c-fos gene expression parallels auditory adaptation in the adult rat.
This study investigated the pattern of c-fos gene expression corresponding with auditory adaptation to novel sound. Using six groups of adult rats (naive control, 1 h, and 1, 2, 3, and 4 days of continuous stimulation), we quantified c-fos expressing cells in the dorsal and ventral cochlear nuclei and found a 54 fold increase in 1 h following novel sound stimuli. The number of reactive cells decreased sharply within 24 h and nearly disappeared by 96 h. Our results reveal that c-fos gene expression in the adult rat is attenuated in parallel with the expected auditory adaptation to novel sounds indicating an association with auditory learning and memory.
