The aim of the current study was to investigate the oscillatory neuronal mechanisms underlying two distinct components of hierarchical cognitive control: the level of abstraction of a rule, and the number of rules that must be maintained (set-size). Recent Publications. Distinct oscillatory dynamics underlie different components of hierarchical cognitive control. He researches working memory and frontal lobe function, functional MRI, cognitive neuroscience He is the primary investigator for The D'esposito Lab. The present study used a single-cell whole-brain imaging approach to 1) assess whether abstinence from alcohol in an animal model of alcohol dependence alters the functional architecture of brain activity and modularity, 2) validate our current knowledge of the neurocircuitry of alcohol abstinence, and 3) discover brain regions that may be involved in alcohol use. Emily Goard Jacobs and Michael Jacobs Goard are alumni from the Neuroscience PhD Program entering class of 2004. Building on this previous work, we implemented the DDM as the choice rule in inter-temporal choice (temporal discounting) and risky choice (probability discounting) using hierarchical Bayesian parameter estimation. Further studies are needed to determine whether the changes in coactivation and modularity that are associated with alcohol abstinence are causal features of alcohol dependence or a consequence of excessive drinking and alcohol exposure. Working Groups . The drift diffusion model as the choice rule in inter-temporal and risky choice: A case study in medial orbitofrontal cortex lesion patients and controls. He is also an attending neurologist at the Northern California VA Health Care System and Adjunct Professor of Neurology at UCSF. These results identify brain targets for future research and demonstrate that alcohol use and dependence remodel brain-wide functional architecture to decrease modularity. I use the methods of cognitive neuroscience to address questions about the interactions between perception, attention, memory, and action. I am investigating abnormal cerebral perfusion and what it means for behavior after stroke. We then applied this modeling framework and 1) reproduced our previous results regarding temporal discounting in vmPFC/mOFC patients and 2) showed in a previously unpublished data set on risky choice that vmPFC/mOFC patients exhibit increased risk-taking relative to controls. Relatively intact value processing was also confirmed using DDM mixture models, which revealed that in both groups >98% of trials were better accounted for by a DDM with value modulation than by a null model without value modulation. - The Object Perception Lab at Vanderbilt University has an article which discusses specialized systems vs. expertise Cognitive Control and High-Level Cognition Narrated Videos- Leveraging graph theory to understand the large-scale organization of cognitive control Mark D'Esposito ...

We collected electroencephalography (EEG) data in 31 men and women who performed a hierarchical cognitive control task that varied in levels of abstraction and set-size.

In contrast, vmPFC/mOFC damage abolished neither scaling nor asymptote of the drift rate. Yuan Chang graduated from the lab in 2019. Speaker: Mark D'Esposito, MD Professor of Neuroscience and Psychology, University of California, Berkeley, USA. He's interested in applying data science to the challenges in human neuroscience. Together, these results causally establish dissociable roles for prefrontal theta oscillations and parietal alpha oscillations in the control of internally maintained WM representations. Posterior predictive checks confirmed that this model provided a superior account of the relationship between value and RT. Phase amplitude coupling analysis revealed that delta phase coupled with beta amplitude during conditions with a higher level of abstraction, whereby beta band may potentially represent motor output that was guided by the delta phase. Berkeley Institute for Data Science. I use methods such as structural and functional MRI, perfusion and diffusion MRI, and spectroscopy. Bio: Dr. Mark D’Esposito is Professor of Neuroscience and Psychology, and founding Director of the Henry H. Wheeler, Jr. Mark has challenged me to think fully about questions that I had thought were outside my arena. Here, we used a retrospective-cue WM paradigm to manipulate prioritization and suppression task demands designed to drive theta oscillations in prefrontal cortex and alpha oscillations in parietal cortex, respectively.

Brain-wide functional architecture remodeling by alcohol dependence and abstinence. "Where top-down meets bottom-up: Neural mechanisms of cognitive control" by Mark D'Esposito at CNS on January 23, 2009 Sequential sampling models such as the drift diffusion model (DDM) have a long tradition in research on perceptual decision-making, but mounting evidence suggests that these models can account for response time (RT) distributions that arise during reinforcement learning and value-based decision-making. Dan continued his research career at the University of California, Berkeley working on functional brain imaging in the lab of Mark D’Esposito. Finally, the expression of beta amplitude was coordinated via the phase of delta oscillations, and theta phase coupled with gamma amplitude.

Prioritizing relevant information has been linked to theta frequency neural oscillations in lateral prefrontal cortex and suppressing irrelevant information has been linked to alpha oscillations in occipito-parietal cortex [3,11]. Structuring of the alcohol abstinence network revealed three major brain modules: 1) extended amygdala module, 2) midbrain striatal module, and 3) cortico-hippocampo-thalamic module, reminiscent of the three-stage theory.

Abstract: A fundamental question in cognitive neuroscience is how we are able to flexibly guide our behavior. In 2018, she co-edited the 2nd edition of The Nature of Emotion: Fundamental Questions. Interpretation-Mediated Changes in Neural Activity During Language Comprehension. To causally test the role of these neural oscillations, we applied rhythmic transcranial magnetic stimulation (TMS) in either theta or alpha frequency to prefrontal and parietal regions identified using functional MRI. Alcohol abstinence resulted in the whole-brain reorganization of functional architecture in mice and a pronounced decrease in modularity that was not observed in nondependent moderate drinkers.
