Timeline of treatment with CAW and behavioral experiments. Three cohorts of NRF2KO and WT mice were treated with CAW (2 g/L) at 5 months of age; the first group was cognitively tested at 6 months, the second at 12, and the third at 18. Following behavioral tests, mice were euthanized, and tissue was collected.
