Comparative analysis of cytoarchitectonic and neurochemical aspects of the globus pallidus in the rock cavy ( Kerodon rupestris ) and the common marmoset ( Callithrix jacchus )

Lavínnya Yáskara de Aquino Matoso, Yasmin Pinto Fernandes Albuquerque, Karina Maia Paiva, Rodrigo Freire Oliveira et autres

The globus pallidus (GP), a subcortical structure within the basal ganglia, plays a crucial role in modulating cortico-subcortical circuits related to motor control and associative/limbic functions. However, the cytoarchitectonic and neurochemical organization of this structure remains poorly characterized in naturally existing wild-type …
