<\/div>MOOD RING<\/h2>
How are researchers supposed to know if the subjects of their experiments are happy, sad or depressed? A patient’s own description, presumably, sometimes just doesn’t cut it. A team of neuroscientists figured out a way<\/a> to read a person’s mood by analyzing their brainwaves. It’s more than just a party trick — it’s first time scientists have made an explicit connection between brainwaves and emotional states, and it could have far-reaching implications for the future of treatments for mood disorders.<\/p> They describe their technique in study published Monday in the journal Nature Biotechnology<\/em><\/a>.<\/p> The scientists worked with seven volunteer subjects<\/a> whose brains had already been implanted with electrodes as part of their treatment for epilepsy.<\/p> Over the course of several days, researchers collected neural signals from those patients’ implants, as well as questionnaires about the patients’ moods.<\/p> The brainwaves associated with a particular mood looked different in each patient, the researchers found. But the scientists were still able to create software that finds correlations between a patient’s brainwave data and corresponding questionnaire. Eventually, it could infer that patient’s mood by analyzing the neural signals alone.<\/p> Granted, this study only included a handful of patients (those with sensitive detection devices already embedded in their brains, at that) over a short period of time. And the researchers didn’t figure out precisely why<\/em> certain brainwaves were associated with particular moods<\/p> Still, though, the researchers believe their work could pave the way for treatments that build on deep brain stimulation, a technique in which an implant stimulates the brain to treat conditions such as obsessive compulsive disorder and major depression.<\/p> Farther into the future, though, such an implant could keep tabs <\/a>on a patient’s emotional state — and, if it detected an abnormality, give them a jolt to help bring them back to normal.<\/p> READ MORE: <\/strong>We’ve cracked the brain’s emotion code and it may help depression<\/a> [The Wall Street Journal<\/em>]<\/p> More on brain implants: For the First Time Ever, Scientists Boosted Human Memory With a Brain Implant<\/a><\/em><\/strong><\/p> The post This Device Reads Your Brainwaves to Figure Out Your Mood<\/a> appeared first on Futurism<\/a>.<\/p> View post: MOOD RING How are researchers supposed to know if the subjects of their experiments are\u00a0happy, sad or depressed?
