The role of right and left posterior parietal cortex in the modulation of spatial attentional biases by self and non-self face stimuli
In the present research we investigated whether the direction of the attentional bias in line bisection judgment displayed by healthy subjects is influenced by the evaluation of the social distance between self and other. We used inhibitory repetitive transcranial magnetic stimulation (rTMS) trains over the right and left parietal cortex to investigate the role of these regions in the task. Following right parietal rTMS, the self face is perceived as closer when it is located at the right line endpoint; following left parietal rTMS, the self face is perceived as closer when it is located at the left line endpoint. In both cases, the side of space ipsilateral to the rTMS is underestimated fr…
Temporo-parietal junction is involved in attribution of hostile intentionality in social interactions: an rTMS study.
The temporal-parietal junction (TPJ) is a brain area implicated in social cognition, attention, integrating body-related information and self-processing. We investigated involvement of both the left and the right TPJ in a complex social cognitive task that required attributing intentions to other people. Fourteen healthy subjects participated in experiments that involved simulating interactions with other people in everyday conflicting situations. The task was performed following application of inhibitory trains of repetitive transcranial magnetic stimulation (rTMS) to the right and the left TPJ and to a control occipital brain site. Results showed a different pattern of involvement for the…
