Selective attention and the visual representation of object attributes in the ventrolateral prefrontal cortex and anterior cingulate cortex of the rhesus monkey
… 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 multi-factor ANOVAs. …

Resting-State Functional Brain Networks in Bipolar Spectrum Disorder: A Graph Theoretical Investigation
… control region (dorsolateral prefrontal cortex), but increased connectivity of a brain region involved in the detection and processing of reward (bilateral orbitofrontal cortex), among participants at high risk for BSD. Participants with BSD showed increased inter-module connectivity of …

Evaluating Changes in Error-Monitoring Electrocortcial Responses as an Outcome of Attention Bias Modification Training
… that both processes recruit – in particular, the anterior cingulate cortex (ACC). The results demonstrate no reduction in anxiety following ABM, but reductions in attention bias in both the ABM and control groups. There were also no significant relationships between ERN and ABM outcome, suggesting …

Substrates of social functioning in individuals with VCFS
… 6 controls. Controls were identically matched according to age and gender. It was hypothesized that after covarying for total brain volume, VCFS patients would exhibit larger amygdala and insula volumes and smaller prefrontal cortex (PFC), orbitofrontal cortex (OFC), dorsolateral prefrontal …

Understanding Autonomic Control via Human Deep Brain Stimulation
… control in the brain, such as the role of the anterior cingulate cortex (ACC) in the cardiovascular response to intermittent exercise. Besides advancing understanding of the regulation of these autonomic processes, this work has also directly resulted in first in-human clinical trials of DBS …

Neural Correlates of Adolescent Mindfulness, Working Memory, and Internalizing Symptoms
… 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 between attention and …

Overactive conflict-monitoring and separation-distress : cognitive and affective components of obsessive-compulsive disorder ?
… highly correlated both with hyperactivity in the anterior cingulate cortex (ACC) and with symptom severity in OCD- and therefore that overactive conflict-monitoring can be conceptualized as a possible mechanism of the disorder - it was hypothesized that hyperactivity of the …

Behavioral and Functional Brain Correlates of Developmental Coordination Disorder: A Case-Control Study
… robust activations (p < 0.01) in the left motor cortex and left inferior parietal lobe while performing the tracking task. These results imply that the DCD subject relied heavily on visual (instead of tactile) feedback when performing the visuo-motor task as opposed to the control subject who …

Electrophysiological correlates of performance monitoring in middle and late adolescence
… seems to rely on networks including the anterior cingulate cortex (ACC) and phasic changes in dopamine activity. Activity (and presumably functional maturation) of the ACC may be indirectly measured using the error-related negativity (ERN), an event-related potential (ERP) component that …

Neurofunctional Characterization of the At-Risk Mental State for Psychosis
… tegmental area (VTA) and dorsolateral prefrontal cortex (DLPFC) responses to reward anticipation. In the hippocampus-dependent learning task, at-risk individuals showed deficits in hippocampus-dependent memory, decreased VTA engagement, and increased DLPFC activation during learning of …

Decoding observational learning : a circuit level analysis of the social brain
… a number of questions about the role of the anterior cingulate cortex (ACC) and the basolateral amygdala (BLA) in observational fear learning. We show that both the ACC and the BLA contain neurons that show conditioned responses to the cue and are therefore neural correlates of observational …

Separating Within-trial Activities in the Stop Signal Task Using fMRI
… dopamine neurons (dorsal striatum and ventral anterior cingulate cortex (ACC)), followed by deactivations during post-error adjustment in structures that modulate the ascending dopamine response (ventral striatum and caudal orbitofrontal cortex), which encode error magnitude. The third study …

Distinguishing Medial Temporal Lobe and Prefrontal Cortex Contributions to Approach-Avoidance Conflict in Healthy Controls and Generalized Anxiety Disorder: Insights from Functional Magnetic Resonance Imaging and the Hierarchical Drift Diffusion Model
… temporal lobe (MTL), striatum, and prefrontal cortex (PFC). This work, however, is limited in two respects. (1) Human models employing functional Magnetic Resonance Imaging (fMRI) have historically relied on analyses that fail to disentangle how neural activity relates to decision-making …

Social defeat and oxytocin regulation of social avoidance and stress-related signaling proteins
… binding was progressively reduced in the nucleus accumbens (NAc), basal lateral amygdala (BLA), and anterior cingulate cortex (ACC) of defeated female prairie voles over an eight-week period, suggesting a regulatory role of this neuropeptide in the etiology of SAD. Oxytocin stimulation of its …

An fMRI and TMS investigation of response, semantic, and task conflict in the Stroop task.
… these different cognitive processes. The anterior cingulate cortex (ACC) and dorsolateral prefrontal cortex (DLPFC) are two regions thought to be central to the circuitry of attentional control, however the precise role that each plays is still widely debated. The present thesis attempts …

Neural Mechanisms Involved in Emotion /Attention Interactions
… involved remain unclear. Dorsolateral prefrontal cortex (DLPFC), amygdala, dorsal (dACC), and rostral (rACC) anterior cingulate cortex (ACC) have been shown to play a critical role in the interaction of emotion and attention processes. The present project proposes a model of brain connectivity …

Role of prefrontal cortex and cholinergic modulation in attentional performance in rats
… thesis investigates the role of the prefrontal cortex and cholinergic modulation in attentional performance, and to a lesser extent, inhibitory response control, in rats. A greater understanding of these functions is important for the effective treatment of attentional and impulsive control …

Behavioral Strategies and Neural Mechanisms of Dynamic Foraging
… in blocks of trials. These states can be accurately decoded as sub-regimes of model-free or inference-based behavior. Widefield imaging and unsupervised analysis of the cortical activity during the behavior revealed distinct cortical activation modes corresponding to the frontal, motor, …

Sequential Transcriptional Gates in The Thalamo-Cortical Circuit Coordinate Memory Consolidation

Multiplexed representations of uncertainty by mouse pulvinar-prefrontal projections during goal-directed behaviors
