I think it's important to see all of these situations. The very fact that the brain optimizes its maps based on constrained environments is awesome. Also, the technology had to be built to do the previous 2d studies, which then bootstrapped the 3d studies. Knowing that under certain circumstances the neural maps had a very "clean architecture" may have saved a lot of time and effort once these more random 3d structures were being analyzed.
- doodlebugging 5y agoI agree. This is awesome work and is a great starting point. The regular gridding to me indicates that the rats learned the routes and found them easy and maybe even boring so after a point, they were not challenged intellectually in the navigation. Once their environment was modified, the rats began to engage more of their brain to learn and manage the choices that each situation required. I just thought it was funny that the researchers were surprised to see such a large difference in how rats handle complexity when we know going in that rats are pretty intelligent. Those rats probably know each researcher, have favorites, remember routes, and get bored with those tasks like we would be. It becomes muscle memory for them so they go through the motions to get the treat they know is waiting.
