Evidence of Ancient Brains
Monday, November 9, 2015
A fossil creature buried in an "invertebrate version of Pompeii" more than half a billion years ago reveals an exquisitely fossilized brain. "This is the oldest preserved brain of any kind," said Nicholas Strausfeld, a Regents' Professor of Neuroscience at the University of Arizona's Department of Neuroscience, who identified the brain as typifying that of a modern mandibulate arthropod, thus virtually unchanged for at least 520 million years. Neuropaleontology is now an important part of research on brain evolution.

Neuro-Imaging Fossils Reveals Evolutionary Relationships
Tuesday, October 29, 2013
CNN talks with Regents' Professor Nicholas J. Strausfeld about ground-breaking work to reveal the nervous system structures of 500 million year old fossils. This work shows both early evolutionary differences among arthropods and suggests evolutional links between spiders and crustaceans. Read the CNN article and the full findings as published in the October 17th issue of Nature.
