The goal of our research program is to better understand how large-scale networks operate during cognition. We use the visual attention network as a model network. Our work is guided by the questions how large-scale networks set up efficient communication and which neural code is used in different network nodes to drive behavior. We study these issues in two primate brain models, the human and the macaque monkey, using an integrated and complimentary methods approach of invasive electrophysiology (Electrocorticography in human epilepsy patients [together with Bob Knight, UC Berkeley, and Josef Parvizi, Stanford] and simultaneous multi-site recordings in monkeys) with several brain imaging modalities (functional magnetic resonance imaging, diffusion tensor imaging). Our studies in the two primate brain models are done in comparison that is afforded by tasks showing an identical behavioral pattern. Additional lines of research in the lab include the neural basis of attentional selection from natural scenes, the functional parcellation of the human parietal cortex, and the neural basis of object perception (including studies with patients suffering from object agnosia and amnesia together with Marlene Behrmann, Carnegie Mellon).
Sabine Kastner studies the neural basis of visual perception, attention, and awareness using a translational approach that combines neuroimaging in humans and monkeys, monkey physiology and studies in patients with brain lesions. Dr. Kastner earned an M.D. degree from the Heinrich-Heine University of Duesseldorf (Germany) and received a Ph.D. degree in neurophysiology from the Georg-August University, Goettingen (Germany) under the mentorship of the late Otto Creutzfeldt. After a postdoc at the Max-Planck-Institute for Biophysical Chemistry, Goettingen and an internship in psychiatry, Dr. Kastner joined Leslie Ungerleider’s and Robert Desimone’s lab at the NIMH in Bethesda (1996-2000) before taking on a faculty position at Princeton, where she currently holds the rank of full professor. Dr. Kastner has served as the Scientific Director of Princeton’s neuroimaging facility since 2005. Dr. Kastner has published more than 100 articles in journals and books and has edited the Handbook of Attention (Oxford University Press, 2014). She is a Fellow of the American Psychological Society. Dr. Kastner’s contributions to the field of cognitive neuroscience were recognized with the Young Investigator Award from the Cognitive Neuroscience Society in 2005. Dr. Kastner serves on several editorial boards and is a Senior Editor for the Journal of Neuroscience.
