Cetacean Brain Research: Need for New Directions

  • Theodore Holmes Bullock
Part of the NATO Advanced Study Institutes Series book series (volume 28)


Whereas neuroscience is a rapidly moving field, characterized by the application of many new techniques, progress in understanding the greatest brains has slowed down in the west and is only forging ahead in a few Soviet laboratories in particular directions. The virtual absence of work on the cetacean brain in the U.S.A. is attributable to a combination of cost, the Marine Mammal Protection Act, and public sentiment against exploiting these animals. Two things need to be said here, in this historic international forum. One is that I support the Marine Mammal Protection Act and believe most of my colleagues do; I am working to extend similar protection to primates. The other is that new research is needed and justified especially on the brain and behavior, albeit with a high threshold of justification, that is, for questions of particularly high significance and to which answers are likely.
