Brain structures devoted to learning and memory are highly
conserved in the animal kingdom, suggesting a common evolutionary origin.
It turns out that the structure and function of brain
centers responsible for learning and memory in a wide range of invertebrate
species may possibly share the same fundamental characteristics, according to a
new study published in the journal Current Biology and performed by University of
Arizona neuroscientists Nicholas Strausfeld, Regents' Professor in the
Department of Neuroscience, part of the UA's School of Mind, Brain and
Behavior, and Gabriella Wolff.
