facial expressions, mirroring and Botulinum toxin

Source

New information that I could not have imagined from the amazing book that I read, The Brain. Story of us.

He talks about Botulinum toxin

that people inject to prevent facial wrinkles. It is made of a toxic substance that causes paralysis. This substance paralyzes the facial muscles to prevent the appearance of wrinkles.

One of the negative side effects of this topic is that the person who is injected with Botox loses the ability to use his facial muscles and cannot show any of the facial expressions that express different emotions.

It also turns out that they lose the ability to distinguish the different feelings of the people they deal with.

From the experiments that were conducted on this subject, it became clear that when a person sees any of the signs of the face, he makes the same sign on his face. I mean, if someone sees a smile, he will smile too, and this act is subconscious and unconscious. A person who has lost the ability to use his facial muscles loses the ability to mirror the sign he sees in the person he deals with, and this loss of mirroring ability makes his brain unable to understand the facial signs of the person he deals with.

I mean, Botox makes a person not able to express his feelings through facial expressions, and he also loses the ability to understand the facial expressions of the people he deals with.

Although it has positives for certain pathological conditions.
