Abstract:
Previous functional magnetic resonance imaging (fMRI) studies have demonstrated that the human visual motion area V5/MT+ is differentially activated by stimuli in which the presence of motion is implied by the content of static photographs, compared with similar static scenes in which no motion is implied. Here, using a group magnetoencephalography study, we confirm the role of V5/MT+ in the perception of implied motion (IM) by the measurement and localization of task-related evoked and induced oscillatory responses, and demonstrate the temporal sequence of these responses. Within the lateral occipital complex, including V5/MT+, statistically significant differential oscillatory responses to IM and implied-static (IS) stimuli were only found in the beta band (15-20 Hz). An early, evoked, beta power increase (IM>IS) occurred at about 150 ms, whilst a power decrease (IM

Motor and Sensory Areas of the Cortex
Motor Areas
The motor areas located in the frontal lobe are central to controlling voluntary movements. This region is further subdivided into the primary motor cortex and the premotor cortex.

Association Areas of the Cortex
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...
