PMID-14511525 Probing changes in neural interaction during adaptation.

  • looking at the changes in te connectivity between cells during/after motor learning.
  • convert sparse spike trains to continuous firing rates, use these as input to granger causality test
  • used the Dawn Taylor monkey task, except with push-buttons.
  • perterbed the monkey's reach trajectory with a string to a pneumatic cylinder.
  • their data looks pretty random. 9-17 neurons recorded. learning generally involves increases in interaction.
  • sponsored by DARPA
  • not a very good paper, alas.
