People who took a basic caffeine pill did not experience the same sort of brain boost they did from sipping a cup of coffee, according to brain scans. Caffeine alone does activate some regions of the brain associated with readiness to tackle tasks, the researchers said. But the act of drinking coffee produced a more comprehensive response in the brain, the results showed. “Taking into account that some of the effects that we found were reproduced by caffeine, we could expect other caffeinated drinks to share some of the effects,” said lead researcher Maria Picó-Pérez, a postdoctoral researcher with Jaume I University in Spain. “However, others were specific for coffee drinking, driven by factors such as the particular smell and taste of the drink, or the psychological expectation associated with consuming that drink.” For the study, researchers recruited a group of people who typically drink at least one cup of coffee daily. They asked these folks to refrain from eating or drinking caffeinated beverages for at least three hours before going into the lab. Researchers then performed two brief functional MRI (fMRI) scans, one before and another a half-hour after the participant took either a caffeine pill or drank a cup of coffee.… read on > read on >
