Instantly switch recording modes by using the membrane potential as the trigger. Preset a voltage threshold in current-clamp mode, and MultiClamp 700B automatically switches to voltage-clamp when the membrane potential reaches that voltage level. User-specified delay allows you to perform creative new experiments. Suppress Oscillations Sudden changes in membrane or pipette parameters may result...

I N T R O D U C T I O N T h e voltage c lamp technique has been used by n u m e r o u s investigators to describe the voltageand t i me -dependen t conductances in cardiac tissue. T h e main conclusion f rom these analyses is that the ionic cur ren ts that under l ie the action potent ial in the hear t are m o r e n u m e r o u s and complex than in the classic squid axon (for reviews, see Trau...
