This revealed greater pre-stimulus beta-band desynchronisation and increased cerebellar-to-somatosensory connectivity before self-touch compared to misaligned touch.

As expected, self-touch evoked weaker somatosensory activity (as early as 50ms) compared to external and misaligned touch.

We compared the same touch under three conditions:

1. externally generated touch (no movement)

2. self-touch 👉👈

3. misaligned touch 👉 👈 (same movement, disrupted tactile prediction)

Movement kinematics were matched between self-touch and misaligned touch conditions 😎
