Experiments were thus conducted to determine whether or not this aging effect was exclusive to the cortex or if it was apparent in subcortical structures such as in the inferior colliculus (IC). Experiments were made on 18 young (3-4 months) and 12 old (24-30 months) male Long Evans hooded rats. All stimuli were generated and data collected by a computer using the MALab system. The obtained data indicate that aging does not seem to affect FM speed selectivity at the level of the IC. ER -
