Figure 4. Cd²⁺ selectively blocked sDBS responses.

A, membrane responses to sDBS before, during bath application of Cd²⁺, and after washout. B, representative trace of single shock-evoked EPSPs before, during bath application of 200 μm Cd²⁺, and after washout. Vertical excursion, indicated by arrow (↓), is stimulus artifact. C, current injection pulses recorded before and during bath application of 200 μm Cd²⁺. Note that the T-type Ca²⁺ channel-dependent LTS remains unchanged in the presence of 200 μm Cd²⁺. All recordings were obtained from the same cell.
