Botox Feeback

A study finds delayed reaction times to unpleasant emotion in people who’ve had Botox treatment, supporting something called the “facial feedback hypothesis.”

[A]fter Botox treatment, the subjects took more time to read…angry and sad sentences…“Normally, the brain would be sending signals to the periphery to frown, and the extent of the frown would be sent back to the brain. But here, that loop is disrupted, and the intensity of the emotion and of our ability to understand it when embodied in language is disrupted.”
