Area of Science:

  • Neurosurgery
  • Neurology
  • Motor Control Systems

Background:

  • Stereotactic surgery targets specific brain regions to alleviate motor disturbances.
  • Identifying optimal stimulation sites is crucial for effective therapeutic interventions.
  • Understanding the interplay between central and peripheral motor system states is essential.

Purpose of the Study:

  • To investigate the influence of various stereotactic target points on motor disturbances.
  • To develop and validate a system for investigating motor system states (resting and working).
  • To elucidate the functional dependency of elicited events within the motor system.

Main Methods:

  • Electrode implantation in key motor structures (VL, Vim, CM, P, dentate nucleus, motor cortex).

  • Recording of evoked potentials and motor effects in muscles.
  • Analysis of elicited events based on stimulation/registration site and muscle activity.

    • Main Results:

    • Different stereotactic targets can influence the same motor disturbance.
    • A developed investigation system effectively analyzes motor system states.
    • Centrally and peripherally elicited events exhibit mutual influence.
    • Functional dependencies within the motor system are explicitly demonstrated.

    Conclusions:

    • The study provides insights into basic motor functions.
    • The developed system aids in selecting optimal therapeutic targets.
    • Findings contribute to answering therapeutic questions in stereotactic neurosurgery.
