As in the ideal gas law, the universal gas constant allows for calculation of amount of energy associated with a certain group of molecules (see https://en.wikipedia.org/wiki/Gas_constant). As the Nernst equation compares the "osmotic pressure" to "electrical pressure", the universal gas constant is needed to convert amount of an ion on the two sides of a ...

If there is literature that you are building off of or comparing your approach to, I would look in their papers to see what values they used and use the same. This is the standard approach, as it yields easily comparable experimental results. If you are just looking for some ballpark numbers for less formal research, these guys used 1 mΩ, these guys did the ...

The phrase "fire together, wire together" comes from an explanation of Hebbian Learning and refers to the adaptation of synapses as a response to the firing of already connected neurons. This is one of several Synaptic Plasticity mechanisms. Two others that exist are Long Term Potentiation (strengthening and creation) and Long Term Depression (weakening and ...

You're basically trying to replicate the work of the Blue Brain Project. To get a good summary of their work, check out their 2015 Cell paper, where they describe assembling a few columns of the rat barrel (whisker sensing) cortex. In this incredibly specialised, small cortex there are a ridiculous amount of neurons (207 electrical sub-types), with a wide ...

The number of types varies depending on exactly how you count, but there are likely thousands, if not tens of thousands. NeuroLex has 775 named neurons, and that is just a fraction of all the neurons that exist. They vary in their size, their shape, the number, length, thickness, and branching pattern of their axons (if any), the number, length, thickness, ...

I think you are confusing speed with rate. The speed of light is how long it take to for light to get from one point to another, not how often light "events" arrive at the eye. To give an analogy, imagine a highway. There are 500 cars on that highway. They are traveling at 70 mph. Those cars then exit the highway onto a residential rode. They are ...

Without Potassium (K), no chemicals move. The Central Nervous System is comprised of a variety of chemicals, electrical signals and neurotransmitters to send a variety of signals through the brain and a variety of receptors of the nervous system. If you want to send a signal of neurotransmitters (medications/ or other chemicals found in your list), there ...

First, many neurons don't have action potentials at all, and of those that do some don't encode information based on firing rate (rather they use the timing of spikes or some other code). So the question isn't relevant for all neuron types. Further, even for neurons that do encode information based on firing rate, the "average" is often not a very useful ...
