Informational capacity of the rat sensorimotor cortex in the postresuscitation period (morphometric analysis of a neuronal population)

Morphology and Pathomorphology


The number of neurons was counted in different functional neuronal complexes of the sensorimotor cortex in albino rats in the control and at different times after clinical death caused by asphyxia. A decrease of the number of neurons from 2.5×106 in the control to 1.56×106 toward the 30th day of the postresuscitation period was found in the sensorimotor cortex. The complexes of small neurons in the upper floor (layers II–IV) suffer badly, while the neurons of layer VI are damaged to a somewhat lesser degree and the cells of layer V are minimally altered.
