The Cognitive Aging and Auditory Neuroscience Lab (CAANLab) is equipped to conduct perceptual and cognitive research while monitoring brain activity using electroencephalography (EEG).  We have a BioSemi EEG system capable of recording from up to 128 electrodes. This EEG system can also record the auditory brainstem response (ABR) or frequency following response (FFR). The EEG system is housed in a double-walled, magnetically shielded soundproof booth. Brain activity can be modulated using a NeuroConn transcranial current stimulator. An auditory workstation that includes a Tucker-Davis real-time processor, and an Interacoustics audiometer can present stimuli to participants in the soundproof booth via insert earphones, over-the-ear headphones or free-field speakers. A digital piano can be used to study to impact of music training or to observe musical performance. A virtual-reality system can be used with any of the existing equipment to simulate naturalistic environments during research. There are multiple workstations in the lab that can be used for data analysis, experimental design, and stimulus creation.
