Digitimer DS7A Constant Current Stimulator

A DS7A constant current stimulator from Digitimer is available for recording various magnetic evoked fields.

DS7A

  • Magnetic evoked fields under stimulation:
    • Somatosensory Evoked Fields (SEF)
    • Auditory Evoked Fields (AEF)
    • Visual Evoked Fields (VEF)
    • Language Evoked Fields (LEF)
  • Magnetic evoked fields under voluntary activity:
    • Motor Related Fields (MRF)

Improper installation of the DS7A can result in an increase in sensor noise levels due to RF leakage and/or unwanted ground loops.

[Guidelines to MEG Data Acquisition] (SharePoint link to be added) provides more information.

The DS7A is located in the Stimulus Cabinet.
