Very few studies have examined covert attention in the absence of external somatosensory stimuli to produce top-down activations.
Top-down processes associated with sustained attention focused on different body parts induce cortex activation even in the absence of external stimulation. The brain areas associated have a left hemisphere tendency.
Further studies to differentiate between brain hemisphere dominance and a larger group sample are needed to sustain this idea.
