Dynamics of changes in morphometric parameters of the capillary bed of various divisions of the cerebral cortex during exposure.
In capillaries motosensornoy and in the visual cerebral cortex of the brain of laboratory animals as a result of vertical vibration with a frequency of 44 Hz and 8 Hz during 7,21,56 days observed alteration of microcirculation of the cerebral cortex, which translates into greater length, reducing the number and diameter of the capillaries. In this case, the severity of the processes is directly proportional to duration of the experiment. Changes in morphometric parameters of the capillary bed in the deep layers of the cortex are more significant and occur at an earlier date than in the surface. Frequency 44 Hz change indicators length, number and diameter of the capillaries to a greater extent than the frequency of 8 Hz. Severity adjustment processes of microcirculation in the sensorimotor cortex significantly more than in the visual and occur at earlier stages of the experiment.
