Function Description

My research interest is to understand dynamics of neural activity and eye-movements related to perceptual process of visual information. Especially, I am interested in perceptual switching phenomenon in ambiguoous figures.

CV

I was born in Sendai, Japan, in January 7, 1973.

I received the B.E., M.E., and Ph.D. degrees in electronic engineering from Tohoku University, Sendai, Japan, in 1996, 1998, and 2001, respectively.

From April 2001 to March 2002, I was a Research Associate in the Department of Electronic Engineering, School of Engineering, Tohoku University. My research topic was to estimate sensory information from peripheral nerve activity for a neural prothesis.

Since April 2002, I have been a Research Scientist in RIKEN Brain Science Institute (BSI).

My current research interest is to understand dynamics of visual information processing in human. I am especially interested in the spatiotemporal property of spontaneous brain activity, that is often considered to be "noise", and its function in perceptual process. I analyze electroencephalogram (EEG), brain activity recorded as electrical signal, related to perceptual switching in an ambiguous figure with our proposed trial-per-trial ERP analysis.

I will move to Laboratory dor Dynamics of Emergent Intelligence in April, 2007.

I am a member of Japanese Society for Medical and Biological Engineering (JSMBE), The Institute of Electronics, Information and Communication Engineers (IEICE), Society for Neuroscience (SfN), The Japan Neuroscience Society (JNS), The society of Instrument and Control Engineers (SICE).
