Does the temporal summation of EPSPs accumulate linearly to action potential threshold or logarithmically to a plateau/limit?

I am attempting to determine which current inputs (in uA) are subthreshold for inducing a burst of activity. This is because I am attempting to model DBS form epilepsy in vitro, which clinically...

What should the phase and pulse duration be for deep-brain stimulation (DBS) for epilepsy?

In DBS settings, I have seen stimulus widths of up to 500 us in duration; however, the most common pulse duration seems to be between 90-150 us. Clinically, mono- or bi-polar electrodes can be...

1. If I can quantize the atom using this hyperbolic spiral and classical physics, could nature do the same?

If we map as a continuous motion an ionising electron (beginning its journey at n=1) in an H atom, a specific hyperbolic spiral appears (see animation). When we solve this spiral formula, we find...
