Yes and no. Neural nets are somewhat inspired by neurons, but it's a pretty loose relation, and the more NNs improve, the less similar to the brain they look. Individual neurons are much more complex than the nodes of a neural network, and even if research into NNs provides insight into the way the brain works, it may be that the analogues of NN nodes are clusters or regions of neurons, or something more mathematically abstract.
