Amusia and its electrophysiological correlates in neurofibromatosis type 1.

Introduction: Auditory processing deficits are common in people with neurofibromatosis type 1 (NF1) and they often report difficulties in musical performance.

Objective: We investigated whether NF1 could be associated with amusia as well as with some impairment of primary auditory cortex activity.

Methods: Eighteen people with NF1 and 22 healthy volunteers, matched for age, sex and educational level, were evaluated with the Montreal Battery Evaluation of Amusia - short version.

Synesthesia and music perception.

The present review examined the cross-modal association of sensations and their relationship to musical perception. Initially, the study focuses on synesthesia, its definition, incidence, forms, and genetic and developmental factors. The theories of the neural basis of synesthesia were also addressed by comparing theories emphasizing the anatomical aspect against others reinforcing the importance of physiological processes.
