Erratum: Williams et al. “RDX Binds to the GABA_A Receptor–Convulsant Site and Blocks GABA_A Receptor–Mediated Currents in the Amygdala: A Mechanism for RDX-Induced Seizures” [119:357–363 (2011)]

In Figure 2 of the paper by Williams et al. [Environ Health Perspect 119:357–363 (2011)], the units for “Brain RDX concentration” (y-axis) should have been micrograms per gram wet weight (µg/g ww) instead of micrograms per milligram wet weight (µg/mg ww). The corrected Figure 2 is shown below.

The authors regret the error.

Figure 2.

Bioavailability of RDX at the time of RDX-induced seizure onset. (A) Correlation between blood and brain RDX concentrations at seizure onset (CC = 0.81). (B) Correlation between RDX brain concentration and time to seizure onset; the negative correlation (CC = –0.61) indicates that the higher the brain concentration of RDX, the shorter the time to seizure initiation.
