Determinative Factors in Human Tonotopy: Tentative Analysis

Acta Oto-Laryngologica, 1986
Two main parameters of stimulation were checked as an attempt to investigate the limits of the tonotopic organization in the human auditory cortex. Auditory Evoked magnetic Field (AEF) experiments from a dozen normal subjects are reported. Five of them clearly showed tonotopic AEF responses to long tone bursts stimuli, which disappeared when equivalent

Cochlear development, cellular patterning and tonotopy

Current Opinion in Physiology, 2020
Mammalian audition is mediated through the organ of Corti (OC), a rigorously patterned mosaic of mechanosensitive hair cells and associated supporting cells arrayed along the long (coiled) axis of the cochlea. Incoming sounds stimulate hair cells along the spiral based on a frequency-place, or tonotopic, code. Using the temporal bones of human cadavers,

Development of tonotopy in the auditory periphery

Hearing Research, 2011
Acoustic frequency analysis plays an essential role in sound perception, communication and behavior. The auditory systems of most vertebrates that perceive sounds in air are organized based on the separation of complex sounds into component frequencies.

Alterations in tonotopy and auditory cerebral asymmetry in schizophrenia

Biological Psychiatry, 2002
Deficits in basic auditory perception have been described in schizophrenia. Previous electrophysiologic imaging research has documented a structure-function disassociation in the auditory system in schizophrenia. This study examines whether the most fundamental level of auditory cortical organization, tonotopy, is altered in schizophrenia.The tonotopic

Mismatch of structural and functional tonotopy for natural sounds in the auditory midbrain

Neuroscience, 2014
Neurons in the auditory system are spatially organized in their responses to pure tones, and this tonotopy is expected to predict neuronal responses to more complex sounds such as vocalizations. We presented vocalizations with low-, medium- and high-frequency content to determine if selectivity of neurons in the inferior colliculus (IC) of mice ...

Mapping Tonotopy in Human Auditory Cortex

2013
Tonotopy is arguably the most prominent organizational principle in the auditory pathway. Nevertheless, the layout of tonotopic maps in humans is still debated. We present neuroimaging data that robustly identify multiple tonotopic maps in the bilateral auditory cortex.

Tracing tonotopy in teleosts.

The Journal of the Acoustical Society of America, 2011
It is not known whether the auditory hair cells of fishes possess a tonotopic organization in the saccule. To investigate this question, we exposed groups of six goldfish (Carassius auratus) to one of four tones (100, 800, 2000, and 4000 Hz) at 176 dB re 1 μPa for 48 h.

Cochlear and CNS tonotopy: Normal physiological shifts in the mustached bat

Hearing Research, 1991
The ear of the mustached bat (Pteronotus parnellii) shows marked cochlear resonance near 60 kHz and many sharply tuned neurons throughout the brain have best frequencies (BF) near the cochlear resonance frequency (CRF). Controlled changes in the normal physiological range of body temperature (approx 37-42 degrees C) were used to change the CRF and to ...
