Figure 7. Membrane potential oscillations persist after VGCC blockade.

A Membrane potential oscillations were induced in a ventral horn neuron in whole-cell current clamp by application of NMDA (50 µM) and TTX (1 µM), buffered with OGB1 (25 µM). Repetitive oscillations (control, black) persisted in the presence of Cd²⁺ (teal; 25 µM) with a small reduction in plateau duration, partially recovering upon washout (grey). B Summary of Cd²⁺ effects on oscillation plateau duration, frequency, and trough period duration.
