Because in the usual context of discussion, a "neural network" or NN is considered to be a relatively homogeneous, uniform structure equipped with a relatively systematic learning procedure. The brain is at least 400 different architectures interconnected in accord with genetic specifications that appear to involve the order of at least 30,000 genes. So the performance of brain-NNs does not constitute an existence proof for ways to solve similar problems by homogeneous NNs.
