...first recruited a group of nine healthy adults and presented each with a list of eight beverages, which they were asked to rate in appeal on a scale of 1 to 5. The investigators then outfitted each participant with a headband equipped with fiber-optic strands that projected infrared light through the scalp and skull and into the prefrontal cortex, a brain area critical for processing preference. Infrared imaging is typically used to detect heat, which is just what the researchers were looking for. The volunteers were shown pictures of different pairs of drinks from their original list and asked...
...first to experiment with a technique like this. In the terra incognita of cognitive research, brain-computer interfaces are increasingly common - but complicated. Typically, subjects have to be trained to use them and must rehearse a random, energy-intensive brain task like mentally singing a song in order to light up a pattern of brain activity that sends a signal to the researchers. The new technique extracts information much more directly by targeting the frontal lobe's preference functions. What's more, while other studies have required the subjects to activate their brains over and over again so that researchers...
