Magnetoencephalography (MEG), a non-invasive neural imaging technique, is a perfect match for studying auditory processing. It is silent, has millisecond time resolution, and is sensitive to auditory cortical regions.
Center for Comparative and Evolutionary Biology of Hearing
Welcome to C-CEBH
Welcome to the web site of the Center for Comparative and Evolutionary Biology of Hearing (C-CEBH). C-CEBH is a multi-department and multi-college program that includes 13 core faculty and over 115 undergraduate and graduate students, postdocs, and research associates.
C-CEBH is founded on the principle that insights gained from studying different species, both vertebrate and invertebrate, can often help in understanding human hearing, in finding new cures for deafness and hearing disorders, in designing robotic devices, and in assessing the effects of noise on communication. As examples of the work done in C-CEBH, faculty in the Hearing and Speech department are studying how hearing loss in the elderly affects speech understanding, how cochlear implants can be improved, and hearing guides speech and language development in young children. Faculty in Electrical and Computer Engineering and in Linguistics are studying how complex sounds such as speech are represented in the auditory cortex. Faculty in Biology and in Psychology are studying how non-human organisms localize sound, learn vocalizations, navigate through their environment using acoustic cues, how noisy environments affect the health and well being of both animals and humans, and how hair cell regeneration in the ears of birds and fish help these animals recover from hearing loss.
C-CEBH is directly funded by both an institutional training grant (T-32), a core center grant (P-30) from the National Institute of Deafness and Other Communication Disorders (NIDCD) , and from funds provided by the University of Maryland. In addition, faculty in C-CEBH also receive research funding from NIH, NSF, and many other federal agencies.
In addition to UMD faculty from five departments, C-CEBH includes many intramural faculty from the NIDCD (one of the National Institutes of Health, NIH) many of whom are adjunct UM faculty and collaborate with C-CEBH investigators in research and student training. In addition, C-CEBH collaborates with researchers from the Walter-Reed Army Medical Center, and the National Center for Rehabilitative Auditory Research in Portland, Oregon. There are also international research and teaching collaborations in Germany, Denmark, China and several other countries. These close collaborations provide special opportunities for bringing additional expertise, skills and facilities to collaborative research questions especially in the areas of molecular genetics, developmental biology, and brain imaging. Together, the breadth of research questions addressed by faculty and students at C-CEBH and their collaborators is unparalleled.
