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.

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

[michaelelbert]

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

This would've helped me out so much in my anatomy and physiology class last semester. 😭

I really like the cutaways to text where the text is on one side of the screen and the image on the other. V nice and clean 🙏

Great information... thank you channel...

_Alternative Title:_ *What Squid Game and Frogger Taught Us About How Money Talks*

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.

2:11 STOP EVERYTHING

KRIS GET THE BRAIN CELL!!!

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

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.

I’m sure Kermit and Squidward didn’t enjoy this episode.

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?

I see you trying to slide squid in the title😉

Did you know that Golgi(the smarter of the 2)didn't believe in neuron doctrine.

Polyps and their tentacles around other polyps . And function of brain wrinkles wonder if brain coral functions as actual brain.

And why could'nt he see electricity alone having Different reactions depending on the Wave length impulse signal patter .
I actually have Trouble seeing chemicals alone. Being responsible for different emotions especially sense hormones are. Chemical signals not reactions

[jabberwockydraco]

Can someone explain Fauci's Dogs?

[XavierAway]

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