Positron Emission Tomography (PET) is a groundbreaking detection system that, among many other applications, enabled neuroscience researchers to detect and image physiological changes in the brain associated with cognitive operations as subjects perform a task. This technology helped researchers learn to explore the physiological basis of human cognition in new ways and was the immediate forerunner of functional Magnetic Resonance Imaging (fMRI), a technology that continues to dominate the neurosciences. PET was also the founding invention of a new field of cognitive science: human functional neuroimaging. Indeed, some would say that PET encouraged a particular way of understanding the brain …
