  • CARTA: Development and Evolutionary Specializations of Human Cognitive Networks with Nenad Sestan

    CARTA: Development and Evolutionary Specializations of Human Cognitive Networks with Nenad Sestan
    Apr 17 2026
    The extraordinary abilities of the cerebral cortex are central to what sets humans apart from other species. A defining feature of the cortex is its organization along a sensorimotor-to-association (S–A) axis, extending from primary sensorimotor areas to transmodal association regions that support abstract cognition. This axis varies across species and has been profoundly remodeled in humans. Nenad Sestan, professor of neuroscience at Yale, discusses his recent work on the molecular and cellular mechanisms that govern the development and evolution of the cortical S–A axis, with particular emphasis on the prefrontal cortex and its broader distributed transmodal association networks as well as their evolutionary expansion, functional roles, and vulnerability in neurological and psychiatric disorders.

  • Is This Your Only Life?

    Is This Your Only Life?
    Apr 17 2026
    Embodiment affects how we understand personhood, moral status, and whether this life is our only life. Mark Johnston, Henry Putnam University Professor, Princeton University, explains how competing theories of mind and matter shape the question of whether a will could have an embodiment other than its present one. Johnston examines the failures of functionalism, reductive and non-reductive materialism, and strong emergence, along with the role of will, awareness, and evolved animal life, helping clarify what embodiment really is. He explains why the will matters for moral respect and points toward the possibility that embodiment may not be limited to a single life.

  • CARTA: The Costs of Big Brains with Alex Pollen

    CARTA: The Costs of Big Brains with Alex Pollen
    Apr 15 2026
    Human brain expansion is often discussed in terms of the genetic and molecular innovations that drove uniquely human cognitive abilities. Yet evolution is fundamentally a process of tradeoffs. Disproportionate expansion of forebrain structures increases the demands placed on long-range connectivity, metabolism, and cellular maintenance, imposing costs that scale with brain size. Alex Pollen, associate professor of neurology at UC San Francisco, discusses using stem-cell-derived brain organoids to investigate the development of human-specific connectivity differences in dopaminergic neurons and to test whether these cells deploy compensatory mechanisms to cope with the metabolic and structural demands of large brains. His research findings support a model in which human brain evolution involves not only mechanisms driving greater computational capacity, but also the emergence of cellular adaptations that mitigate the costs of large, highly connected brains.
