Strongly positive nuclei were also present in the dentate gyrus and pyramidal cell layer of the hippocampus.
.. ", together with paralytic, neurotoxic, diarrhetic and ciguatera fish poisoning (FDA website: http://vm.cfsan.fda.gov/~dms/haccp-2f.html) [ 14 ] . Recent behavioral toxicity studies in rodents, have confirmed that domoic acid is a very rapid and potent neurotoxin in newborn rats, at doses far lower than in adult animals [ 15 16 17 ] . Even though hippocampal pyramidal neurons and mossy fiber terminals appear to be selectively targeted in vivo by domoic acid in rat [ 18 ] and cynomolgus monkey brain [ 19 ] , recently domoic acid was shown to affect glutamate uptake by astrocytes in vitro and " ...thus produced neurotoxicity.
In this manner, inactive cells are brought closer to threshold, enhancing their opportunity to firing together [ 29 30 31 ] . The extracellular resistance is the major determinant of field-effect strength [ 32 ] . Since the extracellular volume fraction in CA1 stradium pyramidal is only 12% compared with approximately 18% in CA3 and granule cells [ 33 ] , the CA1 pyramidal cells are particularly susceptible to field effects.
Thus, for example, in the former, we found NK-ir fibers in the superior colliculus, the restiform body, the pyramidal tract, and in the pontine nuclei, in which in the cat no immunoreactive fibers were found [ 15 ] . Comparing the distribution of cell bodies containing NK in both cat and human brainstems, it seems that the distribution is widespread in the feline (see [ 15 ] ). In both species NK-ir perikarya were found in the periaqueductal gray and in the inferior colliculus.
The variation in neuron-packing density with volume contrasts somewhat with the report of Abusaad and colleagues [ 36], who found no significant differences (P = .06) in neuronal packing density in the dentate gyrus cell layers of the hippocampus among the three mouse strains that they examined, but did see a significant difference in the pyramidal cell layers.
