Michael Levin agrees with the plant neurobiologists that neurons are overrated, and that other cells can do what neurons do, just more slowly. ‘Whenever I’m at a conference with neuroscientists, I like to ask them to define a neuron,’ he told me. ‘They list maybe five things neurons can do, and I point out that every cell in the body can do those things.’ By which he means, and has demonstrated, that all cells can communicate (both electrically and chemically), form networks, and store information. ‘I’m not denigrating neuroscience,’ he said. ‘I’m saying neuroscience is widely applicable way beyond neurons. Neuroscience is no more about neurons than computer science is about your laptop.’ The term ‘plant neurobiology’ does not offend him.
