Spatial organization of frequency preference and selectivity in the human inferior colliculus
To date, the functional organization of human auditory subcortical structures can only be inferred from animal models. Here we use high-resolution functional magnetic resonance imaging at ultra-high magnetic fields (7T) to map the organization of spectral responses in the human inferior colliculus, a subcortical structure fundamental for sound processing. We reveal a tonotopic map with a spatia...
متن کاملTonotopic Organization in the Depth of Human Inferior Colliculus
Experiments in animal models indicate that inferior colliculus (IC), the primary auditory midbrain structure, represents sound frequency in a particular spatial organization, a tonotopy, that proceeds from dorsal and superficial to ventral and deeper tissue. Experiments are presented that use high-resolution, sparse-sampling functional magnetic resonance imaging (fMRI) at 3 T to determine if to...
متن کاملNeuronal Organization in the Inferior Colliculus
An understanding of the neuronal organization of the inferior colliculus (IC) requires an exploration of how the types of neurons, the microcircuitry, and the synaptic organization of the IC interact to define functional zones. The IC was originally divided using anatomical methods to identify the neurons and their inputs with the hope that these subdivisions would correspond to functional zone...
متن کاملSpatial selectivity and binaural responses in the inferior colliculus of the great horned owl.
In this study we have investigated the processing of auditory cues for sound localization in the great horned owl (Bubo virginianus). Previous studies have shown that the barn owl, whose ears are asymmetrically oriented in the vertical plane, has a 2-dimensional, topographic representation of auditory space in the external division of the inferior colliculus (ICx). As in the barn owl, the great...
متن کاملSpike-frequency adaptation in the inferior colliculus.
We investigated spike-frequency adaptation of neurons sensitive to interaural phase disparities (IPDs) in the inferior colliculus (IC) of urethane-anesthetized guinea pigs using a stimulus paradigm designed to exclude the influence of adaptation below the level of binaural integration. The IPD-step stimulus consists of a binaural 3,000-ms tone, in which the first 1,000 ms is held at a neuron's ...
