How Senses Work Together: Cross-Modal Interactions between Primary Sensory Cortices

Figure 4

Whisker deprivation (WD) markedly enhances visual acuity and contrast sensitivity as measured in V1 using intrinsic signal imaging. (a) WD was performed by bilaterally removing the macrowhiskers on the snout (b) After WD for 12 days, visual acuity was increased by about 40%. (c) The same treatment led to a massive improvement of contrast sensitivity by 60%.
