Linking Topography to Tonotopy in the Mouse Auditory Thalamocortical Circuit [PDF]
The Journal of Neuroscience, 2011 The mouse sensory neocortex is reported to lack several hallmark features of topographic organization such as ocular dominance and orientation columns in primary visual cortex or fine-scale tonotopy in primary auditory cortex (AI). Here, we re-examined the question of auditory functional topography by aligning ultra-dense receptive

Organization of the Auditory Brainstem in a Lizard, Gekko gecko. II. Afferent and Efferent Projections of Nuclei of the Lateral Lemniscus and the Torus Semicircularis. [PDF]
J Comp NeurolWe used tract tracing and in vivo physiology to investigate auditory processing in the brainstem of the Tokay gecko. We found conserved patterns of connection in higher‐order auditory nuclei and an apparent lack of tonotopy at the level of the auditory midbrain.

Neuronal activity and tonotopy in the auditory system visualized by c-fos gene expression [PDF]
Brain Research, 1991 Responsiveness in the cochlear nucleus complex and inferior colliculus of the mouse to tonal stimulation is labelled via immunocytochemically stained Fos protein that is expressed by c-fos gene activation in excited neurons. The locations of Fos-positive neurons closely reproduce the tonotopic maps in the dorsal cochlear nucleus and inferior colliculus.

eLife, 2019 Hearing sensation relies on the mechano-electrical transducer (MET) channel of cochlear hair cells, in which transmembrane channel-like 1 (TMC1) and transmembrane channel-like 2 (TMC2) have been proposed to be the pore-forming subunits in mammals.

Mechanical network equivalence between the katydid and mammalian inner ears. [PDF]
PLoS Computational BiologyMammalian hearing operates on three basic steps: 1) sound capturing, 2) impedance conversion, and 3) frequency analysis. While these canonical steps are vital for acoustic communication and survival in mammals, they are not unique to them.

Structural and functional effects of acoustic exposure in goldfish: evidence for tonotopy in the teleost saccule [PDF]
BMC Neuroscience, 2011 Background Mammalian and avian auditory hair cells display tonotopic mapping of frequency along the length of the cochlea and basilar papilla. It is not known whether the auditory hair cells of fishes possess a similar tonotopic organization in the ...

Development of Tonotopy in the Inferior Colliculus II: 2‐DG Measurements in the Kitten [PDF]
European Journal of Neuroscience, 1994 AbstractThe development of size and tonotopy in the inferior colliculus of the kitten was studied using the [14C]2‐deoxyglucose technique and tone stimulation with 2 and 15 kHz at a maximum 110 dB sound pressure level. At 2 days of age, frequency‐specific labelling cannot be detected.
