Fully-automated in vivo single cell electrophysiology

Abstract

In this work, we report progress in developing a device that allows fully autonomous sequential patch clamp experimentation. The machine works by integrating a storage magazine of pre-filled pipettes that can be accessed, and swapped, by the headstage at the conclusion of each experiment. In operation, following each neuron measurement, the program enters “swap” state where a set of programmed actuator movements take place. First, the headstage translates towards the pipette storage assembly and deposits its used pipette. The storage assembly rotates to index a fresh pipette, its is grasped, and finally, the headstage returns to its previously designated home position in preparation of subsequent experiments.
