PMID-19660668[0] Functional neurosurgery for movement disorders: a historical perspective.

  • Spinal cord LFS (30 Hz) has been used to treat intractible pain for decades.
  • Based on experimental data obtained in MPTP-treated parkinsonian monkeys, the pedunculopontine nucleus has been used as a new target, and as suggested by the animal research results, its use indeed improves walking and stability when stimulation is performed at low frequency (25 Hz).
    • But donesn't it induce feelings of well-being {1074}
  • On freezing gait, which is non-dopamergic and not treated via STN DBS:
    • Based on experimental data obtained in MPTP-treated parkinsonian monkeys, the pedunculopontine nucleus has been used as a new target, and as suggested by the animal research results, its use indeed improves walking and stability when stimulation is performed at low frequency (25 Hz)
  • Many channel IPGS can target multiple structures with multiple frequencies; author thinks this is the future in terms of efficiency.
  • Suggests brain-machine interfaces (?)

PMID-21867795[0] Deep brain stimulation: BCI at large, where are we going to?

  • Everybody on the bandwagon! Talks about their efforts to make a BCI using DBS techniques / electrodes.
  • Language is a bit telegraphic, perhaps because it's translated from the French.
  • Tested in rats using an 1D ECoG BMI.
  • Posits that DBS is just a particularly simple form of BMI.

PMID-16280671[0] Deep-brain stimulation in Parkinson's disease: long-term efficacy and safety - What happened this year?

  • 260 reports on DBS in 2004!
  • (from the abstract) There is an urgent need for the organization of research and reports, and no need to report small series replicating well-established conclusions. oopsie.
  • Clinical reports should concentrate on unobserved effects in relation to causative parameters, based on the precise location of electrodes,
  • and on clinical reports comparable between teams and on methods to optimize and facilitate the tuning of parameters and postoperative evaluations in order to make this treatment easier to provide for the neurologist
