- Brain adapts to control of external devices
- metaphor for self controlling body
- Capable of independent control of neighboring neurons
- both increase and decrease firing rate
- Capable of isolating motor cortex cell from muscles (bidirectional)
- DC, frequency, single units are being used for brain computer interfaces
- Quickest learning seems to be in distal muscles of motor cortex
- Why does BCI suck?
- Complex transforms of multi-unit activity may complicate the control
- Independent control is impossible due to ensemble interactions
- Lack of proprioception may create ataxic effect
- Not enough time to learn patterns
- In free behaviors muscles are coactivated
- Brain is highly plastic don't have to pick anatomic locations
- Operant conditioning using BCI and other input signals
