then we also have these accelerometer signals so there's a there's a hypothesis that comes from the computational work that says well we should be able to decode you see friends copy signals in you know potentially even in v1 and it turns out that that is exactly what we can do so so these blue bars are in complete darkness and visual cortex so there's no visual stimulus they're not getting any visual optic flow but we can decode a little bit of you know sort of six degree of freedom information about which way the animals
