The image you are able to get of cortex via the MRI scanner reveals what the reviewer is listening to.
DRCMR has just received a new 7 Tesla scanner, which is able to get even sharper images of what happens in the brain when we listen.

Until now, the Danish Research Centre for Magnetic Resonance (DRCMR) at Hvidovre Hospital has had a tradition of working primarily with the vision sense. However, interdisciplinary research projects, in collaboration with the new Oticon Centre of Excellence for Hearing and Speech Sciences (CHESS) DTU, are exploring the link between the auditory system and brain activities.

How does your brain react to many different sound sources at the same time? And why are some people able to focus on one particular sound and isolate it from the rest, while others find it almost impossible, also known as the Cocktail Party Problem.
A new research co-operation aim to answer these questions and are supported by the new audio visual laboratories at DTU, which is expected to be ready in December this year.

Postdoc at Hearing Systems and DRCMR Jens Hjortkjær is featured in an article in Hørelsen, the magazine for the Danish Association of Hard of Hearing.
