Neuroimaging of movement representations: from blobs to content

I will address the issue of neural correlates of motor representations, in the context of interactions between action and perception. First I will review studies in which instructed delay tasks have been used to isolate neural activity related to motor preparation, temporally independent from instructions and responses. I will then move onto discussing a series of potential confounds implicit in that approach, touching on the context-dependent features of delay-related neural activity. I will conclude by addressing the issue of neural interactions between sensory- and motor-related responses.
