Marmoset Sleep Deprivation Study Ends After Only One Night

After pressure and complaints from PETA, a sleep fragmentation experiment that University of Massachusetts–Amherst experimenter Agnès Lacreuse had moved to the University of Wisconsin–Madison’s Wisconsin National Primate Research Center ended. UW-Madison had received approval to subject 32 marmosets to 24 nights, over two months, of loud, blaring noises to wake them repeatedly. Instead, six marmoset monkeys were sleep-deprived for one night.
