Morphometric parameters of pial vessel bed in somatosensory (region 1) and parietal (middle third of f. supra-sylvii) zones of the right brain hemisphere were determined using automatic image analysis in acute experiments on normal cats and during 1-hour cooling blockade of the same regions in the left hemisphere. In normal conditions values of pial vessel bed area were higher in the somatosensory zone, with the vessels 16-50 micron in diameter prevailing. In the parietal zone vessels with a diameter of 5-15 micron prevailed. Primary vessel constriction was observed during cooling. Later the tendency to prolonged increase of specific bed length in the parietal zone, particularly during cooling of the symmetrical region, was noted. The data obtained reveal structural and functional peculiarities of pial system in associative and projection cortical zones and their significance in compensatory-restoration process after injury. |
