The carriers of the charge are ions and they get repelled from each other well enough. Other than their charge there is only the size in which they differ (for all practical purposes). This means, as long as we are talking about membrane potential, the actors are just a mix of 1+ ions which don't come near each other. When size matters, for example in an ion ...

You are looking for a review on vesicle cargoing along the cytoskeleton. This open access article is the most recent I found on the subject. From the abstract: How synaptic cargos achieve specificity, directionality and timing of transport is a developing area of investigation. Recent studies demonstrate that the docking of motors to their cargos is a ...

No, silicon oil couldn't block an ion channel. Oil is a nonpolar substance, just like the membrane lipids, so if you can get your oil to that cell, it will mix with the lipids within the membrane. The ion channel, which sits in the membrane, too, is rather closed to the membrane interior and opens to the inside and outside of the cell which, contrarily, is a ...

We can consider the classical example of Long Term Potentiation. CREB is a transcription factor which is activated during LTP by phosphorylation. Your reasoning about the delay between signal and transcriptional response is correct and thats why neurons have local translation factories near the dendritic spines and gene regulation (fast responses) is ...
