when the mice died, the simple environment mice had lots less interconnected neurons in their brain than the complex environment mice.
turns out it wasn't the complex environment that caused the brain development, it was the exercise wheel.
And also explains the diverse array of purportedly efficacious substances.
The purported mechanism of action was not to destroy the verucca, although that was the immediate effect; they didn't try to hit all of them. The purported mechanism was to cause damage that would provoke the immune system; it would learn the properties of the virus, and then attack it wherever it found it.
It worked; all my veruccas disappeared, including ones that hadn't been zapped.
I have to say that this was easily the most-painful medical treatment I have ever undergone. Each targeted verucca got a 5s blast, twice per treatment, over a programme of three treatments. Each blast caused me to scream out loud and swear. I apologised to the podiatrist, saying I hoped I hadn't annoyed her neighbours. She said not to worry, everyone screams and swears. It was like having a sharpened red-hot screwdriver pushed into the sole of my foot.
The pain was only during the jolts; when the treatment was over, I put back on my shoes and socks, and walked home (under a mile).
I can take pain; but I'll fkin scream and swear if I need to scream and swear. Basically, if I can stand the pain and not pass out, then I'd rather not be numb while some sawbones is hacking away at me.
