This treadmill was developed by engineers at the Janelia Research Campus of the Howard Hughes Medical Institute HHMI. Jon Arnold developed the treadmill and Steve Sawtelle contributed the encoder interface that generates the data. Originally developed for Shengjin Xu (Sternson lab) the treadmill was mostly used by the Lee lab. The treadmill is one of the many innovations of the HHMI Janelia Research Campus that are shared with scientists globally.
