I think most of you will agree, though, that the photo simply feels fake
I was surprised they didn't simply go for "you can tell by the pixels."
On a real track, the rat's version of that neuron would fire when it had taken two steps away from the start, and then again when the animal reached the same spot on its return trip. But in virtual reality, something odd happened. Rather than firing a second time when the rat reached the same place on its return trip, the cells fired when the rat was two steps away from the opposite end of the track
See there is value in testing the obvious.
