Marmosets Harmed in Neuroscience Experiments




Marmosets were forcibly restrained and made to undergo surgery, during which researchers drilled holes into their skulls and inserted probes into their hearts. The marmosets were also injected with substances targeting the brain. The ostensible goal was to investigate which regions of the brain modulate anxiety and the experience of pleasure. However, the extreme procedures inflicted severe and prolonged suffering on the marmosets solely for the aim of non-essential scientific curiosity.
