PMID-16291944[0] Stable ensemble performance with single-neuron variability during reaching movements in primates.

  • correlation between the firing of single neurons and movement parameters was nonstationary over 30-60 minute recording sessions.
  • yet! you could get stable prediction of arm movements, suggesting that movement parameters are redundantly encoded.
  • this, in turn, implies that you do not need a stable recorded population for good predictions.
  • suggest that the variance itself could be a means of neuronal 'computation' or exploration based on perturbations.
    • later Carmena papers do not mention this.
