Cl⁻_in in spinal motoneurons and interneurons increases with longer durations of GABA_AR block.

<p>Cl⁻_in for motoneurons and interneurons in control cords, and cords treated with gabazine for 12, 24, or 48 hours or treated with bicuculline for 48 hours. Cell averages for motoneuron and interneuron Cl⁻_in (mM) for all cells in a given condition, and n represents the number of cells. Cord averages for motoneurons represents the average of cord values in a given condition and n represents the number of cords. Cord averages for interneurons are not included as they were highly variable due to the variability of interneuron numbers per cord. Interneuron cord n's are: control = 13, 12 h gabazine = 7, 24 h gabazine = 6, and 48 h gabazine = 5.
