NOTE - this is no longer meeting in D-Lab. 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. 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. He subsequently started as a post-doctoral researcher in the lab of Professor Mark D’Esposito at UC Berkeley, focusing on cognitive control processes that are engaged during learning and memory. At present, I am developing methods to study glucose metabolism, brain thermometry, and the brain-gut axis. As principal physicist in the Brain Imaging Center, I provide support to all neuroscience research on a Siemens 3 T MRI scanner. Senior Research Data Scientist, 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). Yuan Chang graduated from the lab in 2019. Article Causal Contribution of Awake Post-encoding Processes to Episodic Memory Consolidation Arielle Tambini1,2,3,* and Mark D’Esposito1 1Helen Wills Neuroscience Institute and Department of Psychology, University of California, Berkeley, Berkeley, CA 94720, USA 2Department of Neurobiology and Behavior, Center for Neurobiology of Learning and Memory, University of California, Irvine, Irvine, CA 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. Associate Professor in Psychiatry, Harvard Medical School and Associate Biophysicist at McLean Hospital, Belmont MA. He researches working memory and frontal lobe function, functional MRI, cognitive neuroscience He is the primary investigator for The D'esposito Lab. Brian Galla. There he studied how the human brain manages information in working memory and responds to incentives in the form of financial gains and losses. 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. 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. These results suggest that distinct neural oscillatory mechanisms underlie different components of hierarchical cognitive control.Cognitive control allows us to perform immediate actions while maintaining more abstract, overarching goals in mind and to choose between competing actions. Dan continued his research career at the University of California, Berkeley working on functional brain imaging in the lab of Mark D’Esposito. 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. I am investigating abnormal cerebral perfusion and what it means for behavior after stroke. He's interested in applying data science to the challenges in human neuroscience. The Human Intraparietal Sulcus Modulates … At present, I am developing methods to study glucose metabolism, brain thermometry, and the brain-gut axis. Alcohol abuse and alcohol dependence are key factors in the development of alcohol use disorder, which is a pervasive societal problem with substantial economic, medical, and psychiatric consequences. I recently began to investigate markers for brain metabolism using spectroscopy data and the potential changes in stroke patients. Abstract: A fundamental question in cognitive neuroscience is how we are able to flexibly guide our behavior.

Riddle, J, Vogelsang DA, Hwang K, Cellier D, D'Esposito M. Brain-wide functional architecture remodeling by alcohol dependence and abstinence. I use methods such as structural and functional MRI, perfusion and diffusion MRI, and spectroscopy. The first step was to determine a referencing system capable of discriminating between the small chemical shifts of complex, overlapping metabolite patterns, which was achieved with a small molecule sold as a nutritional supplement. 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. Ben is a post-doc in Mark D'Esposito's lab. Magnetic induction has the distinct advantage, compared to scalp electrode methods, of producing much larger electric field amplitudes in the brain for similar electric field amplitudes in the scalp.

Qin (CSU-Sacramento) 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. These results suggest that distinct neural oscillatory mechanisms underlie different components of hierarchical cognitive control. For Justin’s research he addresses the role of neural oscillations in voluntary and automatic cognition. 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. In the years before grad school, I worked in homeless counseling and mental health services. 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 … Hwang, K, Shine JM, Cellier D, D'Esposito M. 2020. 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]. Brain Imaging Center at the UC 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. Gazzaley A, Cooney J, McEvoy K, Knight RT, D’Esposito M.Top-down modulation of visual processing: converging fMRI and ERP evidence, Journal of Cognitive Neuroscience, 17:507-17, 2005.

Brain Imaging Center at the Helen Wills Neuroscience Institute at the University of California, Berkeley. Posterior predictive checks confirmed that this model provided a superior account of the relationship between value and RT. 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. 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.

Georgia Institute of Technology Lab Website: rahnevlab.gatech.edu 130 J.S. Mark has challenged me to think fully about questions that I had thought were outside my arena. In 2016, she was awarded an NIH postdoctoral fellowship to examine the representational properties and causal mechanisms of lateral prefrontal function in emotion with Dr. Mark D'Esposito at the University of California, Berkeley. In 2018, she co-edited the 2nd edition of The Nature of Emotion: Fundamental Questions. Together, these results causally establish dissociable roles for prefrontal theta oscillations and parietal alpha oscillations in the control of internally maintained WM representations. I use the methods of cognitive neuroscience to address questions about the interactions between perception, attention, memory, and action. These results identify brain targets for future research and demonstrate that alcohol use and dependence remodel brain-wide functional architecture to decrease modularity. He combines behavioral experiments, computational modeling and neuroimaging to study how reward and motivation interacts with cognitive processes to shape everyday behavior. I am also interested in using functional MRI to observe non-invasive brain stimulation with magnetic induction in situ, which requires developing new hardware and software that minimizes the interactions between these two methods.

At Wheeler LABS, I aim to foster a collaborative environment that allows basic scientists and clinicians to work on shared goals. We found distinct oscillatory signatures that correspond to two different components of hierarchical control: the level of abstraction of a rule and the number of rules in competition. Ben is a post-doc in Mark D'Esposito's lab. Interpretation-Mediated Changes in Neural Activity During Language Comprehension. Assistant Professor within the Department of Psychiatry and Behavioral Sciences and the Director of the Stanford Brain Stimulation Lab. Analyses of DDM parameters revealed that patients showed substantially increased non-decision times and reduced response caution during risky choice. MOOC: Algorithms - Design and Analysis, Part 1. Justin Riddle is a graduate student at University of California, Berkeley studying cognitive neuroscience under the supervision of Professor Mark D’Esposito. Goard completed his thesis in Yang Dan’s lab on cholinergic neuromodulation of visual perception. 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. E.A. My research interests broadly include the role of attention and memory on category learning as well as the perception of emotional expressions. Causal Evidence for a Role of Theta and Alpha Oscillations in the Control of Working Memory. 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. He is also Director of the Neurorehabilitation Unit at the Northern California VA Health Care System and Adjunct Professor of Neurology at UCSF. My research focus lies in clinical neuroscience, with specific emphasis in stroke. 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. 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. We validated our approach in data from nine patients with focal lesions to the ventromedial prefrontal cortex / medial orbitofrontal cortex (vmPFC/mOFC) and nineteen age- and education-matched controls. An increase in the level of abstraction was associated with delta oscillations, whereas theta oscillations were observed when the number of rules increased. Jacobs completed her thesis in the lab of Mark D’Esposito on the effects of estrogen on dopamine-dependent cognitive processes. 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.
