TABLE 2.
Abundance and distribution of amyloid‐beta peptide (Aβ), detected by antibody mOC64, in all available sections of the brains of three odontocetes (Gm1, La5 and Tt1) with amyloid plaques present and one (Gm5) with no amyloid plaques present, and the two selected sections of cerebral cortex from the four younger, control, odontocetes (Gm6, Gm7, La6 and Tt2)
