If we agree that neurons send out stochastic signals, a natural question is then how we can achieve a precise control using a stochastic signals: a stochastic control task. In the past few years, we have worked on various control problems: mainly from optimal stochastic control point of view. The aim is to combine sensory inputs and information processing in neuronal networks (hence, all work above) to complete a control task (arm movement, for example) .
