Weight rats

1. 1. Schedule:

(Stagger pairs of rats by 20 min to allow time for perfusion)

at 0h, inject with either 1 ml/kg vehicle (0.15 M NaCl) or 0.5 mg/kg Na2SeO4

at 1 h, inject with either 12 ml/kg NaCl or 12 ml/kg LiCl (0.15 M)

at 2 h, overdose with Sleepaway and perfuse

Dissect brains, postfix for 2 h in 4%PFA, rinse with 0.1 M PB, cyroprotect in 30% sucrose
