Updating P300: an integrative theory of P3a and P3b. (2007, unknown): “…to frontal focal attention and working memory mediated by dopaminergic activity, and that P3b is related to temporal–parietal activity where dense norepinephrine inputs are found (cf. Braver and Cohen, 2002; Nieuwenhuis et al., 2005; Pineda, 1995; Pineda et al., 1989; Polich and Criado, 2006).”
Explaining the many varieties of working memory variation: Dual mechanisms of cognitive control. (2007, background): “A general theoretical model of working memory In previous work, we have developed an overarching theoretical model of working memory that attempts to specify critical WM components in terms of underlying neurobiologically-based computational mechanisms (Botvinick, Braver, Barch, Carter, & Cohen, 200”
When Things Are Better or Worse than Expected: The Medial Frontal Cortex and the Allocation of Processing Resources (2006, background): “…TX, 2Baylor College of Medicine, Houston, TX D 2006 Massachusetts Institute of Technology Journal of Cognitive Neuroscience 18:7, pp. 1112–1119 relevant information gains access to limited-capacity control systems in the prefrontal cortex (PFC) (Cohen, Braver, & Brown, 2002; Braver & Cohen, 2000).”
Decision making, the P3, and the locus coeruleus-norepinephrine system. (2005, background): “…proposed that this effect is mediated by noradrenergic modulation of sensitivity to distracting stimuli, whereas dopamine is primarily involved in the working memory function of prefrontal cortex (e.g., Arnsten, 1997; Braver & Cohen, 2000; Clark et al., 1987, 1989; Cohen & ServanSchreiber, 1992).”
Cognitive Control Predicts Use of Model-based Reinforcement Learning (2014, methodology): “Next, to ensure that the control measures yielded by the DPX task reflect understanding of the task instructions and engagement with the task, we excluded the data of 13 participants who exhibited a d 0 of less than 2.5 in classifying target versus nontarget responses.”
Making Working Memory Work: A Computational Model of Learning in the Prefrontal Cortex and Basal Ganglia (2006, background): “…other when viewed in terms of standard neural processing mechanisms, and thus motivate the need for a dynamic gating mechanism to switch between these modes of operation (see Figure 2; Cohen et al., 1996; Braver & Cohen, 2000; O’Reilly et al., 1999; O’Reilly & Munakata, 2000; Frank et al., 2001).”
Banishing the homunculus: making working memory work. (2006, background): “This motivates the obvious need for a dynamic gating mechanism to switch between these two modes of operation (Cohen et al., 1996; Braver & Cohen, 2000; O'Reilly et al., 1999; O'Reilly & Munakata, 2000).”
Event perception: a mind-brain perspective. (2007, background): “…Miller and Cohen (2001) suggested that updating of PFC representations could be gated by phasic dopamine signals from midbrain dopamine neurons (Braver & Cohen, 2000), triggered by encountering unexpected rewards; other models address the possibility that unexpected lack of reward may also…”
Towards an executive without a homunculus: computational models of the prefrontal cortex/basal ganglia system (2007, methodology): “The AX-CPT is a standard working memory task that has been extensively studied in humans (Cohen et al. 1997; Braver et al. 1999, submitted; Braver & Cohen 2000; Frank & O'Reilly 2006).”
The expected value of control: An integrative theory of anterior cingulate cortex function (2013, unknown): “…associated structures (e.g., basal ganglia andbrainstemdopaminergic nuclei) have been proposed to implement the regulative component of the model (Braver and Cohen, 2000; Cohen and Servan-Schreiber, 1992; Frank et al., 2001; Miller and Cohen, 2001), while dACC has been proposed to implement the…”
Performance Monitoring in the Anterior Cingulate is Not All Error Related: Expectancy Deviation and the Representation of Action-Outcome Associations (2007, background): “At first glance, the expectancy-deviation hypothesis seems incompatible with the results of previous studies that used guessing and gambling tasks to investigate how expectation of feedback modulates the amplitude of the FRN. Negative feedback elicited larger FRNs compared to positive feedback when ”
