balance with each other. \n\n    Objects can get a negative charge by picking up electrons from other objects. For example, when your shoes scuff against the rug, your shoes are actually picking up electrons from the rug. The electrons fly over your body, giving you a negative charge. \n\n    Your new electrons fly over your body because they are looking for a positive charge. If you touch a metal doorknob, the electrons on your body will leap into the metal, attracted by the protons there. The transfer of electrons is actually a small electrical current, and produces the tiny electric shock you feel. \n\n    Lightning is like static electricity, except on a much bigger scale. Both lightning and static electricity happen because of the attraction between the opposite charges.

For most muscles, contraction occurs as a result of conscious effort originating in the brain. The brain sends signals, in the form of action potentials, through the nervous system to the motor neuron that innervates the muscle fiber. However, some muscles (such as the heart) do not contract as a result of conscious effort. These are said to be autonomic. Also, it is not always necessary for the signals to originate from the brain. Some reflexes are fast, unconscious muscular reactions that occur due to unexpected physical stimuli. Other actions such as locomotion, breathing, chewing have a reflex aspect to them; the brain will start the contractions, but continuation of the movements can become reflexive. The action potentials for reflexes to unexpected stimuli originate in the spinal cord instead of the brain.\nThere are three general types of muscle contractions: skeletal muscle contractions, heart muscle contractions, and smooth muscle contractions.\nFor skeletal muscles, the force exerted by the muscle is controlled by varying the frequency at which action potentials are sent to muscle fibers. Action potentials do not arrive at muscles synchronously, and during a contraction some fraction of the fibers in the muscle will be firing at any given time. Typically when a human is exerting a muscle as hard as they are consciously able, roughly one-third of the fibers in that muscle will be firing at once, but various physiological and psychological factors (including Golgi tendon organs and Renshaw cells) can affect that.\nYou can read more here\nhttp://en.wikipedia.org/wiki/Muscle_contraction

It's like a pressure or shock wave. \nImagine the Hiroshima bomb of menstral cramps. Like that.

its pretty simple, depending on the shock level you want. use a industrial plastic glove. with a small metal plate on the thumb and middle finger(make sure u don't touch them together) and hook up a circuit with high voltage and low amps. if amps are too high you will hurt someone fatally. circuit kits are available at local stores. this can be very dangerous, be careful. use only small shock devices.

Ok, Franko got it started-The action potential is propagated along the sensory axons, through the ulnar or other nerve (depending on exactly what part of your hand touched the stove), through the dorsal root ganglia (which is where the cell bodies for the sensory axon live) to the spinal cord.  There, they will release neurotransmitters at synapses with secondary sensory dendrites and cell bodies (which will send a signal on up the spinal cord to the brain) In addition, they will release neurotransmitters at synapses with interneurons, which synapse with motor neurons.  There motorneurons send axons to a number of muscles, such as the bicep.  A signal is generated at the motorneuron, sent down the axon, which then terminates on motor end-plates, which stimulate the muscle to contract, and thus pull the hand away.

Electroporation is a new gene delivery method to increase gene transfer and expression in vivo. It is thought to be based on formation of membrane pores followed by DNA electrophoresis into the cells.

For an EMG, a needle electrode is inserted through the skin into the muscle. The electrical activity detected by this electrode is displayed on an oscilloscope, and may be heard through a speaker. After placement of the electrodes, you may be asked to contract the muscle (for example, by bending your arm). The presence, size, and shape of the wave form -- the action potential -- produced on the oscilloscope provide information about the ability of the muscle to respond when the nerves are stimulated. There is some undeniable discomfort at the time the needle electrodes are inserted. They feel like shots (intramuscular injection), although nothing is injected during an EMG. Afterwards, the muscle may feel a little sore for up to a few days. You can read more about it here\nhttp://www.stjohnsmercy.org/healthinfo/test/neuro/TP012.asp

The cell membrane in the axon and soma contain voltage-gated ion channels which allow the neuron to generate and propagate an electrical impulse known as an action potential.\n\nSubstantial early knowledge of neuron electrical activity came from experiments with squid giant axons. In 1937, John Zachary Young suggested that the giant squid axon might be used to better understand nerve cells [2]. Since they are much larger than human neurons, but similar in nature, it was easier to study them with less advanced technology at that time. By inserting electrodes into the giant squid axons, accurate measurements could be made of the membrane potential.\n\nElectrical activity can be produced in neurons by a number of stimuli. Pressure, stretch, chemical transmitters, and electrical current passing across the nerve membrane as a result of a potential difference in voltage all can initiate nerve activity [3].\n\nThe narrow cross-section of axons lessens the metabolic expense of carrying action potentials, however thicker axons convey the impulses more rapidly. In order to minimize metabolic expense yet maintain a rapid conduction velocity, many neurons have insulating sheaths of myelin around their axons. The sheaths are formed by glial cells: oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system. The sheath enables the action potentials to travel faster than in unmyelinated axons of the same diameter whilst simultaneously spending less energy to "recharge" the action potential after. The myelin sheath in peripheral nerves normally runs along the axon in sections about 1 mm long, punctuated by unsheathed nodes of Ranvier which contain a high density of voltage-gated ion channels. Multiple sclerosis is a neurological disorder which results from abnormal demyelination of peripheral nerves. Neurons with demyelinated axons do not conduct electrical signals properly.\n\nps. I think I deserve some points

It is very unlikey that you would survive the current associated with that sort of electroporation, as it would be quite substantial to effect you in the same way it effects the cells used to generate hybridomas. For example, people struck by lightning sometimes display some symptoms you might expect from a minor electroporation effect. In short, the current necessary to have the effect would likely hurt you in many ways, like stopping your heart, than the electroporation would.

magnetic fields, if moved in the right way, can create electric currents. Those currents could mess with the nucleus and take it from metastable to unstable. All depends on how the magnetic fields are set up and how you change them.

When you go to touch something metallic (or the kids, LOL), hold a key or some other metallic object in your hand, and touch the car door, fridge, whatever, with the key instead of your hand.  You'll still feel a shock, but it's only about half as bad, (I guess) because you're allowing the current to flow through a larger area of your hand, rather than the little "lightning bolt" attacking one little spot on your hand.  I discovered that by accident many years ago; probably as I went to unlock my car door.\n\nAlso, you can reduce the static electricity generation by using a humidifier in the dry months.

ELECTRICAL IMPULSES sent down by "nodes" thru conducting pathways towards the atria and ventricles.......these atria and vents r made of muscles which contract on recievin the electrical shocks........and thats when the blood moves forward\nwhen their is no impulse being sent forward........the chambers of the heart relax and get filled with blood.....\n\njust waiting for the next impulse to come by and the heart contracts again\n\nthis goes on n on till u die!
