[[Selenium|Sodium Selenate]] (Na2Se04) activates PP2A (1).

* [[CTA and Selenate]] experiments show that male Sprague Dawley rats given systemic injections of 0.5mg/kg sodium selenate two hours before taste aversion conditioning form attenuated taste aversions that extinguish rapidly. Selenate also decreases LiCl-induced phospho-MAP kinase in the NTS and lateral PBN.

Results suggest that selenate interferes with the regulation of learning-induced intracellular signaling by PP2A, and prevents consolidation of memories acquired during CTA learning. However, an alternative explanation is that sodium selenate affects LiCl-induced malaise and prevents the rats from associating the conditioned stimulus (saccharin taste) with LiCl by dampening the effects of LiCl toxicity.
