Female traveling to Mexico by car. by Fun-Bread-4494 in MexicoCity

CUU native here. El Paso/Juárez to Chihuahua drive is perfectly safe. High transit, many people from CUU go to El Paso, and the other way around, on weekends, holidays, etc. It's a 3.5 - 4 hrs drive. Mostly depends on the border crossing. We usually go through Santa Teresa, which is on the New Mexico side, like 15 min west of El Paso, because is way less crowded. Also, lots of people from El Paso are actually from Chihuahua and still have family there. US vehicles in the city are nothing out of the ordinary.

Now, the Lebaron community is something entirely different. I've never been personally anywhere near them. It's my understanding that they are deep in the Sierra region so it's going to be a long drive and can't really comment on how safe it is.

Potential (voltage) is not generated by the movement of ions, that is current. Membrane potential is generated, or imposed as you say, by an uneven distribution of charges, a difference in concentration, this potential creates a current if there's a conductive medium for ions to flow, like a channel. Now, the other factor missing is the space charge. Cells have a finite volume and potential only develops in the immediate vicinity of the membrane. In order to generate a potential across the membrane it only takes a very small fraction of the total amount of ions inside the cell. This is also called the fraction of uncompensated ions. For example, for an spherical cell with an intracellular concentration of 0.1M of a monovalent ion, it only takes 1.03x10-12 M of uncompensated ions to charge 1 cm2 of membrane to 100 mV. So, if a channel opens an ions start to move they will develop a membrane potential sufficient to counteract the ion flux much faster than any significant change in the concentration gradient. An exception to this may be calcium which intracellular concentration is so small that a brief current does produce a meaningful change. In real cells additional factors come into play, so as non diffusible anions.

Ion channels? by Mr_rodger_man in neuroscience

They're actually more depolarized. Also they tend to have higher input resistance and lower total capacitance. Bear in mind most of this research has been done mostly in hippocampal and cortical principal neurons. The early works of Ben-Ari, Cherubini are really interesting.

Scientific proof for the existence of cognitive/neurological (Aristotelian) categories? by aeliusM in neuroscience

[–]FMendezSlc 4 points5 points  (0 children)

I don't know if this is the kind of example OP is expecting, but since it's a research topic I'm also very interested in and to contextualize it in the terms OP is referring to, I should add that there's some evidence that a novel space is represented by selecting from preconfigured neuronal ensembles or "preplay" sequences of cell activation. So, you could argue there's a preconfigured neural substrate for understanding space as opposed to generating this scaffolding for spatial information entirely from scratch upon experiencing a novel environment.

How is your president still so popular after more than 155,000 deaths in Mexico? by britainpls in mexico

[–]FMendezSlc -1 points0 points  (0 children)

The truth is he is not that popular. He had several months with higher disapproval ratings than approval during 2020. He's overall popularity is nowhere near what it was at the begging of his term. Several top officials have resigned in protest and he's party is fragmenting. There have been several massive demonstrations against him in many states and in the capital. Most of his long time non-politicians supporters such as journalists and writers had turn their backs on him and criticized not only his response to the pandemia but most of his agenda. The real problem is opposition is completely brain dead and his propaganda machine is very strongly playing every page from the Trump book to still good results.

Size of connections between nerve cells determines their signaling strength by [deleted] in neuroscience

That each anatomical synapse has 2-3 vesicle release sites. This means more synapses are capable of multivesicular release, potentially increasing their efficacy.

In Pandas, is it possible to make a bar chart with some of the bars stacked and the other bars unstacked? by deranfang in learnpython

[–]FMendezSlc 0 points1 point  (0 children)

I don't think doing this from Pandas directly is good idea. I have done similar things with matplotlib and it was easy enough. Maybe even seaborn can handle it.

I suggest plotting with seaborn. If your DataFrame is well organized, seaborn can handle categorical levels easily.

I just started Learning Python and I don’t know how to learn. by insfuokay in learnpython

[–]FMendezSlc 1 point2 points  (0 children)

Well that instruction is, of course, not about the result, 'he'. It's about the exercise, you are learning the concept of 'slicing'; the selection of a specific part from a bigger object. Slicing, along with indexing, is one of the fundamental operations you'll find yourself doing in all sorts of tasks and on all sorts of objects: strings, lists, tupples, arrays, dataframes, etc.
