‘A good deal of use was made of the cinematograph for purposes of demonstration. It was used to illustrate two communications made by Dr. T. Graham Brown, on behalf  Professor Sherrington and himself. The one dealt with recent observations of rhythmic movements in the mammal, in continuation of the remarkable researches in which Professor Sherrington has been for some years engaged. He had given a demonstration of some of his results on the previous day. Dr. Graham Brown's communication afforded a connected account of the research, which was made much more easy of comprehension by the cinematograph film. A most effective example of the value of the method for demonstration was afforded by a second film, showing recovery after lesions of the motor cortex. The cortical arm area had been destroyed in an anthropoid ape, first on one side and then on the other; the recovery of function in the forelimb was shown in a most convincing manner in the film, the animal being seen to take bits of apple with one hand and pass them into the other until the supply was exhausted, when it turned round and began to put the pieces of apple into its mouth; it was also seen to hold a cup of water and drink from it, and to use its upper  limbs for various purposes in a most natural manner, the whole set of movements being so easily and accurately performed that it would never have been suspected that the animal had undergone any operation.’ (751)
