The paper estimates 2D spatio-tactile population receptive fields in human BA3b using fMRI and finds that the ulnar-to-radial fingertip axis maps to a superior-to-inferior axis in BA3b.

This study investigates age-related changes in cortical layer architecture and sensory function across species, finding layer-specific alterations in myelination and neuronal activity.

The paper uses 7T MRI to analyze 3D structural features in the human hand area of S1 and finds no topographic organization, unlike in some monkeys.

This study examines de-differentiated topographic maps in somatosensory cortex of younger and older adults using fMRI and behavioral tests, finding that reduced representational similarity and altered cortical distances correlate with specific behavioral changes.
