Hi,
Since the definition of "consciousness" in any organism has still not been boiled down to specific mechanisms, it is difficult to address directly.
Instead, the approach we are following is that we are using computer simulations to reproduce the biophysics that are known about the worm's biology. By assembling as many simulated biophysical phenomena as we know about into a single computer model, we aim to build a model that has behavior that closely matches the real organism. Where the behavior is different, we identify that as a "gap" and do more research and data collection to fill it in. And then we iterate.
As to whether the end product is conscious will be up to others to decide. Our standard is reproducing the biophysics of this particular living system in a way that you can measure and compare the measurements to the real thing.
Why this takes so much effort is that putting all the data and biophysics in place so everything interacts appropriately, otherwise known as the modelling process, requires setting a lot up and integrating a lot of data. Then there is all the testing that needs to happen to make it all come together.
Thanks,
Stephen
