FDA Warns Companies Over Illegal Marketing of Botox and Related Products.

FDA-approved botulinum toxin products carry a boxed warning indicating the product may cause symptoms of botulism, which attacks the body’s nerves and causes muscle weakness that can lead to difficulty breathing and even death.

Modulation of amygdala activity for emotional faces due to botulinum toxin type A injections that prevent frowning.

Published Scientific Reports, 2023 Feb 27;13(1):3333. Department of Neurobiology and Behavior, University of California Irvine.

Ten females viewed pictures of happy and angry faces during two fMRI scan sessions: one prior to and one following onabotA injections. Found modulation of activity in the amygdala for both happy and angry faces, as well as modulation of activity in the fusiform gyrus for happy faces.

Modulation of amygdala activity (PubMed listing).

Published Scientific Reports, 2023.

Preventing frowning through inhibition of glabellar muscle contraction altered amygdala processing for emotional faces. The modulation of amygdala and fusiform gyrus activity following onabotA may reflect compensatory processes in a neuroanatomical circuit involved in emotional processing.
