Tonotopy in human auditory cortex examined with functional magnetic resonance imaging
Human Brain Mapping, 1997 Tonotopic organization within the human auditory cortex was investigated with functional magnetic resonance imaging (fMRI) using the blood oxygenation level-dependent (BOLD) contrast mechanism. Single-frequency pulsed tones were alternated with no-tone conditions to elicit stimulus-specific functional activity.

Tonotopic organization in the depth of human inferior colliculus
Frontiers in Human Neuroscience, 2013 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 ...

The Journal of Physiology, Volume 603, Issue 22, Page 7049-7070, November 15, 2025.Abstract figure legend Knollenorgans of mormyrid fish transmit high‐frequency electrical signals. Mormyrid electric fish (top) have Knollenorgans (electroreceptors) on their bodies (red and blue dots) that detect electrical stimuli (middle, left) through an electrical tuning mechanism.

Stiffness and tension gradients of the hair cell’s tip-link complex in the mammalian cochlea
eLife, 2019 Sound analysis by the cochlea relies on frequency tuning of mechanosensory hair cells along a tonotopic axis. To clarify the underlying biophysical mechanism, we have investigated the micromechanical properties of the hair cell’s mechanoreceptive hair ...

Questions and controversies surrounding the perception and neural coding of pitch
Frontiers in Neuroscience, 2023 Pitch is a fundamental aspect of auditory perception that plays an important role in our ability to understand speech, appreciate music, and attend to one sound while ignoring others.

Mutation of Npr2 leads to blurred tonotopic organization of central auditory circuits in mice. [PDF]
PLoS Genetics, 2014 Tonotopy is a fundamental organizational feature of the auditory system. Sounds are encoded by the spatial and temporal patterns of electrical activity in spiral ganglion neurons (SGNs) and are transmitted via tonotopically ordered processes from the ...

Neuronal activity underlying vocal production in bats
Annals of the New York Academy of Sciences, Volume 1550, Issue 1, Page 37-54, August 2025.Bats are known for their highly evolved echolocation and social vocalizations. They have been well studied in terms of auditory processing, but their neural circuits for vocal production are far less understood. This review highlights recent progress in mapping neural activity linked to vocalization in bats.
