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
