Replacing fMRI with a slightly less accurate technique called near-infra-red spectroscopy produced two further successful trials involving a different volunteer.

ECONOMIST: Reading the brain

In later life, Snow insisted that by vocation he was a writer, though he trained as a chemist and did important research in infra-red spectroscopy the main tool in the 1920s and early 1930s for unravelling the structure of molecules.

ECONOMIST: Science in fiction is not science fiction

The first two were carried out with an FT-IR system, so using infra-red light, and the other using Raman spectroscopy.
