Cognitive Neuroscience

My research is in the field of cognitive neuroscience and focuses on the brain processes that mediate perception and cognition of auditory patterns and events, specifically short-term memory and selective attention. I use a combination of neuroimaging techniques (e.g., ERPs, PET, and fMRI) to investigate which, and how, different brain areas work together when participants' attention is directed to a particular sound identity and/or sound location in the auditory field. The hypothesis is that the auditory system provides the listener with the identity of the event as well as its location, i.e. the what and the where, and that these two types of information are provided by different areas of the brain. I am also interested in the neural and psychological mechanisms that underlie auditory scene analysis and how these mechanisms are influenced by the aging process.

Current Activities

We are currently conducting several experiments that focus on the neural correlates of auditory scene analysis using either EEG, MEG and/or fMRI.
For instance, there are projects on:
1. Age-related difference in auditory cortical activity underlying concurrent sound perception.
2. Age-related difference in identifying and localizing auditory object using fMRI.
2. Roel of musical expertise on auditory scene analysis.
