“…Neuronal activity which convey reward, reward prediction errors, and performance error signals are ubiquitous in the brain and have been described in various brain regions including midbrain, cerebellum, and cortical regions (Amador et al, 2000;Amiez et al, 2006;Chen et al, 2017;Heffley et al, 2018;Heindorf et al, 2018;Isomura et al, 2013;Keller et al, 2012;Kostadinov et al, 2019;Krigolson and Holroyd, 2007;Laubach et al, 2000;Mathis et al, 2017;Matsumoto et al, 2007;Olson, 2004, 2005;Sajad et al, 2019;Schall et al, 2002;Schultz, 2000;Shadmehr and Krakauer, 2008;Stuphorn et al, 2000;Teichert et al, 2014;Wallis and Kennerley, 2010;Watabe-Uchida et al, 2017;Wickens et al, 2003). Such signals were shown to serve in error-based and reinforcement learning behavioral paradigms (Glascher et al, 2010;Mathis et al, 2017;Shadmehr and Krakauer, 2008;Wolpert et al, 2011) and such combined signals can enhance adaptation (Galea et al, 2015;Nikooyan and Ahmed, 2015).…”
