The picture reminded me of one a friend showed me the other day.
She does research on rats, (looking at the effect of various drugs on brain activity).
To build a shield around the implanted brain probes, they use old drinks cans, folded into a Faraday cage (and some mechanical protection as well). This leads to her test subjects running around with what look like elaborate hats made out of old coke and red stripe cans on their heads.
She loves those rats, feeds them, cleans them, looks after them every day, and also sticks probes into their brains and eventually euthanasies them herself so that she knows they didn't suffer. All in order to enhance our knowledge about how brains work. She's happy with that compromise and so am I.
