TL;DR
Results indicate similar MMN in amusics and controls, even for an eighth of a tone change, revealing that the amusic brain can process small pitch changes at a pre‐attentive level and related to a problem of perceptual awareness.
Abstract
Congenital amusia is a lifelong disorder affecting the processing of pitch. This pitch deficit can be traced down to abnormal brain responses elicited by pitch changes smaller than a semitone in conditions requiring attention. Here, we use the mismatch negativity (MMN) to investigate pre-attentive pitch change detection in 10 amusics and eight matched controls. Results indicate similar MMN in amusics and controls, even for an eighth of a tone change, revealing that the amusic brain can process small pitch changes at a pre-attentive level. Thus, the pitch deficit in congenital amusia may be related to a problem of perceptual awareness.

The mismatch negativity (MMN) enables one to establish the brain processes underlying the initiation of attention switch to, conscious perception of, sound change in an unattended stimulus stream.

The selection of instructions for subjects, the recording technique, the elimination of a few single trials significantly contaminated by eye movements, and the use of a correction procedure for ocular artifacts with calculable reliability and validity resulted in a set of data, in which 94% of the single trials were suitable for further analysis.

The Montreal Battery of Evaluation of Amusia (MBEA) is proposed to use because it is arguably the best tool currently available and theoretically motivated and satisfies important psychometric properties.

Evidence that the disorder stems from a deficit in fine-grained pitch perception is presented, which points to the presence of a congenital neural anomaly that selectively impairs pitch processing.

The pitch deficits identified are able to account for the music perception difficulties in this disorder, and implicate deficient cortical processing.
BrainThe amusic brain: in tune, out of key, and unaware
225 Citations2009Isabelle Peretz, Elvira Brattico +2 more
It is suggested that the amusic brain is equipped with the essential neural circuitry to perceive fine-grained pitch differences, but the neural pitch representation cannot make contact with musical pitch knowledge along the auditory-frontal neural pathway.

These data demonstrate a role for central memory T cells in natural malarial immunity and support current vaccination strategies aimed at inducing durable protective T cell responses against the TRAP antigen and suggest that CD4+ CD25high T cells may negatively affect naturally acquired malarial Immunity.

Novel electrophysiological evidence is presented that this disorder can be traced down to a right‐lateralized N2‐P3 response elicited by pitch changes, which may serve as a marker of an anomaly in music acquisition.

100 Citations2001Isabelle Peretz
There are numerous behavioral indications that music-specific networks are isolable in the brain, and the discovery that music may have systematic associations with other cognitive domains or variable brain organization across individuals supports the view that music is a cultural artifact.

A neural correlate of patients' unawareness of melodic distortions is identified: deviant notes modulated long-latency auditory evoked potentials and elicited a mismatch negativity in controls but not in affected subjects, suggesting that, as in blindsight, TD subjects process stimuli that they cannot consciously perceive.
