Here is a quick python-port of Dimitri Yatsenko's MATLAB code for Trippy:

The code produces three movies at three contrast levels (feel free to change).

Thanks to Dimitri for sharing!

It works indeed!

Very disturbing stimulus. I am having a hard time pointing at what it evokes. It feels like the sense of space somehow disappears.

Here is a first attempt at using the same Gaussian filter that underpins Trippy and apply it to Zebra:

@jeromelecoq Can you send me the monitor dimensions in pixels (e.g., 1,920 x 1,080), so I can create the movies in appropriate format? You can also just send me the monitor brand and type and I can go find out.

Hi @maierav, Yes, the screen is positioned 15cm from the mouse eye, we typically display movie (1920, 1080) at 30 or 60Hz. The frame rate will depend on how performant is bonsai with replay here. I can try both to confirm.

The microns team actually has an inhibitory mouse, ie. functional data + EM data! The data is not currently analyzed but they say it is public. That means, we might be able to test some of our ideas here.

[jeromelecoq]

This means the response to trippy was recorded there! We could just analyze it to see if sub-groups emerge.

I used @maierav efforts and some conversation with the team to generate our zebra movies, given our changing geometry :

I am going to ping the team to comment on this, to make sure I am doing this right.

This looks good to me!
