| Abstract: | Abstract— Neutron activation analysis was used for the simultaneous determination of copper, manganese and zinc in the brains of calves, cows and pigs. Measurements of these three elements in as many as 11 different regions of the brain showed that the highest content is always found in the pineal body. Typical values for calf brains are: Cu, ∼20 μg/g; Mn, ∼3 μg/g; and Zn, ∼90 μg/g dry pineal tissue. As a first approximation, the ratio of Cu:Mn:Zn is roughly constant for all regions. |
