Autoradiographic assessment of [3H]proline uptake by neurons of epileptogenic mirror focus.


Epileptogenic mirror focus was produced in the left parietal area of the rat brain by cobalt implantation into the contralateral hemisphere. On the 14th day after cobalt implantation [3H]proline was injected into both experimental and control rats (without cobalt). The incorporation of [3H]proline in neurons of layers III and V of the parietal brain cortex and neurons of the nucleus lateralis thalami was investigated by the autoradiography technique. A statistically reliable increase in [3H]proline uptake was observed in neurons of layer III (31%) and in neurons of layer V (41%) of the epileptogenic mirror focus. The other neuronal types revealed no reliable changes. The morphological and functional aspects of the altered protein metabolism during epileptogenesis are discussed.
