• How distinct functional insular subdivisions mediate interacting neurocognitive systems

  Cerebral Cortex · 2022-04-14 · 47 citations

  articleOpen access

  Recent neurocognitive models propose that the insula serves as a hub of interoceptive awareness system, modulating 2 interplaying neurocognitive systems: The posterior insula (PI) receives and integrates various interoceptive signals; these signals are then transmitted to the anterior insula for processing higher-order representations into awareness, where the dorsal anterior insula (dAI) modulates the prefrontal self-control system and the ventral anterior insula (vAI) modulates the amygdala (A…

• Auricular transcutaneous vagus nerve stimulation modulates the heart-evoked potential

  Brain stimulation · 2021-12-18 · 46 citations

  articleOpen access

  BACKGROUND: There is active interest in biomarker discovery for transcutaneous auricular vagus nerve stimulation (taVNS). However, greater understanding of the neurobiological mechanisms is needed to identify candidate markers. Accumulating evidence suggests that taVNS influences activity in solitary and parabrachial nuclei, the primary brainstem relays for the transmission of visceral sensory afferents to the insula. The insula mediates interoception, which concerns the representation and regul…

• The role of the insula in internet gaming disorder

  Addiction Biology · 2020-03-08 · 45 citations

  articleOpen accessSenior author

  Internet gaming disorder (IGD) is a concerning issue that requires further research. Here, we seek to examine its neural etiology with an emphasis on the role of the insula. To do so, we relied on the tripartite neurocognitive model of addictive behaviors as applied to IGD. We hypothesized that (a) video game cues will elicit stronger reward system activation and weaker prefrontal activation in gamers vs controls, (b) the IGD scores of gamers will be positively associated with activation of the…

• Neurobiology of Substance Addictions

  Cambridge University Press eBooks · 2020-08-31 · 44 citations

  book-chapterSenior author

  Earlier neurobiological models of substance addictions proposed that addiction is the product of an imbalance between two separate, but interacting, neural systems: (1) an impulsive and amygdala-striatum dependent system that promotes automatic and habitual behaviors, and (2) a "reflective" prefrontal cortex dependent system for decision-making, forecasting the future consequences of a behavior, and inhibitory control. These impulsive and reflective systems are analogous to Daniel Kahneman's mod…

• A Triple-System Neural Model of Maladaptive Consumption

  Journal of the Association for Consumer Research · 2021-03-18 · 28 citations

  articleOpen accessSenior author

  Consumption is a rewarding experience that results in dopamine processing in the brain. Repeated and frequent rewarding consumption experiences can sensitize some consumers to “want” more consumption. Unfortunately, some cannot resist such temptations and fail to override their impulsions, which results in maladaptive consumption. Here, we extend the neuro-marketing literature on the neural basis of normal consumption by describing a triple neural model of maladaptive consumption. The systems in…
