Topological Maps and Brain Computations From Low to High
Frontiers in Systems Neuroscience, 2022 We first briefly summarize data from microelectrode studies on visual maps in non-human primates and other mammals, and characterize differences among the features of the approximately topological maps in the three main sensory modalities.

Developmental gene expression profiling along the tonotopic axis of the mouse cochlea. [PDF]
PLoS ONE, 2012 The mammalian cochlear duct is tonotopically organized such that the basal cochlea is tuned to high frequency sounds and the apical cochlea to low frequency sounds.

Thalamic input to auditory cortex is locally heterogeneous but globally tonotopic
eLife, 2017 Topographic representation of the receptor surface is a fundamental feature of sensory cortical organization. This is imparted by the thalamus, which relays information from the periphery to the cortex.

Investigating the Reliability of Population Receptive Field Size Estimates Using fMRI
Frontiers in Neuroscience, 2020 In functional MRI (fMRI), population receptive field (pRF) models allow a quantitative description of the response as a function of the features of the stimuli that are relevant for each voxel.

Lemniscal Corticothalamic Feedback in Auditory Scene Analysis
Frontiers in Neuroscience, 2021 Sound information is transmitted from the ear to central auditory stations of the brain via several nuclei. In addition to these ascending pathways there exist descending projections that can influence the information processing at each of these nuclei ...

Fractured tonotopy of functional neural clusters in mouse auditory cortex [PDF]
, 2016 AbstractThe degree of order versus randomness in mammalian cortical circuits has been the subject of much discussion. Previous reports showed that at a large scale there is smooth tonotopy in mouse auditory cortex, while at the single neuron level the representation is the traditional “salt and pepper” configuration attributed to rodent cortex. Here we

Frontiers in Neural Circuits, 2013 Descending projections from the cortex to subcortical structures are critical for auditory plasticity, including the ability for central neurons to adjust their frequency tuning to relevant and meaningful stimuli.

Synapse Maturation and Developmental Impairment in the Medial Nucleus of the Trapezoid Body
Frontiers in Integrative Neuroscience, 2022 Sound localization requires rapid interpretation of signal speed, intensity, and frequency. Precise neurotransmission of auditory signals relies on specialized auditory brainstem synapses including the calyx of Held, the large encapsulating input to ...

The topography of frequency and time representation in primate auditory cortices
eLife, 2015 Natural sounds can be characterised by their spectral content and temporal modulation, but how the brain is organized to analyse these two critical sound dimensions remains uncertain.
