Can you tell us more about the techniques that you're using? Yeah, absolutely.

So maybe let's start with calcium imaging, right? Because...

If we talk about imaging approaches, there are some sort of pros and cons of that compared with electrophysiology.

Right.

So classically, if you do electrophysiology, you basically you stick an electrode into a single neuron and then you can read out the membrane potential fluctuations.

Right.

And thereby you can see.

What is this? And why is it important? And what did you find in this kind of connection between these two regions?
