COCHLEAR INC.

With the important multinational in the area of cochlear implant, BrainSigns has been involved with Cochlear inc. in a series of important research projects that have leaded to an impressive series of scientific publications on international journals.

The importance to have a bilateral cochlear implant for enjoing music 

The first line of research made with Cochlear since 2011-2013 aimed to evaluate if the patients with bilateral cochlear implants perceived the music with more pleasure (emotionally) when compared with themselves when they had just one monolateral cochlear implant.

The results pointed in the direction that patients with bilateral cochlear implants enjoy more music listening than patients with a monolateral implant. This results holds for children as well as for adults, as verified by two independent studies performed with the different hospitals: Bambin Gesù Pediatric Hospital in Rome and Monaldi in Naples.

The importance to have a cochlear implant for improve the quality of learning (workload evaluation)

A recent line of research actually performing with Cochlear since 2015 and up to 2017 is aimed to evaluate if the patients with bilateral cochlear implants perceived the speech information with less cognitive effort when compared with themselves when they had just one monolateral cochlear implant.

In fact, the major cerebral workload for monolateral cochlear implant patients during speech listening could be reflected in a major insurgence of mental fatigue and then difficulties to learn when compared to their bilateral counterpart. This hypothesis could be important for the verification of possible delay in learning for children during elementary school attendance.

Investigation are running on two separate projects with children (Bambin Gesù, Rome) and adults (IRCCS S. Raffale Milano, and Martini hospital in Turin).
