Bio: After receiving a Ph.D. in cognitive neuroscience from the psychology department at UCLA in 2006, Dr. Uddin completed a postdoctoral fellowship at the Child Study Center at NYU. For several years she worked as a faculty member in Psychiatry & Behavioral Science at the Stanford School of Medicine. She joined the psychology department at the University of Miami in 2014. Within a cognitive neuroscience framework, Dr. Uddin’s research combines functional connectivity analyses of resting-state functional magnetic resonance imaging data and structural connectivity analyses of diffusion tensor imaging data to examine the organization of large-scale brain networks supporting executive functions. Her current projects focus on understanding dynamic network interactions underlying cognitive inflexibility in neurodevelopmental disorders such as autism. Dr. Uddin’s work has been published in the Journal of Neuroscience, Cerebral Cortex, JAMA Psychiatry, Biological Psychiatry, PNAS, and Nature Reviews Neuroscience. She was awarded the Young Investigator award by the Organization for Human Brain Mapping in 2017.

Abstract: Executive control processes and flexible behaviors rely on the integrity of, and dynamic interactions between, several core large-scale brain networks. The right insular cortex is a critical component of a salience network that is thought to mediate interactions between brain networks involved in externally oriented and internally oriented processes. I will describe studies examining how brain network dynamics support flexible behaviors in typical and atypical development, presenting evidence suggesting a unique role for the dorsal anterior insular from studies of meta- analytic connectivity modeling, dynamic functional connectivity, and structural connectivity. These findings from adults, typically developing children, and children with autism suggest that structural and functional maturation of insular pathways is a critical component of the process by which human brain networks mature to support complex, flexible cognitive processes throughout the lifespan.

Abstract:

Humans share with animals the ability to process numerical quantities in non-symbolic formats (e.g., collections of objects). Unlike other species, however, over cultural history, humans have developed symbolic representations (such as number words and digits) to represent numerical quantities exactly and abstractly. These symbols and their semantic referents form the foundations for higher-level numerical and mathematical skills. It is commonly assumed that symbols for number acquire their meaning by being mapped onto the pre-existing, phylogenetically ancient system for the approximate representation of non-symbolic number over the course of learning and development. In this talk I will challenge this hypothesis for how numerical symbols acquire their meanings (“the symbol grounding problem”). To do so, I will present a series of behavioral and neuroimaging studies with both children and adults that demonstrate that symbolic and non-symbolic processing of number is dissociated at both the behavioral and brain levels of analysis. I will discuss the implications of these data for theories of the origins of numerical symbol processing and its breakdown in children with mathematical learning disorders, such as Developmental Dyscalculia.

Bio: Daniel Ansari received his PhD from University College London in 2003. Presently, Daniel Ansari is a Professor and Canada Research Chair in Developmental Cognitive Neuroscience in the Department of Psychology and the Brain & Mind Institute at the University of Western Ontario in London, Ontario, where he heads the Numerical Cognition Laboratory (www.numericalcognition.org). Ansari and his team explore the developmental trajectory underlying both the typical and atypical development of numerical and mathematical skills, using both behavioral and neuroimaging methods.

PS: For your entertainment, with the lockdown (in SF), this is my life right now. Perhaps it’s yours, too. 🙂

BIRC’s response to the Coronavirus Outbreak Update #6 3-16-20

Posted on by

With many states and counties advancing into lockdown (SF is stating lockdown of the whole city together with neighboring counties effective tonight – just announced! I believe it will come our way to CT sooner than we think/hope. I hope I am wrong), we have made some adjustments.

We technically remain open until the university announcement, but …

RESEARCH SCANS
We have cancelled all research scans until 4/6 and will continue to discourage scanning unless you can convince us 🙂

CLINICAL SCANS
While UCHC has decided to only cancel elective surgery at this point, and no outpatient services are cancelled, we have agreed to cancel/postpone all clinical scans as well. We will scan the remaining patients if there are critical needs but have suspended all clinical scans at least until 4/6 as well. We are currently not booking any new patients. Thanks for Leo Wolansky (UCHC Radiology Department Chair)’s understanding in the service of protecting our staff.
Hence no disinfection will be done as complete telecommuting has started.

If you have critical needs please contact me.

Stay safe and happy…
Fumiko

A quick update to you all. 

RESEARCH SCANS
We are currently technically open. But we do not have any research scans until the weekend (and they are non-EEG) and will likely close as soon as we get guidance from VPR. They are in discussions and will propose recommendations to the President this afternoon. We are urging the university to stop all non-critical/essential research that does not impact human health ASAP. We should have updates before any further research scans are done.

CLINICAL SCANS
We are in discussions with UCHC Radiology to stop clinical MRI as well as they are non-priority scans.

OTHER ACTIVITIES
We remain open virtually for any consultations or training that can be done remotely. We will suspend in person MRI safety training until further notice. LMK if this impacts your research plans.

Please do not come in to use the conference rooms or data room unless necessary. While we have staff telecommute, we will not be disinfecting the areas as we had originally planned and was doing last week. If you do need to come in to BIRC, please contact me.

Thank you,
Fumiko

Talk: David Badre, Brown University

David Badre, PhD
Brown University

Tuesday, March 3rd from 1:30-3:00 pm in Arjona 307

Abstract:

This talk will describe an on-going line of research in our lab investigating the cognitive and neural systems that support hierarchical cognitive control, or our ability to simultaneously control immediate actions while also holding more abstract, temporally remote goals in mind. Psychologists have long proposed that we have a capacity for hierarchical control, citing its potential contributions to sequential behavior, as well as higher-order planning, reasoning, and abstraction. Despite its importance for cognition, the cognitive and neural mechanisms that support hierarchical control remain unknown. Here I will provide a line of evidence suggesting that this type of complex control partly depends on gating of working memory by cortico-striatal circuits. In this light, I will discuss on-going efforts to develop fMRI methods that can characterize the dimensionality of neural representations in the prefrontal cortex that support complex task control.

Bio:David Badre received his Ph.D. from the Department of Brain and Cognitive Sciences at MIT in 2005. Following a postdoctoral fellowship at the University of California, Berkeley, he joined Brown’s Department of Cognitive, Linguistic, and Psychological Sciences as Assistant Professor in 2008 and was subsequently promoted to Associate Professor in 2014 and then Professor in 2019. He is also an affiliate of the Carney Institute for Brain Science and a trainer in the Neuroscience Graduate Program. His lab at Brown focuses on the cognitive neuroscience of memory and cognitive control with an emphasis on frontal lobe function and organization. Dr. Badre serves on the editorial boards of Psychological Science, Cognitive Science, and Behavioral Neuroscience.  He served as Section Editor covering “Executive Function and Cognitive Control” for Neuropsychologia until 2017. Presently, he serves on the Board of Reviewing Editors for the journal eLife, and he is a standing member of the Cognition and Perception study section of NIH. His research is supported by NINDS and NIMH at the NIH, and through the Office of Naval Research. His work has been recognized by several awards, including an Alfred P. Sloan Foundation Fellowship in Neuroscience, a James S. McDonnell Scholar Award in Understanding Human Cognition, and the Cognitive Neuroscience Society Young Investigator Award. His book on the neuroscience of cognitive control, entitled On Task: How the brain gets things done, will be published in November, 2020 through Princeton University Press.
