The role of the right temporoparietal junction in the control of imitation.
Bottom Line: Brain imaging studies have implicated the right temporoparietal junction (rTPJ) in this ability, but causal evidence for its role is lacking.A debate is also ongoing regarding whether the control of, or switching between, self and other representations is a specialized or domain-general process: the rTPJ's well-established role in reorienting attention supports a domain-general process, but a role specific to social cognition has also been proposed.This suggests that the rTPJ is involved in switching between self and other representations, and further, that this process may not be entirely domain general.

Mentions: Crucially, there was a significant interaction of site by imitative compatibility; F1,15 = 5.10, P = 0.039, η2 = 0.25 and no significant interaction of site by spatial compatibility; F1,15 < 1, P = 0.647, η2 = 0.01. No other main effects or interactions reached significance (all P > 0.05). Figure 2 shows the spatial compatibility and imitative compatibility effects for both rTPJ and MO stimulation sites, indicating a similar spatial compatibility effect across both stimulation sites, but a larger imitative compatibility effect during stimulation to the rTPJ than the control MO site. Therefore, rTMS to the rTPJ impaired participants' ability to control the tendency to imitate, but not their ability to control spatial response tendencies.Figure 2.
