A Synergy in ISR

A Synergy in ISR

• There is opportunity for close cooperation
  between the study of (auditory) neuroethology,
  and research in communication, control, and
  signal processing.
• Challenges in understanding neuronal plasticity,
  learning, active sensing, neuromorphic
  computation and realization etc., can be
  addressed by engagement of the systems view
  models, signals, formal languages, feedback
  loops, and hierarchies (levels).
• In the area of auditory neuroethology these
  challenges are being addressed by collaborative
  teams within ISR, leading to fundamental
  insights, algorithms, and technological advances
  (e.g. in robotics)
