Changes in cortical (circles) and medullary (triangles) laser Doppler values in denervated (n = 7, open symbols) and control (n = 7, filled symbols) animals. Data are presented as mean ± SEM. #p < 0.05 cortical laser Doppler denervated vs. control., *p < 0.05 cortical laser Doppler vs. baseline in denervated animals, §p < 0.05 cortical laser Doppler vs. baseline in control animals, $p < 0.05 medullary laser Doppler vs. baseline in denervated animals, &p < 0.05 medullary laser Doppler vs. baseline in control animals. To avoid the risk of traumatic injury, probes were inserted after surgical denervation
