2010.02.19 - Eb Fetz - Applications of recurrent brain computer interfaces

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
