List of species enhanced by the drug Cortexin, which stimulated the reasoning abilities of animals. During the Great Disaster, Grant released the experimental animals affected by the drug, and dumped the Cortexin itself into the stream created by a broken water main. In the ensuing days, animals escaping from the National Zoo drank from that stream and became affected by the drug.
