Researchers have created the first 3D map of the hearing nerve showing where the various sound frequencies are captured. Using what is known as synchrotron X-ray imaging, they were able to trace the ...

Phase-contrast imaging data showing the ear membrane and auditory nerve in the cochlea. The octave bands are shown in different colours. Humans can perceive frequencies from 20 Hz (the top of the coil ...

The brain filters what we hear. It can do this in part because particular groups of neurons react to specific frequencies of sound. Neurobiologists have now created a "frequency map" for numerous ...

Researchers at Uppsala University have created the first 3D map of the hearing nerve showing where the various sound frequencies are captured. Using what is known as synchrotron X-ray imaging, they ...
