’Brain signature’ that predicts human emotions discovered

Researchers have discovered a way to predict human emotions based on brain activity. The study is unusual because of its accuracy — more than 90 percent — and the large number of participants who reflect the general adult population rather than just college students. The findings could help in diagnosing and treating a range of mental and physical health conditions.

this study is interesting in that a signature can be found for pain

In their new study, the researchers’ goals were to develop a brain signature that predicts the intensity of negative emotional responses to evocative images; to test the signature in generalizing across individual participants and images; to examine the signature’s specificity related to pain; and to explore the neural circuitry necessary to predict negative emotional experience.

> to examine the signature’s specificity related to pain

I’m reading about pain at the moment. I’m up to pain receptors – Pacinian corpuscles, Meissner’s corpuscles, Ruffini endings, Merkel’s disks, nociceptors, A-delta mechanical nociceptors, C-polymodal nociceptors. And chemoreceptors for potassium, serotonin, bradykinin, histamine, prostaglandins and substance P. It’s a good book.

(PS. I’m amazed that the spell-checker accepted all the above as valid English words)

I haven’t got to the part on emotional pain yet.
