Husbands has edited several books, including coediting The Mechanical Mind in History (MIT Press; 2008; ISBN978-0-262-25638-4) as well as author of numerous scientific articles. With neuroscientist Michael O'Shea he introduced the idea of GasNets – artificial neural networks that use diffusing virtual gases as modulators. These are inspired by nitric oxide (NO) volume signalling in real brains. The Sussex team has also done pioneering work on detailed computational modelling of nitric oxide diffusion in the nervous system.
