• Attending to tactile stimulation modulates primary somatosensory cortex, S1.
• High-resolution fMRI at 7T can measure fingertip specific attentional modulation.
• This modulation is somatotopically appropriate and directly linked to task-relevance.
• Such measurements are critical for examining neural mechanisms of somatosensation.
