Chemogenetic inhibition of prefrontal projection neurons constrains top-down control of attention in young but not aged rats

Duggan MR, Joshi S, Strupp J, Parikh V (2021) Chemogenetic inhibition of prefrontal projection neurons constrains top-down control of attention in young but not aged rats. Brain Struct Funct 226(7):2357-2373. doi: 10.1007/s00429-021-02336-2

Objective: To test the hypothesis that reduced PFC output would exert differential effects on attentional capacities in young and aged rats, with the latter exhibiting a more robust decline in performance.

Summary: There is a reduced efficiency of PFC-mediated top–down control of attention and cholinergic system in aging, and that activity of PFC output neurons does not reflect compensation in aged rats, at least in the attention domain.
