2. Effects of neuroactive steroids on the recombinant GABAA receptor in Xenopus oocyte
Abstract : Introduction: Neuroactive steroids represent a class of both synthetic and naturally occurring steroids that have an effect on neural function.

4. Sex and stress steroid modulation of GABA mediated chloride ion flux in rat CNS
Abstract : Background: Sex and stress steroids are metabolized to 3a-hydroxy-pregnane-steroid metabolites such as allopregnanolone (Allo) and tetrahydrodeoxycorticosterone (THDOC). Allo and THDOC are neuroactive steroids that are metabolized in the brain and act in brain as potent positive GABAA receptor function modulators. READ MORE
