Which of the following statements best explains how some neurons in the primary auditory cortex people recognize and distinguish between the sounds they hear?
a. some neurons prefer a certain frequency, such as high sounds.
b.
some neurons combine information from the specialist cells.
c.
some neurons categorize sounds into their specific frequency.
d.
some neurons process specific types of sounds, such as voices.

The right answer is C. Some neurons categorize sounds into their specific frequency.

The animal vocalizations and the human language vary widely between the individuals and even in each individual there exist variations, voluntary and involuntary. Although the perception of sound messages requires an analysis of the frequencies composing a complex sound, what is even more important is the analysis of the sound spectrum.

If we keep the spectrum containing the entire profile of the sound waves of a complex sound (wave envelope), even omitting specific frequencies, it is possible to preserve a good hearing and understanding of phonemes.

the organisms are not adapted to live in some communities or habitats.
