To advance the investigation of function and structure in human somatosensory areas, detailed topographic maps that are reproducible across time are invaluable. In previous 7 Tesla fMRI studies using travelling wave (TW) and event-related (ER) paradigms, the functional parcellation of digit representations in human S1 has been shown. Here, we present the application of ‘population Receptive Field’ analysis (pRF) to high-resolution fMRI data from somatosensory cortex. The pRF method can provide information beyond preferred stimulus location, such as measures of receptive field size. We also show how surface coils can be used to improve spatial resolution in somatotopic maps.
