This research is particularly fascinating because years ago Candace B. Pert PhD believed that each core emotion might be associated with a specific neuropeptide, while news in the British Medical Journal the Lancet suggested that emotions and feelings represented not only different concepts but also followed different pathways in the brain. According to Thomas Ethofer, previous research methods analyzed increased brain activity at individual locations. This study looked at overall patterns of activity. He has been reported as saying, “Consider the following analogy. If you have a puzzle consisting of black and white pieces, it is hard to say whether they belong to a picture of a zebra or a checkerboard if you look at each piece in isolation, but it becomes relatively easy if you put the pieces together.” Brilliant!
