Auditory neurons in humans far more sensitive to fine sound frequencies than most mammals

The human ear is exquisitely tuned to discern different sound frequencies, whether such tones are high or low, near or far. But the ability of our ears pales in comparison to the remarkable knack of single neurons in the brain to distinguish between the very subtlest of sound frequencies. Repor...

Sound Separated into Sound Frequencies

It has long remained a mystery how even in loud environments - like a factory with rattling machines, or a party with music and a cacophony of people// talking - we can hear the voice of our conversational partner. This showed that the brain chooses what to hear. Neurophysiologists still do not...
