in our attempt to identify these putative cell lines , we sought to meet the following criteria : ( 1 ) a good match between the time course of mitotic activity in a neuroepithelial sublobule and the birth days of neurons in the nucleus that it is postulated to supply with neurons , ( 2 ) relative proximity between the putative neuroepithelial source and the thalamic target structure , and , where possible , ( 3 ) the tracing of migrating cells from the germinal source to its destination .
