The mouse’s brain wasn’t damaged as in Alzheimer’s and it suffered no physical or sensory symptoms like the other diseases caused.
It rather seemed that its brain had been cleaned, erased, but not permanently destroyed.
The mouse was able to relearn tasks at the same rate as a baby mouse, it just started over, like rebooting a computer after the hard drive crashed.
All the memory was lost but it still functioned.
It was an exciting development but the problem was he was unable to replicate it in the other mice.
For a week he had failed but yesterday he had discovered the solution.
The serum had to be tailored to the specific mouse it was to be used on.
