Cortical modulation of auditory processing in the midbrain [PDF]
Frontiers in Neural Circuits, 2013 In addition to their ascending pathways that originate at the receptor cells, all sensory systems are characterized by extensive descending projections. Although the size of these connections often outweighs those that carry information in the ascending ...

Mixed Representations of Sound and Action in the Auditory Midbrain. [PDF]
J Neurosci, 2023 Linking sensory input and its consequences is a fundamental brain operation. During behavior, the neural activity of neocortical and limbic systems often reflects dynamic combinations of sensory and task-dependent variables, and these “mixed representations” are suggested to be important for perception, learning, and plasticity ...

Subcortical circuits mediate communication between primary sensory cortical areas in mice
Nature Communications, 2021 In the primary auditory cortex, visual or tactile stimuli can modulate acoustically-driven activity. Here, the authors show that circuits linking the primary somatosensory cortex to both the auditory midbrain and thalamus allow tactile inputs to modulate

Functional organization of the mammalian auditory midbrain. [PDF]
J Physiol Sci, 2015 The inferior colliculus (IC) is a critical nexus between the auditory brainstem and the forebrain. Parallel auditory pathways that emerge from the brainstem are integrated in the IC. In this integration, de-novo auditory information processed as local and ascending inputs converge via the complex neural circuit of the IC.

Neuromyelitis optica spectrum disorder with deafness and an extensive brainstem lesion
Heliyon, 2021 A 49-year-old woman developed vomiting, hiccups, double vision, and bilateral ptosis, after which tinnitus and deafness appeared. Head magnetic resonance imaging (MRI) showed a brainstem lesion focused on the midbrain and pons.

Representation of early sensory experience in the adult auditory midbrain: implications for vocal learning. [PDF]
PLoS ONE, 2013 Vocal learning in songbirds and humans occurs by imitation of adult vocalizations. In both groups, vocal learning includes a perceptual phase during which juveniles birds and infants memorize adult vocalizations.

Multiple Nonauditory Cortical Regions Innervate the Auditory Midbrain. [PDF]
J Neurosci, 2019 ABSTRACT Our perceptual experience of sound depends on the integration of multiple sensory and cognitive domains, but the networks sub-serving this integration are unclear. There are connections linking different cortical domains, however we do not know if there are also connections between multiple cortical domains and subcortical ...

An Overrepresentation of High Frequencies in the Mouse Inferior Colliculus Supports the Processing of Ultrasonic Vocalizations. [PDF]
PLoS ONE, 2015 Mice are of paramount importance in biomedical research and their vocalizations are a subject of interest for researchers across a wide range of health-related disciplines due to their increasingly important value as a phenotyping tool in models of ...

Frontiers in Neuroanatomy, 2017 The auditory system contains a diverse array of interconnected anatomical structures that mediate the perception of sound. The cochlear nucleus of the hindbrain serves as the initial site of convergence for auditory stimuli, while the inferior colliculus

Efficient Encoding of Vocalizations in the Auditory Midbrain [PDF]
The Journal of Neuroscience, 2010 An important question in sensory neuroscience is what coding strategies and mechanisms are used by the brain to detect and discriminate among behaviorally relevant stimuli. There is evidence that sensory systems migrate from a distributed and redundant encoding strategy at the periphery to a more heterogeneous encoding in cortical structures.
