Brain Stimulation Creates Creepy Sensation
Interesting report on specific brain stimulation producing the sensation of being watched or followed. Here’s an excerpt from the news release of the finding, reported in Nature:
When they electrically stimulated the left temporoparietal junction in her brain, which is linked to self-other distinction and self-processing, she thought someone was standing behind her.
If they repeated the stimulus while she leaned forward and grabbed her knees she had an unpleasant sensation that the shadowy figure was embracing her.
I wasn’t really familiar with the temporoparietal junction being associated with self-other distinctions, but there you go. I’m curious to know what purpose this might serve evolutionarily, and why we may sometimes be accurate in those perceptions. As they say, you’re not really paranoid if they really ARE out to get you.
