2024 Krieg Cortical Kudos
Below are the 2024 winners of the Krieg Cortical Kudos awards in the three categories of Scholar, Explorer and Discoverer.
Discoverer
John Morrison
UC Davis Distinguished Professor, Core Scientist at the California National Primate Research Center (CNPRC), and Professor of Neurology in the School of Medicine at UC Davis
Dr. Morrison earned his Bachelor’s Degree from Johns Hopkins University and Ph.D. from the School of Medicine at Johns Hopkins University, and completed postdoctoral studies at the Salk Institute for Biological Studies. He then served as a faculty member at The Scripps Research Institute until he joined the faculty at Mount Sinai in 1989 where he went on to be Chair of the Department of Neuroscience and serve as Dean of Basic Sciences and the Graduate School of Biomedical Sciences at Mount Sinai before moving to UC Davis in 2015. Dr. Morrison has served on Council for the Society for Neuroscience (SfN), as Editor-in-Chief of SfN’s public-facing website, BrainFacts.org, Secretary of SfN, and is currently serving as President of SfN.
Dr. Morrison’s research program focuses primarily on the neurobiology of aging and neurodegenerative disorders, particularly as they relate to cellular and synaptic organization of cerebral cortex. His laboratory is particularly interested in age-related alterations in structural and molecular attributes of the synapse that compromise synaptic health, lead to cognitive decline, and potentially leave the brain vulnerable to Alzheimer’s Disease (AD). In recent years, Dr. Morrison has developed and characterized both amyloid and tau-based nonhuman primate (NHP) models of AD. In addition, he has been studying neuro-invasive viruses such as SARS-CoV-2 in NHP models and is now pursuing mechanistic links between COVID-19 and risk of onset and acceleration of AD neuropathology.

Cory Miller
Professor, University of California, San Diego
"The core mission of our lab’s research is to elucidate the neural basis of natural behavior. Our research philosophy is that significant insights into the cellular, circuit and computational mechanisms in the brain will come from examining neural processes as individuals are confronted with the very challenges their brains were optimized over evolution to solve. We approach this topic by developing experimental paradigms that leverage different ethological behaviors in the species repertoire – including social communication, spatial navigation and active vision – to investigate the supporting neural systems. Research in the lab is directly complemented by parallel studies of wild animals in their natural habitat that provide invaluable insights into how the same behaviors manifest in different ecological conditions."

Dr. Carol Mason Receives Krieg Lifetime Achievement Award
CAROL MASON, PhDProfessor of Pathology and Cell Biology, Neuroscience and Ophthalmic Science (in Ophthalmology) Principal Investigator and Chair of Interschool Planning at Columbia's Zuckerman Institute
CELEBRATING A CAREER OF EXCELLENCE
The Krieg Lifetime Achievement Award was presented to Dr. Carol Mason at the recent 75th Anniversary celebration of the Cajal Club. This award, which is not given every year, is given infrequently to honor exceptional contributions in the field of science. The award was a unanimous decision made by the Cajal Club Officers and Board of Directors.
Dr. Larry Swanson presented the award to Dr. Mason, and this award serves as a testament to her outstanding contributions and dedication to the field of science. On behalf of the Cajal Club, we extend our warmest congratulations to Dr. Carol Mason on this well-deserved recognition.
Biography: Dr. Carol Mason is a researcher at Columbia's Zuckerman Mind Brain Behavior Institute studies the circuitry of the visual system. She focuses on the retinal ganglion cells (RGCs), which extend from the retina to the thalamus and midbrain, where signals are sent to the visual stations in the cortex. Half of the RGCs send their axons to the same side of the brain while the other half cross over, allowing for binocular vision. Dr. Mason is investigating how the axons know whether to cross over or remain on the same side at the optic chiasm.
