Investigation on the pleasantness of music perception in monolateral and bilateral cochlear implant users by using neuroelectrical source imaging: a pilot study.

There is a debate in the specialized literature about the quality of fruition of music for patients that received a cochlear implant. Interestingly, very few studies have investigated the hypothesis that patients that use a bilateral cochlear implant could perceive the music in a more pleasant way as compared to unilaterally implanted patients. Previous observations in healthy subjects have indicated that variations of particular EEG rhythms correlated with the pleasantness of the perceived music. The aim of the present pilot study is then to apply the state of the art neuroelectrical imaging and the analysis of cortical representation of EEG rhythms to monitor the perceived pleasantness during the observation of a simple videoclip in one patient with a unilateral cochlear implant and in one receiving a bilateral cochlear implant. Results of this pilot study showed that on the base of such previously validated EEG rhythms, the fruition of music and video, in terms of pleasantness, is statistically higher in the bilaterally implanted patient when compared to the monolateral implanted patient.
