Are you saying that the only reason the wild mice did poorly is that they've forgotten that they received a painful stimulus seconds after they received it? It's pretty clear that whatever they are, short term memory has a different mechanism than long term memory, Tang made no claim that Doogie mice were better at it nor is there any reason to thing that the observed increase in LTP has anything to do with short term memory.

Doogie doesn't remember everything indiscriminately, it knows when forgetting an old idea is useful. I'll grant you that a mouse can not write a sonnet but you must grant me that a mouse has an intelligence greater than zero, if you don't like the ones used in the paper what test would you recommend to measure it?

Theories are a dime a dozen, the idea that Long Term Potentiation and long term memory are synonymous has been kicking around for decades but until recently the evidence in its favor has been almost zero.

I can find no mention of humans in the paper, the closest was the very last sentence:

I predict that the first application of this technology (otherthan research) will be in pets, it shouldn't be much harder to do this to a dog and a unusually intelligent breed of dogs might have considerable commercial application. If the breed is cute and cuddly it might improve the image of genetic engineering too.
