Mariano Sigman was born in Argentina and grew up in Barcelona, Spain. He obtained a master degree in physics at the University of Buenos Aires and a PhD in neuroscience at the Rockefeller University, with Charles Gilbert, investigating how the cortex organizes to assemble the statistics of the visual world, vast cultural changes (such as reading) and dynamically multiplex several functions through addressing mechanisms and top-down control. He moved to Paris as a Human Frontiers Fellow, investigating with Stanislas Dehaene decision making, cognitive architecture and consciousness.
