摘要：

Choline acetyltransferase (ChAT) was measured in the habenula and in the interpeduncular nucleus of rats from 1 to 12 weeks of age. A remarkable degree of parallelism was shown by the developmental curves in the two nuclei. In both cases the highest level of enzyme activity was reached at 3 weeks of age and was followed by some decrease towards adult values. A statistically highly significant correlation was demonstrated between ChAT levels in the two nuclei at the various developmental stages. The rise of the cholinergic marker was slightly advanced in the habenula in comparison with the interpeduncular nucleus. The present data may be useful for studies focused on neonatal synaptogenesis, plasticity and synaptic neurochemistry of this relatively simple model of brain connections. © 1990.
