My research focus lies in clinical neuroscience, with specific emphasis in stroke. Associate Research Professor. I’m a postdoctoral fellow in Dr. Mark D’Esposito’s lab at the University of California, Berkeley. 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. My main interest is the non-invasive stimulation of the brain by magnetic induction. These results identify brain targets for future research and demonstrate that alcohol use and dependence remodel brain-wide functional architecture to decrease modularity. Particular thanks to my officemates over the years (Courtney Gallen, Adam 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.

Wheeler, Jr. He's interested in applying data science to the challenges in human neuroscience. 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 completed my Ph.D. with Tobias Egner at Duke, and postdoctoral research with Mark D’Esposito at UC Berkeley. 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. For Justin’s research he addresses the role of neural oscillations in voluntary and automatic cognition. 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. Description. Abstract: A fundamental question in cognitive neuroscience is how we are able to flexibly guide our behavior. Dan continued his research career at the University of California, Berkeley working on functional brain imaging in the lab of Mark D’Esposito. Registration: available now on Eventbrite Livestreaming via Vimeo: Vimeo Abstract: What type of system is the brain?The brain is widely assumed to be one of many modular systems in nature, which are thought to be computational tractable and favored by evolution. Ben is a post-doc in Mark D'Esposito's lab. Associate Professor in Psychiatry, Harvard Medical School and Associate Biophysicist at McLean Hospital, Belmont MA. At Wheeler LABS, I aim to foster a collaborative environment that allows basic scientists and clinicians to work on shared goals. In contrast, vmPFC/mOFC damage abolished neither scaling nor asymptote of the drift rate. Lab Manager Hello! 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. The D'Esposito Lab is a cognitive neuroscience research laboratory within theHelen Wills Neuroscience Institute and the Department of Psychology. Working memory (WM) relies on the prioritization of relevant information and suppression of irrelevant information [1, 2]. 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. 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. Analyses of DDM parameters revealed that patients showed substantially increased non-decision times and reduced response caution during risky choice. 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. He has encouraged me to see no obstacle and to learn whatever technique is appropriate At present, I am developing methods to study glucose metabolism, brain thermometry, and the brain-gut axis.

Director Mark D'Esposito, MD Professor of Neuroscience & Psychology Dr. Lana Kaiser, PhD. Small. The D'Esposito Lab is a cognitive neuroscience research laboratory within the. Assistant Professor within the Department of Psychiatry and Behavioral Sciences and the Director of the Stanford Brain Stimulation Lab. 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 2018, she co-edited the 2nd edition of The Nature of Emotion: Fundamental Questions. constant encouragement of the D’Esposito lab and my graduate advisor, Mark D’Esposito.

Riddle, J, Vogelsang DA, Hwang K, Cellier D, D'Esposito M. Brain-wide functional architecture remodeling by alcohol dependence and abstinence. E.A. Drawing on his training in Neurology, Neuroscience and Psychology, his research focuses on investigating the neural bases of high-level cognitive processes such as working memory and cognitive control, achieved through several different experimental approaches and methodologies. 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. He researches working memory and frontal lobe function, functional MRI, cognitive neuroscience He is the primary investigator for The D'esposito Lab. Finally, the expression of beta amplitude was coordinated via the phase of delta oscillations, and theta phase coupled with gamma amplitude. Goard completed his thesis in Yang Dan’s lab on cholinergic neuromodulation of visual perception. 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. I use the methods of cognitive neuroscience to address questions about the interactions between perception, attention, memory, and action. 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. Causal Evidence for a Role of Theta and Alpha Oscillations in the Control of Working Memory. Hierarchical cognitive control enables us to execute actions guided by abstract goals. Working Groups . Advisors: Carla L. Hudson Kam & Mark D’Esposito Dissertation: The sensitive period for language acquisition: The role of age related differences in cognitive and neural function B.A. These results suggest that distinct neural oscillatory mechanisms underlie different components of hierarchical cognitive control. 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. 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.

I am also investigating the different roles of functional and structural disconnections that come with different lesions and their impact on brain network reorganization. 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. He combines behavioral experiments, computational modeling and neuroimaging to study how reward and motivation interacts with cognitive processes to shape everyday behavior. Baniqued completed an NIH post-doctoral fellowship at the University of California, Berkeley, in the lab of Mark D’Esposito. Email: bbowles2@berkeley.edu. Collectively, I aim to use these neural markers to predict recovery and rehabilitation. Distinct oscillatory dynamics underlie different components of hierarchical cognitive control. "Where top-down meets bottom-up: Neural mechanisms of cognitive control" by Mark D'Esposito at CNS on January 23, 2009 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.
