THE COGNITION-EMOTION NEUROSCIENCE LABORATORY (CENSL)
Dr. Keedy’s lab, the CENSL, focuses on cognitive and emotional neural systems - and their overlap - in patients with psychiatric disorders as well as in healthy individuals. CENSL utilizes highly sensitive neurophysiological and neurocognitive methods. A major area of focus for this work is in psychotic disorders, Dr. Keedy’s area of expertise, including schizophrenia, schizoaffective disorder, and bipolar disorder. CENSL also currently supports work in aggression, personality, anxiety, eating disorders, HIV, development, and other areas.
The CENSL Neuroimaging Core (CENSL-NC) is a group of academics, staff, and students led by Dr. Keedy. Collectively, they provide support for functional and structural MRI and EEG research for Dr. Keedy's work and for her collaborators. Collaborators include all faculty in the Clinical Neuroscience and Psychopharmacology Research Unit in the Department of Psychiatry and Behavioral Neuroscience, where CENSL is housed, as well as other faculty in Psychiatry, Psychology, Medicine, and beyond. CENSL-NC support includes task development consultation and programming, training on practical aspects of data acquisition and analysis, or direct provision of analysis, data interpretation, and manuscript or grant preparation.
For MRI research, CENSL-NC utilizes the University of Chicago’s Brain Research Imaging Center (BRIC), which includes hardware for functional imaging that may include visual and auditory stimuli, button box responses, in-scanner eye tracking, and more. For EEG, CENSL utilizes a BioSemi Active Two EEG system with capacity for up to 128 channels. For EEG analysis, the lab has licenses for BESA Research, Statistics, and MRI. All MRI or EEG UNIX-based analyses are conducted on the Research Computing Center’s Midway supercomputer, as well as via a locally-maintained UNIX system. Lab expertise includes use of SPM, AFNI, FSL, Matlab, Presentation, E-Prime, and other packages.
Ongoing training in fMRI and EEG task design or analysis occurs via weekly meetings of the Neuroimaging Core where project ideas are discussed, preliminary analyses are included, or formal seminars are conducted.
Dr. Keedy has mentored students at numerous phases and from different programs via laboratory experiences and focused projects, including undergraduates in the Katen Scholars summer program, Pritzker medical students in the Summer Research Program and in the Scientific Investigation Track, graduate students in neuroscience (Dr. Keedy is a faculty member of the Committee on Neurobiology), clinical psychology externs, bioengineering, psychiatry residents, clinical psychology interns (offering a rotation as part of the clinical psychology internship), and postdocs. Please email Dr. Keedy with a specific inquiries regarding training opportunities or for inquiries on collaborating on MRI and EEG projects.
