Can this be extrapolated to video games?

Stellenbosch University.

Admittedly, it is pretty much because "its Harvard". A did a search and it came up ranked number 1 in terms of neuroscience departments. I am somewhat ambitious, so it may be more for the prestige. Of course, if another university has a better department that is more appropriate to my field of research, then I won't hesitate to go there instead.

I've been fascinated by UFOs, ancient civilizations, the unexplained, ancient artifacts since I was a kid. I've "researched" these things with the best of my ability and have concluded that multiple alien species live around and among us. I think some UFOs are ET ships and others could be celestial beings.
Here are some interesting videos about UFOS and the like. good ones first, iffy ones towards the bottom

It takes an open mind, time and your imagination with this kind of stuff since we dont have much/if any hard evidence. you have to sift thru a lot of BS and make up your own mind.

Why the fuck do unmyelinated axons with larger diameters conduct action potentials faster?

I can't wrap my head around it. Sure, if you have a larger diameter, then that means more overall membrane, which means more ion channels, allowing a larger amount of ions to cross the membrane at any one time, increasing the current, which makes the membrane reach the threshold potential faster.

BUT CONDUCTANCE IS FUCKING LATERAL, isn't it? I mean, its along the membrane. An axon depolarises depending on the activity of the ion channels directly adjacent to it. So wouldn't it be a case of ion channel density that increases conduction velocity?

Not homework, not asking /sci/ to do shit for me, just reading up on this shit and can't seem to understand this little part right here.
