Anxiety-like behavior in invertebrates opens research avenues

For the first time, researchers have produced and observed anxiety-like behavior in crayfish, which disappears when a dose of anxiolytic is injected. This work 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. Anxiety can be defined as a behavioral response to stress, consisting in lasting apprehension of future events.
