(explains all the bad writing, too)<br />What I recall is a current of 60 to 100 mV. One AP (action-potential) takes around 50ms (or was it 50Hz? damn, really have to look up all the stuff again)<br />But you don't want only one. Depending on (again) the kind of neuron it will follow a different pattern. Most of them will simply stop reacting after a certain time. Plus you have to wait until the neuron can regenerate the ability to send a signal. <br />Guess it makes more sense to look it up tomorrow and back up my claims with some more information ;) don't want you to have to trust in my word<br />But yeah, should be not too difficult actually.

I'm not quite sure who o...About the electrodes:<br />I'm not quite sure who of you ever worked with measuring and inducing of neural signals, so if there is someone more experienced than I am please ignore.<br />I hat one course in Neurobiology plus several in biochemistry and so on, so I am well aware of the working principle of neurons. What we used when recording the signals of neurons were simple platinum wires. The whole electrode was a small wire. Most of it was coated so it wouldn't pick up currents from an area but only the one that was touching the very top of the wire. Think of a wire completely coated but then you cut one end, it still is coated but at the end there is one spot of blank metal. <br />We had to hook it up directly to a neuron, of course.<br />As in this case the electrode should induce a signal rather than record one this kind of accuracy is not necessary. I would think of a small ring (diameter of maybe 2mm? need to look up the neuron-density in the target tissue) which is not coated. You can get platinum wires as lab supply, for what I know. Never tried though. <br />One problem I can think of is not to induce the signal to too many neurons, or too strong of a signal (shocks...) and not to hit the wrong ones. If hitting the motor-neurons they will trigger musclemovement. <br />Also it would be interesting if the electrodes have to be set up all around the ankle like the motors of the northpaw are or if they just have to trigger different areas. My guess would be: different areas should suffice, but an experiment with an actual northpaw could clarify that quite easily...<br />Hope I could help a little...<br />BenBenhttp://vokabeln@online.denoreply@blogger.comtag:blogger.com,1999:blog-4667295582801858613.post-611413812533701752011-01-11T16:48:04.205+00:002011-01-11T16:48:04.205+00:00I really need to learn more about op-amps; I only ...I really need to learn more about op-amps; I only know enough to know I haven't scratched the surface.Unqualified to speaknoreply@blogger.comtag:blogger.com,1999:blog-4667295582801858613.post-62389594509566327952011-01-11T16:33:45.587+00:002011-01-11T16:33:45.587+00:00you can use a 555 and an LC series to get an a som...you can use a 555 and an LC series to get an a somewhat ok sine (with a a few jumps), simmilar is used for cheap 128kHz rfid equipment. would be good enough for charging already... even if the guys from the EMC lab will curse you. using op-amps you can get a lot cleaner sine-waves.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-4667295582801858613.post-66302447576410468472011-01-11T15:49:12.766+00:002011-01-11T15:49:12.766+00:00@Anon: I was thinking of induction coils at the ti...@Anon: I was thinking of induction coils at the time.

It would be a bit of cheating, but in the same time reduce the number of components to develop.<br /><br />I guess the biggest hassle will be making sure the holes where the electrodes leave the bioproof compartement stay tight, because I can't help but think of them as cracks (which they are, but shouldn't!)
