A modeling framework for adaptive lifelong learning with transfer and savings through gating in the prefrontal cortex (2020, background): “Some studies have provided evidence for such a functional architecture in the brain [27], and prefrontal cortical areas in particular [28],[29],[30].”
Alleviating catastrophic forgetting using context-dependent gating and synaptic stabilization (2018, background): “In contrast, context-dependent signals in the brain, likely originating from areas such as the prefrontal cortex, project to various cortical areas and allow neural circuits to process incoming information in a task-dependent manner (Engel et al., 2001; Johnston et al., 2007).”
Behavioral shifts and action valuation in the anterior cingulate cortex. (2008, unknown): “Several authors have proposed that ACC might form part of a dedicated network involve in task maintenance or task control that is in the ensemble of processes involved in regulating task performance (Braver et al., 2003; Dosenbach et al., 2006 ; Johnston et al., 2007; Roelofs et al., 2006).”
The expected value of control: An integrative theory of anterior cingulate cortex function (2013, unknown): “Interestingly, when rule-selective activity reemerged prior to a correct trial following an error, the selectivity was seen earlier than on correct trials that followed a previous correct one (see also Johnston et al., 2007).”
Cortical Information Flow During Flexible Sensorimotor Decisions (2015, unknown): “Neuronal activity encodes task rules in prefrontal (6, 8, 14, 15), parietal (2), and visual (16) cortices.”
Large-Scale Brain Networks in Cognition: Emerging Principles (2010, methodology): “Our model further suggests that when the ACC is dysfunctional (Fellows and Farah, 2005; Baird et al., 2006), the AI is well positioned to trigger alternative cognitive control signals via other lateral cortical regions such as the VLPFC and the DLPFC (Johnston et al., 2007).”
Saliency, switching, attention and control: a network model of insula function (2010, unknown): “…in a variety of monitoring, decision-making, and cognitive control processes (Cole and Schneider 2007; Crottaz-Herbette and Menon 2006; Dosenbach et al. 2008; Eichele et al. 2008; Johnston et al. 2007; Posner and Rothbart 2007), but the AI has not been a particular focus of most of these studies.”
