About

Ehud Ahissar is a pioneering neuroscientist whose work fundamentally reshapes our understanding of active sensing and perception. His primary research areas include sensorimotor integration, vibrissal (whisker) systems in rodents, and the computational principles underlying closed-loop perception. Ahissar’s major contribution is the formulation of perception as a dynamic, closed-loop convergence process, challenging the traditional open-loop model of sensory processing. His highly cited 2016 paper on this topic (162 citations) argues that sensory organs are not passive receivers but active participants in a continuous feedback loop with the environment. He has also made seminal contributions to understanding the biomechanics of active touch, notably through his detailed analysis of the rat mystacial pad musculature (145 citations), which has informed both neuroscience and robotics. Beyond these, Ahissar explores reinforcement learning and hierarchical loops in curious agents, laying groundwork for autonomous learning systems. His work bridges biology and engineering, offering a powerful framework for designing intelligent, touch-oriented robots. With a career dedicated to unraveling how organisms actively construct their perceptual world, Ahissar’s research remains highly influential in cognitive science, computational neuroscience, and robotics.
