If action-language processing activates motor representations automatically, then motor activation should occur even when the participants' attention is diverted from the motor content of a word.
Figure 2 Transient perturbation generated by motor activation in scalar burst mode data.
The notion that conceptual processing is accompanied by perceptual and motor activation is relatively uncontroversial.
This study demonstrated that motor activation can be measured dynamically during a single FDG PET scan.
Pure motor activation during finger tapping with the reading hand showed expected precentral activation and no activation of visual cortex.
However, the patient groups, with chronic and acute migraine, also show dispersed neuromagnetic activation outside of the typical primary motor activation (Green arrows in Figs. 1 2).
However, the nature of such motor activation is unclear.
How does the matching of motor activation patterns occur?
Such motor-charged stimuli elicit (pre)motor activation; other more visually charged stimuli (e.g., animals) do not.
The authors observed that blood pressure, HR, and pulmonary ventilation increased less when central motor activation reduced, whereas the opposite was observed when central motor activation rose.
