The most direct evidence supporting the claim about the dissimilarity between neural networks and biological brains is that neural networks' grid-cell-like behaviors arise from programmed rules without biological equivalents.
Step-by-step explanation:
Which finding most directly supports the claim that the approximation of grid-cell activity in neural networks has less to do with similarity between the networks and biological brains than with the rules programmed into the networks? The answer is: A) The rules that allow for networks to exhibit behaviors like those of grid cells have no equivalent in the function of biological brains.
Neural networks are computational models that mimic the neural structure of the human brain. Scientists program these networks with specific rules to perform tasks, but achieving results similar to those of biological grid cells doesn't necessarily mean they operate the same way biologically.
If the rules guiding neural network behavior have no counterpart in biological processes, it underscores the artificial nature of these computational models, highlighting that their success is based on human-defined algorithms rather than biological accuracy.
The probable question can be: 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. D) Neural networks can often accomplish tasks that biological brains do, but they are typically programmed with rules to model multiple types of brain cells simultaneously.
