Although it has long been known that right posterior parietal cortex (PPC) has a role in certain visual search tasks, and human motion area V5 is involved in processing tasks requiring attention to motion, little is known about how these areas may interact during the processing of a task requiring the speciality of each. Using transcranial magnetic… (More)
Figure 3. (a) Experiment 1. Search functions and rates for present responses in each task. Both tasks were carried out in a serial manner, however, the motion/orientation conjunction search was more efficient than the color/orientation conjunction. Errors shown are ± standard error of the mean (SEM). (b) Experiment 2. Differential involvement of right PPC and V5 on color/orientation conjunction and motion/orientation conjunction search tasks as shown by normalized (with respect to no TMS reaction times) reaction times. Right PPC is significantly impaired in processing of the color/form conjunction task but not the motion/form conjunction task with rTMS. The opposite pattern is seen with rTMS over V5. Error bars shown are ±SEM. * denotes significance to p\ 0.05; ** denotes significance to p\ 0.01.
