Cortical stimulation mapping (CSM) using multiple tasks, including auditory naming, identifies more language sites than visual naming alone, especially in temporal regions. A multimodality approach may improve language site preservation during epilepsy surgery.

Area of Science:

  • Neuroscience
  • Epileptology
  • Neurosurgery

Background:

  • Cortical stimulation mapping (CSM) typically uses visual naming for epilepsy surgery in the dominant hemisphere.
  • Visual naming may not detect all language sites in critical resection areas.
  • Additional tasks are needed for comprehensive language mapping.

Purpose of the Study:

  • To compare word-finding distinctions across visual, auditory, and reading modalities during CSM.
  • To determine the percentage of modality-specific language sites in dominant hemisphere subregions.

Main Methods:

  • Twenty-eight epilepsy patients underwent CSM using visual, auditory, and sentence-completion tasks.
  • Hierarchical logistic regression analyzed errors to identify language sites.
  • Modality-specific percentages were calculated within subregions.

Main Results:

  • Auditory naming identified twice as many language sites in anterior temporal regions compared to visual naming.
  • Distinct language sites were found for different input modalities (95 auditory, 48 visual).
  • Sentence completion showed fewer language sites in temporal areas compared to visual and auditory tasks.

Conclusions:

  • Distinct cortical areas subserve different language input modalities.
  • Auditory naming is crucial for identifying language sites in anterior temporal regions.
  • A multimodality CSM approach may be necessary to preserve language function during epilepsy surgery.
