| Resumo: | The suprachiasmatic nuclei (SCN) are pointed to as the mammals central circadian pacemaker. Aged animals show internal timedisruption possibly caused by morphological and neurochemical changes in SCN components. Some studies reported changes ofneuronal cells and neuroglia in the SCN of rats and nonhuman primates during aging. The effects of senescence on morphologicalaspects in SCN are important for understanding some alterations in biological rhythms expression. Therefore, our aim was toperform a comparative study of the morphological aspects of SCN in adult and aged female marmoset. Morphometric analysis ofSCN was performed using Nissl staining, NeuN-IR, GFAP-IR, and CB-IR. A significant decrease in the SCN cells staining withNissl, NeuN, and CB were observed in aged female marmosets compared to adults, while a significant increase in glial cells wasfound in aged marmosets, thus suggesting compensatory process due to neuronal loss evoked by aging. |
