Can brain scientists read your mind?

What are you thinking about? You wouldn’t always want the answer to that question available to others, but science may be heading in that direction.

For now, researchers are far from being able to tap into your thoughts. But a new study shows how, just by looking at brain activity, it may be possible to see whether or not you’re thinking about numbers.

“The patient doesn’t need to talk to you. They can think about numbers and you can see that red mark (corresponding with activity in a particular brain region) go up,” said Dr. Josef Parvizi, associate professor of neurology at the Stanford University Medical Center and senior author of the study. The study is published in the journal Nature Communications.
Take note, this study was done on only three people with uncontrolled seizures – that’s a tiny sliver of humanity. But Parvizi said most studies on patients with intracranial electrodes only involve two to five participants, since recruitment is so difficult.

These patients had electrodes implanted in their brains to locate the source of their seizures. Surgeons perform this procedure to isolate or remove the area where seizures begin.

The researchers used these electrodes that had been implanted for locating seizures to investigate brain activity in relation to thinking about numbers, particularly in the parietal lobe. In previous studies, this brain area has been shown to be important to a person’s ability to do numerical calculations.
