GlyR characteristics

Brain area	Expression, nA	EC50, μM	Hill coefficient	IC50, nM
Encephalon	115  ± 35	611  ± 77	2.0  ± 0.5	56  ± 3
Midbrain	346  ± 28	661  ± 28	1.9  ± 0.1	97  ± 4
Brain stem	389  ± 22	506  ± 18	2.4  ± 0.2	72  ± 4

For level of expression, the numbers represent Gly-current amplitudes (mean ± SEM), evoked by 1 mM glycine in oocytes injected with encephalon, midbrain, and brain stem mRNAs (n = 26, 43, and 18, respectively). The EC₅₀ and IC₅₀ values were derived from the Hill equation.
