Research output: Contribution to journalArticle


A stepper motor controlled microdrive designed for isolation of single neurons in unanesthetized animals is reported here. The microdrive permits vertical microelectrode movements in 1.07 μ steps, and multiple penetrations of the recording area. The microdrive also permits the recording electrode to be left in situ between recording sessions and its use is consistent with sterile technique.
