eLife assessment
This paper measures the neural activity in reach-to-grasp and reach-only tasks using intrinsic optical imaging. The paper describes these in the relationship to the Intra-cortical micro stimulation maps of the same animals. The dataset is unique and potentially highly important. However, the claim of "clustered neural activity" is not tested against any quantifiable alternative hypothesis of non-clustered activity, and support for this idea is therefore currently incomplete.
