DESCRIPTION:Perception of external objects involves sensory acquisition vi
 a the relevant sensory organs. A widely-accepted assumption is that the se
 nsory organ is the first station in a serial chain of processing circuits 
 leading to an internal circuit in which a percept emerges. This open-loop 
 scheme\, in which the interaction between the sensory organ and the enviro
 nment is not affected by its concurrent downstream neuronal processing\, i
 s strongly challenged by behavioral and anatomical data. I will present a 
 hypothesis in which the perception of external objects is a closed-loop dy
 namical process encompassing loops that integrate the organism and its env
 ironment and converging towards organism-environment steady-states. I will
  discuss the consistency of closed-loop perception (CLP) with empirical da
 ta\, show that it can be synthesized in a robotic setup\, and discuss poss
 ible empirical ways to discriminate between open- and closed-loop schemes 
 for perception.
