Question

neural networks are computer models intended to reflect the organization of human brains and are often used in studies of brain function. according to an analysis of 11,000 such networks, rylan schaeffer and colleagues advise caution when drawing conclusions about brains from observations of neural networks. they found that when attempting to mimic grid cells (brain cells used in navigation), while 90% of the networks could accomplish navigation - related tasks, only about 10% of those exhibited any behaviors similar to those of grid cells. but even this approximation of grid - cell activity has less to do with similarity between the neural networks and biological brains than it does with the rules programmed into the networks. which finding, if true, would most directly support the claim in the underlined sentence? choose 1 answer: a the rules that allow for networks to exhibit behaviors like those of grid cells have no equivalent in the function of biological brains. b 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. c 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.

Explanation:

The under - lined claim is that the approximation of grid - cell activity in neural networks has more to do with the programmed rules than with similarity to biological brains. Option A supports this as it shows that the rules for grid - cell - like behavior in networks have no equivalent in biological brains, emphasizing the disconnect between the programmed rules in networks and biological brain functions.

Answer:

A. The rules that allow for networks to exhibit behaviors like those of grid cells have no equivalent in the function of biological brains.
