Research interests

Computational Neuroscience

  • Closed loop temporal sequence learning / control.

    Autonomous agents control their inputs and not their outputs.
    This becomes clear with the chicken-egg problem #2: The chicken wants to keep the egg. The farmer, however, wants to have the egg. While the chicken perceives itself as a closed loop system the farmer perceives the chicken as an open loop system: input (food), put-put and output (egg).
  • How can a reactive system turn itself into a proactive system?
  • Limbic system
  • Spike timing dependent plasticity
  • Constructivist models of temporal sequence learning.
  • Robotics
  • Applications of control/signal theory in the field of CN
  • Embodiment
  • Deep brain stimulation
  • Wireless transmission of bio signals
  • Image processing
