title: Glutamine synthetase activity in subdivisions of brain of the shark, Squalus acanthias.
abstract: Specific activity of glutamine synthetase in Squalus acanthias (spiny dogfish) central nervous system regions was highest in the cerebellum and lowest in the spinal cord. The levels of activity may relate to the excitability of each region by regulating the glutamate pool.
