The role of ventrolateral prefrontal cortex in performance of spatial self-ordered response sequences in the marmoset
The ventrolateral prefrontal cortex (vlPFC) in primates plays an important role in cognitive control and working memory, but as argued in the Introduction its contribution to those aspects of goal-directed behaviour such as planning and executing spatial response sequences requires further …

Understanding the Role of the Ventrolateral Prefrontal Cortex in Emotional Memory using Transcranial Direct Current Stimulation and Transcranial Magnetic Stimulation
… stimuli. Recent evidence suggests that the ventrolateral prefrontal cortex (VLPFC) has multiple roles in the enhancing effects of emotion on memory through top-down/controlled processes, including 1) coping with negative distraction and 2) elaborative encoding of negative information. …

Selective attention and the visual representation of object attributes in the ventrolateral prefrontal cortex and anterior cingulate cortex of the rhesus monkey
… extracellular recordings were made in the ventrolateral prefrontal cortex (VLPFC) and anterior cingulate cortex (ACC) while the monkey performed the task. Neuronal selectivity for matching rule, object attributes, attribute relevance, response choice, and congruency were assessed using …

Investigating Neuronal Cell Classes and their Role in Cognition
… intraparietal area (LIP), the dorsolateral and ventrolateral prefrontal cortex (PFC) and the extrastriate visual area (V4). While the number of cell classes found across areas differed, there were several classes across areas that appeared to be correlates. Classes in each area also showed …

Maternal antecedents to adolescent girls’ neural regulation of emotion
… more positive (i.e., ineffective) amygdala-right ventrolateral prefrontal cortex (rVLPFC) connectivity. Further, path analysis revealed that there was an indirect effect of maternal anxious attachment on adolescent functional connectivity through maternal emotional awareness. These results suggest …

Controlling memory and resolving interference : prefrontal contributions to flexible behavior
… and (2) the consistent finding of activation in ventrolateral prefrontal cortex (VLPFC) during task switching. These observations motivate the hypothesis that left VLPFC may resolve proactive interference arising from long-term memory during a task switch. Chapters 2 and 3 describe three fMRI …

Neural Correlates of Adolescent Mindfulness, Working Memory, and Internalizing Symptoms
… correction was computed in the dorsolateral and ventrolateral prefrontal cortex (dlPFC, vlPFC) and the anterior cingulate cortex (ACC). Controlling for neuroticism, sex, and mindfulness experience, higher adolescent dispositional mindfulness, including higher self-acceptance and the interaction …

The contribution of childhood negative emotionality and cognitive control to anxiety-linked neural dysregulation of emotion in adolescence
… connectivity between the amygdala and right ventrolateral prefrontal cortex (rVLPFC) during emotion regulation and found that NE predicted a less mature pattern of positive amygdala-rVLPFC connectivity while CC predicted a more mature pattern of negative amygdala-rVLPFC connectivity. …

The Association Between Exposure to Poverty and Anxiety in Middle Childhood: Examination of the Modulating Roles of Coping, Responses to Stress, and Threat Bias Neural Activity
… time spent in poverty since birth was related to ventrolateral prefrontal cortex activation in response to an emotional threat-bias task. These findings support the differential impact of stress responses and neural correlates of threat bias on the relationship between childhood exposure to …

Pharmacological fMRI on the effects of Fluoxetine on functions of Working Memory, Impulsiveness and Cognitive Flexibility in boys with Attention Deficit Hyperactivity Disorder and boys with Autism Spectrum Disorder
… shared underactivation in right dorsolateral prefrontal cortex (DLPFC). ASD boys showed disorder-specific deactivation of posterior cingulate (PCC). Under Fluoxetine, DLPFC underactivation in ASD was significantly normalised and PCC deactivation was increased in ADHD, relative to controls. …

Contributions of Signal-detection Mechanisms and Semantic Memory Representations to Famous Name Recognition
… gyrus and an inferior aspect of the left ventrolateral prefrontal cortex. Overall, my thesis advances our knowledge of how feelings of familiarity for famous names relate to underlying semantic representations about them.

The Neural Computation of Trust and Reputation
… connectivity between the caudate nucleus and ventrolateral prefrontal cortex, which was anti-correlated with retaliation rates. Moreover, in addition to affecting learning mechanisms, violation of trust clearly influenced emotional arousal and increased subsequent recognition of partners who …

Driver Response to Dynamic Message Sign Safety Campaign Messages
… that younger drivers had more activation in the ventrolateral prefrontal cortex, an area known for semantics and word processing, which might indicate more cognitive attention to these types of messages. This study provides a unique application of using neuroimaging techniques to understand …

A comparative analysis of musical ability and performance on mathematical exams determined by brain activity and scoring
… processes that are largely associated with the prefrontal cortex and include working memory, attention shifting, decision making, and cognitive flexibility. The aim of this study is to determine the cognitions w/ music which music enhances executive functions, how this translates to performance …

Domain-general control mechanisms underlying stopping of thought and action

The impact of emotional distraction on cognition: from basic brain responses to large-scale network interactions
… hemispheric dissociation emerged in the lateral prefrontal cortex (PFC) related to coping with emotional distraction, with women showing a positive correlation with WM performance in left ventral PFC, and men showing similar effects in the right dorsal PFC. Study three investigated the impact and …
