RECENT RESEARCH TOPICS
Vincent Van Meir applies different MRI techniques on songbirds.
Songbirds evolved the remarkable feature of vocal communication, which is very familiar to human speech, language and even music and proofed to be excellent models for brain plasticity. Extensive neuroethological research done in songbirds has yielded significant insights into how a brain perceives species-specific sounds, generates them and does so within different social contexts and developmental stages of life. Manganese Enhanced MRI allows to evaluate functional changes in circuits of the song control system using repeated injections of MnCl2 in HVC. The recent successful application of BOLD fMRI with acoustic stimuli, spanning both a broad range of sensory motor complexity and different levels of cognitive processing, provides a potential path for bridging the gap between the abstract experimental tasks applied in rats and mice and the real-world behaviour of small laboratory animals, even under anaesthetized conditions. Introduction of fMRI in songbirds may establish a firm link between human neuroimaging studies done on auditory, music and language processing and the large body of neuroethological research performed in songbirds over the last halve a century.
