Area of Science:

  • Neurosurgery
  • Neuroimaging
  • Cognitive Neuroscience

Background:

  • Functional brain mapping is crucial for preoperative planning and intraoperative neurosurgical decision-making.
  • Traditional methods like direct electrical stimulation are complemented by advanced techniques such as functional magnetic resonance imaging (fMRI).
  • Less invasive imaging allows for more frequent mapping in broader subject populations, including healthy individuals and across different surgical time points.

Purpose of the Study:

  • To highlight the utility of functional brain mapping in neurosurgery.
  • To emphasize the integration of multiple brain mapping techniques for enhanced surgical planning.
  • To explore the potential of advanced imaging for understanding brain function and plasticity.

Main Methods:

  • Utilizing "gold standard" functional studies like direct electrical stimulation and recording.
  • Employing less invasive techniques, including functional magnetic resonance imaging (fMRI).
  • Integrating data from multiple complementary anatomical and physiological sources.

    • Main Results:

    • Functional imaging techniques successfully map critical brain areas (motor, sensory, language, memory) in patients with various neurological conditions.
    • The combination of multiple mapping techniques provides convergent evidence for improved decision-making.
    • Expansion of mapping tools enables more comprehensive pre- and postoperative assessments.

    Conclusions:

    • Functional brain mapping, especially with advanced imaging, significantly aids neurosurgical planning and intraoperative guidance.
    • The convergence of data from diverse mapping techniques enhances the precision of surgical interventions.
    • Future applications include planning minimally invasive procedures and gaining novel insights into brain plasticity and disease biology.
