When rats gaming championships become a thing, I will have the top team for sure! Seriously though, this project took way too much time. We built 2 versions of the setup, lots of hardware, software building, testing. I hope a behavioral lab or hardware enthusiasts would take it over and scale it. I did learn a lot in the process and would gladly support anyone who would continue it. In fact, I have a setup now laying around in my living room up for the taking :D
Seriously impressive work, and I do hope someone runs with the torch, it's always fascinating to see what our little rodent buddies are capable of.
Even if you're sort of like an alien abducting them for experiments.... if you offered me a sugar drip to play doom in VR, I'd be there
