In Vitro	The endogenous neurosteroid Tetrahydrodeoxycorticosterone (THDOC) at physiological concentrations selectively enhances tonic currents mediated by αβδ receptors[1]. In hippocampus, 10 nM Tetrahydrodeoxycorticosterone reduces neuronal excitability by augmenting tonic αβδ receptor currents. In thalamocortical neurons, although 100 nM Tetrahydrodeoxycorticosterone enhances tonic currents, 10 nM Tetrahydrodeoxycorticosterone does not[1].
In Vivo	Concentrations of Tetrahydrodeoxycorticosterone (THDOC) in brain tissue from mice with hepatic encephalopathy (HE) resulting from toxic liver injury are sufficient to induce sedation in animals of the same species[2].
