This workshop will present established and novel methods to generate evoked potentials recorded by EEGs. These procedures, some of them only recently developed, enable the detailed revealing of components of the somatosensory system. Providing objective results, they are especially advantageous over previously established methods such as Quantitative Sensory Testing.

Several stimuli are applied to the skin which are then processed centrally. This processing manifests as potentials in the simultaneously-recorded EEG. Thus, latencies and amplitudes can be measured and assigned to the respective fiber classes. This enables a dedicated assessment of the somatosensory system. Thus, pathologies can be uncovered – objectively.

In this workshop, cold, contact-heat, laser, and PinPrick stimuli are presented to facilitate a broad overview of the field of evoked potentials. The clinical relevance of these methods is discussed and explained in more detail by using exemplary cases. Next to appealing cases, the speakers will engage participants in discussions on how to prevent pitfalls both in assessing and interpreting evoked potentials. Participants will have the chance to apply stimuli independently and will be made familiar with EEG evaluation. They will also have the opportunity to perceive the various stimuli themselves. The relevance for clinical and scientific use will be discussed.
