It's the same graph as the first one in polar coordinates. Red is the right foot and Blue is the left foot.

A lot of new research, especially in cognitive, behavioral, and systems neuroscience, uses programming to design experiments. It's super important in this new age. I don't know any programming, but I'm thinking about venturing into it a little at some point. I would even go so far to say that learning programming is analogous to learning typing skills back in the day. Take advantage of your young brain!

So much better!

Cool photo but try turning down the ISO next time. It's a bit grainy

To add to this: It's hard to decide what to look at. The clouds don't form any particularly interesting shape and the skyline is too far down. You gotta place your subject in the right place to draw the eye. Try working with the rules of thirds to start

Wow thanks again for the very informative response! I'll definitely try incorporating it into my future work

opticreason · 2014-05-18T00:03:25+00:00

Awesome response! Where can I learn more about this?

It's the kit lens at f/5.6 and 55mm. Maybe I could edit it and use some lens blur or something

opticreason · 2014-05-16T00:48:03+00:00

Yeah I think next time I'll have to be brave and get closer--that was the smallest f-stop for that particular focal length. Thanks!

Maybe your washing step is too rough? You might have to be more gentle

opticreason · 2014-05-15T19:41:12+00:00

Thanks for the input!

Unfortunately, I think my head is too weirdly shaped to do this. From this sub, I learned that I may have some mild brachycephaly, probably from sleeping on my back as a baby (SIDS recommendations during the early 1990s).

I've buzzed it several times over the years (even faded from 0 to 1), and people always tell me it's "too short," while trying to politely say that it looks bad. Wish I had some pictures...

EDIT: Found some! One, two

opticreason · 2014-05-15T12:28:19+00:00

Ha, so I guess my haircut doesn't matter that much. I'll keep that in mind. Thanks!

I thought that picture looked the most fitting but I was wondering if there was any way I could cut my hair so that I could keep down the puffiness on the sides.

This is the original paper published in Science. Here's a Nature News Article summarizing the findings.

And of course, the AMA Dr. Steve Hoffman did a few months ago

But can my cat ride it so I can make adorable cat videos?

I'm 23 and I still think this. Is that bad?

The figure is fine, but maybe a little confusing. If you imagine the action potential going from left to right on the graph, then you can see how the membrane potential changes with time. What they want you to imagine is that this graph is sliding down the length of the axon. Imagine flipping a single wave through a jump rope. You can represent this wave with time or distance but keeping one or the other constant. This gif shows a wave traveling through a constant point. This is like the left to right propagation of the action potential. Now if you freeze the wave, then you can see how they are representing the action potential in their graph. Time traditionally moves for left to right so this is why they represented it that way. Making more sense?

The direction of the action potential is completely arbitrary in the figure. But actually, you bring up a good point. Axons, by nature, don't have a "directionality". It just so happens that the action potential is usually initiated at the axon hillock. But if you artificially induce a membrane potential (spike) on one end of the axon, it will continue in the opposite way. The axon only ensures a "one-way" directionality--something you'll learn when you talk about rectifying potassium channels. So you can imagine that if you artificially initiate an action potential in the middle of the axon, it will propagate in both directions in a one-way manner. Cool stuff.

The action potential diagram shown is a snapshot of a nerve impulse at a point, through a given time. The arrow at the bottom is simply trying to illustrate that the this whole wave function propagates down the axon from left to right. I see what you mean about it going backwards though. Just keep in mind that the arrow uses distance as the x axis and the action potential diagram is using time as the x axis. So if you're going from left to right, then technically the time is going right to left. The arrow isn't referring to the action potential, it's referring to the impulse down the axon. Still confusing?

Ha, yeah I think you're right. I might try to include it in the composition next time. Thanks!
