Abstract:
A versatile device for a patch-clamp amplifier is described. This device contains: (i) an acoustic indicator to monitor the input resistance of the patch pipette, which is used in search-mode to indicate the formation of seals; (ii) two pulse generators; and (iii) a staircase generator to produce various pulse and voltage step programs; (iv) a lowpass filter which is used to filter the output of the patch clamp amplifier; and (v) a remote control which is used to control the entire patch clamp experiment. This remote control is used to switch between search-, current clamp-, and voltage clamp-mode, to activate the respective stimulus potential programs, and to control the tape recorder. This electronic device can be easily connected to patch clamp amplifiers.
