Answer 1

The question is asking which finding would most directly support the claim that the approximation of grid-cell activity in neural networks has less to do with similarity between the neural networks and biological brains than it does with the rules programmed into the networks.Option A states that the rules that allow for networks to exhibit behaviors like those of grid cells have no equivalent in the function of biological brains. This would directly support the claim because it suggests that the behavior of the networks is not due to their similarity to biological brains, but rather due to the rules programmed into them.Option B suggests that the networks that do not exhibit behaviors like those of grid cells were nonetheless programmed with rules that had proven useful in earlier neural-network studies. This does not directly support the claim because it does not address the similarity between the neural networks and biological brains.Option C suggests that once a neural network is programmed, it is trained on certain tasks to see if it can independently arrive at processes that are similar to those performed by biological brains. This does not directly support the claim because it does not address the similarity between the neural networks and biological brains.Option D suggests that neural networks can often accomplish tasks that biological brains can. This does not directly support the claim because it does not address the similarity between the neural networks and biological brains.Therefore, the answer is A.
