To access the data, click or select the words “Appendix 1.” This will initiate the download of a Microsoft Excel (.xls) file. All probes determined to be differentially expressed by the experimental threshold criteria are shown with their associated Gene Ontology Biologic Process terms. Index refers to the microarray spot position. Fold-change is indicated for the response of the Li⁺ treated samples versus controls as an average value across all four arrays. Signal strength (A) is shown in log₂ scale and is calculated as the average across all four arrays with 7 considered as the minimum threshold for which the target transcript is considered detectable. Gene Ontology terms that are associated with the gene are indicated by the green boxes.
