Design outcomes

Primary

Measure	Time frame
The main study parameter in Experiment 1 is the somatosensory evoked potential recorded bilaterally from EEG electrodes over the primary and secondary somatosensory cortices. In particular, we are interested in differences between ipsilateral SEPs evoked during self-touch as compared to external touch. These differences would indicate inter-hemisphere interaction as a result of self-touch. Similarly, the main study parameter in Experiment 2 is the difference in the pattern of evoked potentials whilst subjects are experiencing an illusion of mild thermal pain, recorded on the entire scalp during self-touch as compared to external touch.	—

Secondary

Measure	Time frame
We will not have secondary study parameters. However, we will analyze several distinct characteristics of the evoked SEPs (Exp 1) and ERPs (Exp 2), including raw waveforms, trial-locked synchronization, and interhemispheric coherence.	—
