John M. Allman

John M. Allman is the Frank P. Hixon Professor of Neurobiology at the California Institute of Technology. He holds a B.A. from the University of Virginia (1965), A.M. and Ph.D. from the University of Chicago (1968, 1971). Since 1974, he has held progressively senior roles at Caltech, culminating in his current Hixon Professorship since 1989.

His research focuses on brain evolution through comparative neuroanatomy, with particular emphasis on the role of Von Economo neurons in social decision-making and economic behavior. The Allman Lab investigates these neurons' distribution in humans and apes, their potential role in rapid intuitive choices, and parallels in highly social species like African elephants. Collaborations include Prof. Barbara Wold (RNA-Seq analysis of Alzheimer's-related gene expression), Prof. Long Cai (FISH subcellular visualization), and Prof. David Bennett (Alzheimer's pathology studies).

Publications highlight advancements in cortical microstructure imaging, THC neuroplasticity effects, and psychiatric disorder brain connectivity. His work bridges evolutionary biology, cognitive neuroscience, and clinical neurology, with contributions to understanding both normal and pathological brain function across species.

Key collaborations include the Rush Alzheimer's Disease Center and ex vivo tractography studies in primates. Current projects extend from molecular gene expression studies to large-scale brain network analyses, maintaining a translational focus between basic research and clinical applications.
