This project contains data associated with the paper: Mosher, C.P., Mamelak, A.N., Malekmohammadi, M., Pouratian, N., and Rutishauser, U. (2021). "Distinct roles of dorsal and ventral subthalamic neurons in action selection and cancellation" *Neuron*, in press. Please see the ReadMe file that explains how the data is organized. We used the open source toolbox [OSort][2] for pre-processing and spike-sorting. The open source software[ Lead DBS][3], [FreeSurfer][4], and [3D Slicer ][5]were used to determine anatomical recording locations. Everything else was implemented using MATLAB. This work was made possible by two Brain Initiative grants from the National Institute of Neurological Disorders and Stroke (U01NS103792 to UR and AM, U01NS098961 to NP and UR).
