What Squids and Frogs Taught Us About How Brain Cells Talk

Back in the early days of neuroscience, we didn't study the animals you might expect to learn about how brain cells communicate.

The study of frogs really helped neuroscience hop forward.

Do they study live frogs, or wait until the croak?

Thanks for the clarification Hank! I also feel responsible for that, it could be a coincidence. Either way I'm proud 😁.

Please enlighten me as to where and how is a thought initiated, to begin the action potential. I want to thank the whole sci show team- and am so grateful for each video y’all produce. Thanks

I remember animator Amy Winfrey made a series called Squid & Frog, starring a squid character and frog character. I wonder if she knew about those unique features and association with each other.

[@NewMessage]

And yet, still no Squidfrog. Come on, science. get on it!

[@PhillipAmthor]

But first the catgirls

[@protohale]

Until recently, we only knew how brain signals got from one cell to the next. In a cell, an ion movement gives that part of the cell membrane a different electrical charge, which then moves like a wave down the cell's axon. When it initiates communication with another cell, the membrane opens, allowing sodium to enter and potassium to exit, resulting in an action potential. The action potential allows one cell to signal to another, and sometimes the receiving cell becomes more active, but at other times it's subdued.

Hi

[@gmsherry1953]

I would almost bet money (and I don't gamble) that in the late 19th and early 20th centuries, Santiago Ramon y Cajal didn't have to justify squat to "oversight committees, research institutions, funders, and publishers." That sort of sensitivity is a recent invention. Have you ever seen what Pavlov did to those dogs? Or think of what Zimbardo did to human beings (the Stanford prison experiment). Or consider the Tuskegee Syphilis Study. It's all well and good to try to reassure your viewers that NOW we have safeguards and guardrails, but to segue directly into discussion of research from earlier times is inaccurate. Isn't it?

[@KY_CPA]

Not for regular viewers. They have a whole episode of Experiments that wouldn't be allowed in modern times. Don't remember if it's on Scishow or Scishow Psych

[@KY_CPA]

Here's the link to that episode. It's here on Scishow

0:54 so you can do the research but can't publish it if the use of animals can't be "justified"?

[@scorpioneye1]

The sentence was poorly worded. The oversight committees, research institutes, and funders all have to approve the usage of animals before it is allowed. Justifying using an animal includes not only why the research is necessary but also why it cannot be accomplished through simpler means such as in lab grown cells.

[@michaelelbert5798]

And still Hank and SciShow team don't mention ethics or morality of using animals for testing. Aside from that one CrashCourse philosophy episode.

[@KY_CPA]

SciShow is meant to present findings and studies and scientific concepts. Ethics and morality are Philosophy by definition, and thus outside the scope of this channel.

[@TheZenytram]

yeah, ethics have shown down science a lot, its a shame.
