Zinc Deficiency Leads to Lipid Changes in Drosophila Brain Similar to Cognitive‐Impairing Drugs: An Imaging Mass Spectrometry Study

Several diseases and disorders have been suggested to be associated with zinc deficiency, especially learning and memory impairment. To have better understanding about the connection between lipid changes and cognitive impairments, we investigated the effects of a zinc‐chelated diet on certain brain lipids of Drosophila melanogaster by using time‐of‐flight secondary ion mass spectrometry (ToF‐SIMS). The data revealed that there are increases in...
