However, there is doubt about the need for this research, particularly the need to cause such brain damage to the monkeys.
This information was already known from studies in humans. The researchers here could clearly have obtained these results from scanning human brains engaged in visual tasks. It is difficult to imagine benefits from this experiment significant enough to justify the enormous suffering of the animals involved.
It seems some of the testing went on for 9 years, but could hardly have been valid, as at least 3 of the monkeys died in this time.
Another quote that questions the need for this research on the monkeys
Human head injury victims are, sadly, all too numerous, and would clearly be the ideal research subjects ...........countless primates could be spared years of suffering and misery.
