Figure 4.

WT mice show expansion of functional cortical whisker representation after sensory deprivation, assessed with 2-DG metabolic labeling. Examples of 2-DG labeling of the barrel field in tangential slices of the somatosensory cortex of WT mice. a, Functional representation of row E of the left (control) pad (arrow) in the right hemisphere. b, Functional representation of the right (experimental) row E in the left hemisphere after 1 month of sensory deprivation. Note that the functional representation of row E in b is larger than that in a. Scale bar, 1 mm.
