Vocal pitch is used as an important communicative device by humans, as
found in the melodic dimension of both speech and song. Vocal pitch is
determined by the degree of tension in the vocal folds of the larynx,
which itself is influenced by complex and non-linear interactions among
the laryngeal muscles. The relationship between these muscles and vocal
pitch has been described by a mathematical model in the form of a set of
“control rules”. We searched for the biological implementation of these
control rules in the larynx motor cortex (LMC) of the human brain. We
scanned choral singers with functional magnetic resonance imaging as they
produced discrete pitches at four different levels across their vocal
range. While the locations of the larynx motor activations varied across
singers, the activation peaks for the four pitch-levels were highly
consistent within each individual singer. This result was corroborated
using multivoxel pattern analysis, which demonstrated an absence of
patterned activations differentiating any pairing of pitch-levels. The
complex and non-linear relationships between the multiple laryngeal
muscles that control vocal pitch may obscure the neural encoding of vocal
pitch in the brain.
