Researchers at Harvard University used open-source software tools to build a neural network with an architecture different from that of a zebrafish brain.

The team gave the system some basic rules on how to process temperature changes, and then allowed it to "learn" how to do that for itself.

The researchers were surprised to find that the system learned to navigate in a way that was identical to that of biological zebrafish.

The team compared the artificial network to whole-brain imaging data that showed how every cell in the zebrafish brain reacted to temperature stimulus; it found the artificial "neurons" showed the same cell types as those found in the biological data.
