This research article investigates the role of the auditory cortex in pure-tone intensity processing, focusing on tone detection and loudness perception. The study involved a middle-aged man with bilateral lesions of the auditory cortex and a control group of healthy adults. Results indicated that the auditory cortex is crucial for fine-grained loudness discrimination but not necessary for tone detection in quiet environments. The study suggests a dissociation between auditory sensation and perception, with the auditory cortex playing a critical role in the latter.
