Cortico-Basal Ganglia Reward Network: Microcircuitry (2009, unknown): “Dopamine and particularly its projections to the ventral striatal complex are strongly implicated in the facilitation of approach behaviors and incentive learning (Horvitz, 2000; Wise, 2004; Fields et al, 2007; Ikemoto, 2007; Schultz, 2007; Redgrave et al, 2008).”
Decision theory, reinforcement learning, and the brain (2008, background): “…et al., 2002; Balleine et al., 2007; Daw and Doya, 2006; Haruno et al., 2004) in a way that ties together the at least equally extensive data on the psychology of instrumental choice with these neural data, has extensive, though not universal, support (eg Berridge, 2007; Redgrave et al., 2007).”
From modulated Hebbian plasticity to simple behavior learning through noise and weight saturation (2012, background): “, 2005; Hasselmo, 2006)) is still debated, in particular regarding the role of dopamine in reward learning (Pennartz, 1996, 1997; Berridge and Robinson, 1998; Montague et al., 2004; Schultz, 2006; Redgrave et al., 2008).”
Burst timing-dependent plasticity of NMDA receptor-mediated transmission in midbrain dopamine neurons: A putative cellular substrate for reward learning (2009, unknown): “necessarily selective to reward, but instead sensitive to “biological salience” in that important, significant, surprising, or novel stimuli activate DA neurons, not just rewards and reward contingencies (Redgrave and Gurney, 2006; Redgrave et al., 2008; Redgrave et al., 1999; Ungless, 2004).”
Goal-directed and habitual control in the basal ganglia: implications for Parkinson's disease (2010, background): “, whereas sensory-evoked phasic activity provides 'teaching signals' for instrumental learning”
Intrinsically Motivated Learning in Natural and Artificial Systems (2013, background): “But there are several known phenomena that do not fit the reward prediction error hypothesis of phasic dopamine, which are not discussed here as they are reviewed at length in Redgrave et al. (2012). The most important point for the present discussion is the fact that phasic dopamine is triggered no”
Superior Colliculus and Visual Spatial Attention (2013, background): “However, SNpc neurons also respond to unexpected and salient sensory events (Redgrave et al. 2008, Schultz & Romo 1990), which could be driven at least in part by inputs from the SC and linked to shifts of spatial attention.”
Evolutionary and Computational Advantages of Neuromodulated Plasticity (2008, background): “This finding brought the focus on the role of unexpectedness as a driving mechanism for learning in changing environments (Brown et al., 1999; Ranganath and Rainer, 2003; Dayan and Yu, 2006; Redgrave et al., 2008).”
Striatal dopamine release is triggered by synchronized activity in cholinergic interneurons. (2012, unknown): “…and subsequent DA release encode motivational value and/or salience (Bromberg-Martin et al., 2010; Jin and Costa, 2010; Phillips et al., 2003; Redgrave et al., 2008; Schultz, 2010; Tsai et al., 2009) and regulate long-term changes in striatal synaptic plasticity (Owesson-White et al., 2008;…”
The Social Salience Hypothesis of Oxytocin. (2016, unknown): “The detection of salient stimuli is centrally regulated by the dopaminergic system (86, 87) and is characterized by a sharp increase (phasic) in dopaminergic activity, 70-100ms post the presentation of the stimulus, and occurs before an orienting gaze-shift, which has a latency of 150-200ms indicati”
