The researchers have developed new analysis methods to evaluate neurotransmitter concentrations in the brains of normal and genetically modified mouse models for Alzheimer's disease (AD mice) and their study of AD mice shows that the high concentration of the GABA neurotransmitter in the reactive astrocytes of the dentate gyrus correlates with the animals' poor performance on tests of learning and memory.
