TABLE 1.
Spillover of Radioactivity Between Lateral Geniculate Nucleus (LGN) Laminae1
| Ratio of radioactivity in non-labeled to labeled laminae |
|||
|---|---|---|---|
| Injection age | Sacrifice age | Ipsi-LGN A/A1 | Contra-LGN A1/A |
| P23 | P30 | 0.41 (104/100) | 0.60 (78/56) |
| P22 | P30 | 0.25 (95/100) | 0.45 (100/100) |
| P30 | P37 | 0.28 (68/63) | 0.37 (103/100) |
| P43 | P50 | 0.17 (100/99) | n/a |
| P71 | P81 | 0.14 (101/100) | 0.16 (100/100) |
Ratio of the number of nuclear silver grains per nuclear area in the unlabeled lamina to that in the labeled lamina. A and A1 refer to LGN laminae, which, respectively, receive contralateral and ipsilateral eye inputs. The numbers of LGN cell nuclei over which silver grain densities were measured in the nonlabeled and labeled laminae are shown in parentheses.
