Airborne copper exposure in school environments associated with poorer motor performance and altered basal ganglia
Pujol, J., Fenoll, R., Macià, D., Martínez-Vilavella, G., Alvarez-Pedrerol, M., Rivas, I., Forns Guzman, J., Deus, J., Blanco-Hinojo, L., Querol, X., & Sunyer, J. (2016). Airborne copper exposure in school environments associated with poorer motor performance and altered basal ganglia. Brain and Behavior, 6(6), Article e00467. https://doi.org/10.1002/brb3.467
Higher copper exposure was associated with poorer motor performance and altered structure of the basal ganglia. Specifically, the architecture of the caudate nucleus region was less complete in terms of both tissue composition and neural track water diffusion. Functional MRI consistently showed a reciprocal connectivity reduction between the caudate nucleus and the frontal cortex. The results establish an association between environmental copper exposure in children and alterations of basal ganglia structure and function.
