And here's here's what some of these uh patterns look like.
First of all, this is something we call the electric face.
So again, here's a time lapse of a frog embryo putting its face together.
And there's a lot going on here.
But if you look at one frame of that uh video, you can see that prior to the appearance of the craniofacial organs, this is the map that it's going to build.
Here's where the animal's right eye is going to go, here's where the mouth is, here are the placodes.
So this we are we are literally what you are seeing here is literally reading out the electrical memories that tell.
The cells, what a correct face is supposed to look like.
And this is what guides uh normal, normal development.
So we can now begin to read out what it is that uh that these cells remember as the correct thing to build.
And not only does this uh bioelectricity serve as a kind of cognitive glue that binds individual cells into a global vision of what the whole large-scale thing is supposed to look like, it actually does this for multiple embryos.
Here you can see if we poke this embryo, all of
these guys find out about it.
Okay.
See this?
So so this this injury wave.
So so so the this bioelectrical communication um uh tends to merge uh subunits into a coherent whole.
And you can see here these are individual cells.
By the way, the way that we are uh monitoring all of this is with uh voltage sensitive fluorescent dyes.
That's a technology that uh that we've developed uh to use um use these dyes to uh uh help understand what the collect the cellular collectives are thinking.
