Topic: tonotopic organization

Implementing bioinspired neural networks in silico is a powerful tool for studying brain processes. These networks grant access to the real-time behavior of individual neurons within a complex circuitry, such as the ones executing neurosensory functions. This study proposes a computational model to study how the mammalian brainstem implements sound localization: the ability to identify an acoustic source in the surrounding space. The main actors in sound localization are two brainstem nuclei: the medial and the lateral superior olive. We have reconstructed a model made of thousands of spiking

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
