Thanks for the answers guys, any further answers will also be appreciated, but I think I'll have to start digging into some research papers, as Pythagorean has listed. Been very helpful so far :). edit: For others that are interested, there's some good papers on http://jn.physiology.org/

So am I to assume due to the relatively speculative nature of most of these answers, and most out there on the net. there's still a lot of research to be done?

I was referring to the English definition of the word: "a discrimination between things as different and distinct;", so "differ" would be fine too. I extended my question a bit, I meant in terms of each synapse, why do the neurotransmitters stored for release change between synapses, ie synapse...

Of late, I have been self-learning about the underlying biology behind neurons; saltatory conduction; electrotonic and action potentials. I have (at least for the most part) surmised a basic understanding of how most of this works. What I don't understand, is how do the neurons differentiate...

I am having trouble with calculating the error at the hidden layer in a back propagation network. I have calculated the error at the output layer successfully (and verified against a working network) with the following: for (int k=0;k<(layers[1]->n_neurons);k++) { //error = (desired -...

Thanks!

So I'm doing some programming, and to simplify a very large amount of if statements, I've decided to put it down to a few lines with a simple equation, I've done this before with other things, but it was very much trial and error. Therefore I'd like to see how it can be done in a more...

Thanks JesseM, this really helped in understanding it all, and the semi-complex nature of special relativity. Definitely printing that out for keeps in helping my understanding. regards

I need help with this as well; I'm trying to get my head around it and its so much... fun and frustration at the same time, fun because its so interesting, frustrating because I don't understand it as much as I wish too. Here is my similar problem: A spacecraft is moving at 80% the speed...

Any hardware store and most supermarkets will stock NaOH as 'Caustic Soda', 'Draino' etc. A quick Wikipedia search returns this: Noted as 99.8% is what is mentioned on the side on most Australian brands, unless you get it in solution. Just note NaOH will naturally decompose with Air to NaHCO3...

Sorry, I forgot these details. And yes electrolysis was not a great way to go. I knew there would be some drawbacks with the galvanization. Would the most 'appropriate' reaction be: 2NaCl(aq) + 3Fe(s) + 3H2O(l) > 2NaOH + H2(g) + 2Fe(OH)2(aq) + Cl2(g) + FeO(aq) [SIZE="1"]Note: I am very tired...

I for inquisitional purposes only recently attempted electrolysis of Iron to create Iron oxide. I used a car battery charger (12v, 2.7A) and two large (assumed iron) nails; a de-ionized water solution (200ml) with approx. 15g sea salt (claimed 99.995%). After starting the reaction (outside with...

Perhaps it might help if you described what chapter you've done, and surely as said above, you should just know to check your book for the equations that are relevant to your (current course progress)/test.
