Fig. 4From: Involvement of the endocannabinoid system in the physiological response to transient common carotid artery occlusion and reperfusionCyclooxygenase-2 (COX-2)-like immunoreactivity in the frontal cortex. Brain sections of sham-operated and BCCAO/R rats are shown in (a, b) and (c, d), respectively. b, d represent a higher magnification of the microscopic fields squared in (a) and (c), respectively. Panels (a–d) are representative of observations carried out in 6 sham-operated and 6 BCCAO/R rats. Positive cell bodies are mostly distributed in the superficial cortical layers. m, molecular layer; wm, white matter. Scale bars: 50 μmBack to article page
