The GABA neurotransmitter is responsible for inhibiting specific brain signals, decreasing nervous system activity.
When GABA neurotransmitters attaches to their receptors in the brain, that reduces stress and anxiety, producing a calming effect.

The goal of the study was to analyze which "biological processes control the development of the sea anemone," and found the similarity with the human brain.
“In the study, we not only discovered that a receptor from the GABABR [GABA] family controls the metamorphosis process in the sea anemone, but also that the molecular path is similar to that found in humans, and in both cases it mediates nervous system functions," stated the researchers.
