description:
There are two runs for total 19 subjects. One is the “match” run which the visual angles of stimuli were matched in the near and far spaces, the other is the “natural” run which visual angles of stimuli were same in the near and far spaces. These datasets are mainly used to examining whether the parietal-occipital junction (POJ) acts as an interface for the integration and processing of information between the dorsal and ventral streams in the near and far space processing. we were most interested in the differential processing between the near and far spaces, we contrasted the near and far spaces processing (i.e., the ‘Near > Far’ contrast) and then conjoined the ‘Near > Far’ contrasts for the ‘match’ and ‘natural’ conditions, thus creating a near or far space preference region that was independent of object size. Then, we performed psychophysiological interaction (PPI) analysis to investigate the functional connectivity between the resulting region (POJ) and the dorsal and ventral streams. With the neural activity in the POJ as the physiological factor, and the ‘Near > Far’ contrast as the psychological factor, the results showed that the POJ show enhanced functional connectivity with both the dorsal and ventral streams during the far space processing.
