Anxiety in invertebrates opens research avenues

For the first time, CNRS researchers and the Université de Bordeaux have produced and observed anxiety-like behavior in crayfish, which disappears when a dose of anxiolytic is injected. This work, published in Science on June 13, 2014, shows that the neuronal mechanisms related to anxiety have been preserved throughout evolution. This analysis of ancestral behavior in a simple animal model opens up new avenues for studying the neuronal bases for this emotion.
