She received a PhD in Psychology (Cognitive Neuroscience) from the University of Illinois at Urbana-Champaign under the mentorship of Arthur Kramer, Monica Fabiani, and … These results suggest that distinct neural oscillatory mechanisms underlie different components of hierarchical cognitive control. Oscillatory amplitude correlated with behavioral performance in the task. 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. Schedule: Mondays, 3:00pm - 5:00pm. These results identify brain targets for future research and demonstrate that alcohol use and dependence remodel brain-wide functional architecture to decrease modularity. His lab has developed and implemented a wide range of approaches and methods to study brain function including functional MRI, transcranial magnetic stimulation, electrocorticography, pharmacological interventions and behavioral studies of patients with neurological disorders. Location: D-Lab Convening Room. Causal Evidence for a Role of Theta and Alpha Oscillations in the Control of Working Memory. 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1) reproduced our previous results regarding temporal discounting in vmPFC/mOFC patients and 2) showed in a previously unpublished data set on risky choice that vmPFC/mOFC patients exhibit increased risk-taking relative to controls. I’ve learned so much from every lab member, and I’m grateful for everyone who has made the lab such an enjoyable place to work.

Sasha Gibbs, a graduate student in Mark D’Esposito’s lab, and HWNI physicist Charlene Tan show off the fMRI machine at the Wheeler Brain Imaging Center. There he studied how the human brain manages information in working memory and responds to incentives in the form of financial gains and losses. Previous research has suggested that neuronal oscillations at different frequency bands are associated with top-down cognitive control, however, whether distinct neural oscillations have similar or different functions for cognitive control is not well understood. Read more about Ben Bowles; When & Where. I completed my Ph.D. with Tobias Egner at Duke, and postdoctoral research with Mark D’Esposito at UC Berkeley. 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. Many hub brain regions that control this network were identified, including several that have been previously overlooked in alcohol research. Senior Research Data Scientist,
My research aims to provide insights into brain metabolism in healthy aging using advanced 1 H MR spectroscopy (MRS) methods. 2 and genes in the brain, but at the end of the day you still don’t know how the brain works —how we see, how we perceive, ” he says. I am investigating abnormal cerebral perfusion and what it means for behavior after stroke. Yuan Chang graduated from the lab in 2019. 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. My main interest is the non-invasive stimulation of the brain by magnetic induction.

In contrast, vmPFC/mOFC damage abolished neither scaling nor asymptote of the drift rate. In 2018, she co-edited the 2nd edition of The Nature of Emotion: Fundamental Questions. Our project-oriented (ad hoc) teams are driven to provide new tools in medicine or to improve existing tools, and to deploy them in the most efficient way possible, whether through blogs, peer-reviewed publications, patents or startup companies. Our results highlight that novel insights can be gained from applying sequential sampling models in studies of inter-temporal and risky decision-making in cognitive neuroscience. The effect of rhythmic TMS on WM performance was dependent on whether the TMS frequency matched or mismatched the expected underlying task-driven oscillations of the targeted region. 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. Marc Ettlinger. I am collaborating with members of Mark D’Esposito’s lab on the analysis of several different types of resting state data, and in the process we are developing new software tools that will be made available as part of the open-source NiPy project.

Mark D’Esposito, MD Professor of Neuroscience and Psychology, and Director of the Henry H. Wheeler, Jr. Distinct oscillatory dynamics underlie different components of hierarchical cognitive control. Although our understanding of the neurocircuitry that underlies alcohol use has improved, novel brain regions that are involved in alcohol use and novel biomarkers of alcohol use need to be identified. Emily Goard Jacobs and Michael Jacobs Goard are alumni from the Neuroscience PhD Program entering class of 2004. Together, these results causally establish dissociable roles for prefrontal theta oscillations and parietal alpha oscillations in the control of internally maintained WM representations. Mark has challenged me to think fully about questions that I had thought were outside my arena. Director Mark D'Esposito, MD Professor of Neuroscience & Psychology Dr. Lana Kaiser, PhD. ... Mark D’Esposito. Analyses of DDM parameters revealed that patients showed substantially increased non-decision times and reduced response caution during risky choice. Particular thanks to my officemates over the years (Courtney Gallen, Adam I am interested in using magnetic resonance and other non-invasive methods to study physiology and biochemistry of the brain. Results from time-frequency analysis in frontal electrodes showed an increase in theta amplitude for increased set-size, whereas an increase in delta was associated with increased abstraction. Both theta and delta amplitude correlated with behavioral performance in the tasks but in an opposite manner: theta correlated with response time slowing when the number of rules increased whereas delta correlated with response time when rules became more abstract. Associate Research Professor. 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.

Functional MRI in the targeted regions predicted subsequent TMS effects across subjects supporting a model by which theta oscillations are excitatory to neural activity, and alpha oscillations are inhibitory. I would like to also thank my advisor Mark D’Esposito for taking me into his lab so completely even though I did not begin graduate school working with him. 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. Dr. D’Esposito’s lab investigates the neurophysiological and neurochemical mechanisms underlying cognition, how the brain recovers from injury and potential treatments for the injured brain. Jacobs completed her thesis in the lab of Mark D’Esposito on the effects of estrogen on dopamine-dependent cognitive processes. Visiting Researcher, Department of Psychology, UC Berkeley and Adjunct Professor, Department of Neurology, UC Davis.

Brain Imaging Center (2000-2020) at the Helen Wills Neuroscience Institute at the University of California, Berkeley. A time varying magnetic field, produced by a coil placed on the head, induces an electric field within the brain which couples to neurons and potentially affects their short and long term behavior. Working memory (WM) relies on the prioritization of relevant information and suppression of irrelevant information [1, 2]. 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. My research interests broadly include the role of attention and memory on category learning as well as the perception of emotional expressions. In the years before grad school, I worked in homeless counseling and mental health services. In the lab, I am responsible for fMRI task design, data collection and analysis for the Decision-Making in Alzheimer’s and Related Dementias and the Online Studies of Decision-Making in Healthy Aging projects.
