Exposed: A BUAV investigation into the deliberate infliction of
brain damage on marmosets at Cambridge University. The
BUAV’s10-month undercover investigation into primate brain
research at Cambridge University takes us right into the heart
of the UK's medical research industry. Our investigator secretly
recorded the miserable fate of hundreds of marmoset monkeys
imprisoned inside small, barren cages for their entire lives and
deliberately brain-damaged. The monkeys were used for a mixture
of basic research - curiosity-driven and aimed at simply
'finding out about the brain’, and applied research - trying to
develop a marmoset 'model' of human illness such as stroke and
Parkinson's disease. In the weeks before brain damage was
inflicted, monkeys were trained to perform behavioural and
cognitive tasks. After brain surgery, these poor monkeys were
then made to repeat the tasks again, to see how far the brain
damage had affected their ability to perform them. Water
deprivation and/or food restrictions were often
