Subthalamic nucleus correlates of decision and movement speed.

This dataset is availabel to download from: https://data.mrc.ox.ac.uk/data-set/subthalamic-nucleus-correlates-decision-and-movement-speed This code analyses behavioural data from a group of 13 Parkinson patients and 15 healthy control participants performing a moving dots paradigm with Speed vs. Accuracy instructions. The main behavioural outcomes are reaction times, movement times, peak force and response accuracy (folder 1, used for figure 1 in the published article), as well as computational analysis of behaviour with hierarchical drift diffusion modelling (folder 2, used for figure 2). In patients local field potentials were recorded during the task and corresponding code is stored in folder 3-5 (figure 3). In 10 patients burst deep brain stimulation was applied during a second session. Its effects on behaviour and local field potentials are analysed with code from folder 6 and 7 (figures 4-6). The results have been published in a paper termed ‘Dynamic control of decision and movement speed in the human basal ganglia’ by Herz et al
