Topic: 7-Tesla fMRI

The tonotopic organization of the auditory system plays a crucial role in facilitating efficient processing of diverse auditory information that appears to be conserved across mammalian species. Approaches to date have mostly used electrophysiological or static approaches to map the representation of sound frequencies within the rodent auditory system, meaning that a comprehensive mapping in real-time was not feasible. Here, we used 7-Tesla fMRI in awake male rats to simultaneously determine tonotopic frequency representations in cortical and subcortical structures. Presentation of four differ
