A new MR-compatible device enables precise tactile facial stimulation during fMRI. This tool effectively maps somatosensory brain activations, distinguishing between face and hand representations in the primary somatosensory cortex (S1).

Area of Science:

  • Neuroscience
  • Biomedical Engineering

Background:

  • Functional magnetic resonance imaging (fMRI) presents technical challenges for standardized somatosensory stimulation due to magnetic field interference and head coil constraints.
  • Quantitative sensory testing (QST) methods, like von Frey-filaments, are crucial for precise tactile stimulation but require MR-compatible adaptations for in-scanner use.

Purpose of the Study:

  • To develop and evaluate a novel computer-controlled, MR-compatible stimulation device for mapping somatosensory-evoked brain activations during fMRI.
  • To assess the device's capability in delivering punctate tactile stimuli with high spatiotemporal accuracy to the face and other body surfaces.
  • To compare the effectiveness of event-related versus blocked experimental designs for somatosensory mapping using the new device.

  • Development of a computer-controlled, MR-compatible device utilizing von Frey-filaments for punctate tactile stimulation.
  • Application of stimuli to the ipsilateral face and hand of eight volunteers during fMRI.
  • Comparison of an event-related design with a blocked design to evaluate somatosensory mapping efficacy.

    • Main Results:

    • The novel stimulator successfully activated a distributed neural network, including primary (S1) and secondary (S2) somatosensory areas, premotor cortex, and thalamus.
    • An event-related design consistently identified S1 activation across all subjects, whereas the blocked design showed less consistent S1 activation.
    • Punctate tactile stimuli enabled discrimination of face and hand representations within S1 when significant activation was observed.

    Conclusions:

    • The developed MR-compatible stimulation device is a valuable tool for mapping somatosensory representations during fMRI.
    • An event-related study design appears more beneficial for somatosensory mapping, offering better control over confounding factors like anticipation and habituation.
