In this study we used functional magnetic resonance imaging to investigate feature-based attentional modulations when attention was directed to speed vs. coherence of a moving dot field. Subjects were presented with a squared aperture located in the center of the upper visual field in which 100 dots moved at two different speeds (4,3 and 10,1°/s) and coherence levels (50 and 80%). When cued to attend to speed they were required to make a button press upon fast movement regardless of the coherence. When coherence was the relevant feature they had to press the button upon the occurrence of 80% coherence regardless of the speed. Behavioral data showed that the discrimination of coherence of motion was more difficult than the discrimination of speed. When attention was directed to the speed of motion enhanced neural activity was observed in lower-tier areas such as V3a and in the default mode network. However, attention to motion coherence produced enhanced hemodynamic activity in higher-tier areas in the intraparietal sulcus. These findings suggest that attention specifically boosts processing in the lowest-tier regions able to perform the task-critical discrimination.
