Bilateral auditory cortex ablation alters the tonotopic organizaiton of the inferior colliculus

Traditional Poster Session - Functional MRI (Neuro): fMRI: Activation: no. 3045bSSFP fMRI with swept source imaging paradigm was applied on the experimental and age-matched control group to examine the effect of bilateral auditory cortex ablation on the tonotopic organization in inferior colliculus (IC). The differences between the changes of encoded frequency along the tonotopic axis suggested the tuning curve bandwidth center was shifted toward different directions for neurons at different portions of the IC. This study clearly demonstrated that cortical input can modulate the tonotopic organization in IC.link_to_OA_fulltex
