Fascinating and ground breaking work. I don't think we've ever looked at sinle neuron activity in the human thalamus before.
Thalamus for vision BCIs
Scientists have recorded single neurons in the human LGN for the first time, revealing how it links the retina to visual cortex. When one eye is closed, neurons tuned to that eye reduce their activity, while neurons tuned to the open eye increase in spikerate

With adaptive deep brain stimulation getting FDA approved, we should see more closed loop control algorithms rather than proportional integral or on/off switching controllers. One method is called direct data driven model predictive control.
