The relative pitch of harmonic complex sounds, such as instrumental sounds, may be perceived by decoding either the fundamental pitch (f0) or the spectral pitch (fSP) of the stimuli. We classified a large cohort of 420 subjects including symphony orchestra musicians to be either f0 or fSP listeners, depending on the dominant perceptual mode. In a subgroup of 87 subjects, MRI (magnetic resonance imaging) and magnetoencephalography studies demonstrated a strong neural basis for both types of… 

Structural, Functional, and Perceptual Differences in Heschl's Gyrus and Musical Instrument Preference

There is a strong correlation between pitch perception preference and asymmetry of brain structure and function in the pitch‐sensitive lateral areas of Heschl's gyrus (HG), irrespective of musical ability.

Auditory and frontal anatomic correlates of pitch discrimination in musicians, non-musicians, and children without musical training.

The results suggest that the relationship between pitch discrimination and theVolume of auditory regions is innately established early in life, and that musical training modulates the volume of the IFG, probably improving audio-motor connectivity.

Absolute Pitch—Functional Evidence of Speech-Relevant Auditory Acuity

The results suggest that the neural underpinnings of pitch processing expertise exercise a strong influence on propositional speech perception (sentence meaning) by systematically varying the lexical and/or prosodic information of speech stimuli.

Increased volume and function of right auditory cortex as a marker for absolute pitch.

The right HG is proposed as an anatomical marker of AP and it is suggested that a right-hemispheric network mediates AP "perception," whereas pitch "labeling" takes place in the left hemisphere.

Subcortical and cortical correlates of pitch discrimination

Two levels of neuroplasticity in musicians are suggested, whereby training-dependent changes in pitch processing arise at the collicular level and are preserved and further enhanced in the right auditory cortex.

Experiments on the perception of complex tones with a missing fundamental (F0) show that listeners can be categorized into two

Experiments on the perception of complex tones with a missing fundamental (F0) show that listeners can be categorized into two groups, depending on what pitch they perceive to be more salient: the

Mesoscopic dynamics of pitch processing in human auditory cortex

A novel theory is proposed describing how subcortical representations of pitch-related information are integrated in cortex and how this integratory process gives rise to the dynamics observed in magnetoencephalographic (MEG) experimental recordings.

Resting state functional connectivity of the ventral auditory pathway in musicians with absolute pitch

Investigating resting state functional connectivity using functional magnetic resonance imaging (fMRI) from musicians with varying degrees of AP found greater RSFC between the right PP and bilateral anteroventral auditory cortices in musicians with AP, which supports conjecture on the critical role of the ventral pathway in AP recognition.

Dual-Pitch Processing Mechanisms in Primate Auditory Cortex

This work investigates how cues derived from the temporal envelope and spectrum of an acoustic signal are used for pitch extraction in the common marmoset (Callithrix jacchus), a vocal primate species, by measuring pitch discrimination behaviorally and examining pitch-selective neuronal responses in auditory cortex.

This work addresses the brain basis for the analysis of pitch and pitch patterns required for normal musical perception and suggests that there may be a “pitch center” in the lateral part of Heschl's gyrus, adjacent to the primary auditory area.

Morphology of Heschl's gyrus reflects enhanced activation in the auditory cortex of musicians

Results indicate that both the morphology and neurophysiology of Heschl's gyrus have an essential impact on musical aptitude.

A Neural Representation of Pitch Salience in Nonprimary Human Auditory Cortex Revealed with Functional Magnetic Resonance Imaging

Functional magnetic resonance imaging was used to measure activation in response to harmonic tone complexes whose temporal regularity was identical, but whose pitch salience differed, across conditions, contributing to converging evidence that anterior areas of nonprimary auditory cortex play an important role in processing pitch.

Functional specificity in the right human auditory cortex for perceiving pitch direction.

Adaptive psychophysical procedures were used to determine auditory perceptual thresholds in 14 neurologically normal subjects and in 31 patients who had undergone surgical resection from either the right or left temporal lobe for the relief of intractable epilepsy to support a specialization of function linked to right auditory cortical areas for the processing of pitch direction.

Spectral and temporal processing in human auditory cortex.

Hierarchical processing suggests that spectrally and temporally complex stimuli will evoke more activation than do simple stimuli, particularly in non-primary auditory fields. This hypothesis was

Analysis of temporal structure in sound by the human brain

This work used functional imaging and a 'delay-and-add' noise, which activates all frequency regions uniformly, like noise, but which nevertheless produces strong pitch perceptions and tuneful melodies, to locate the mechanism for the detection of temporal regularity in humans.

Increased auditory cortical representation in musicians

The results, when interpreted with evidence for modified somatosensory representations of the fingering digits in skilled violinists, suggest that use-dependent functional reorganization extends across the sensory cortices to reflect the pattern of sensory input processed by the subject during development of musical skill.
