My research is focused on mechanisms underlying human visual dynamics and attention, and their relation to human consciousness.
Our research uses psychophysical techniques in combination with a number of human brain imaging methods, including fMRI, MEG and EEG. Over a series of experiments, we’ve shown that visual attention modulates specific neural activity in human visual cortex, even before stimulus onset. Furthermore, we’ve shown that the levels of such modulation is highly predictive of behavioral performance.
We’re also interested in applying such basic findings to support ambient intelligence. My lab has pioneered the use of real-time attention monitoring systems that enable us to predict humans’ internal states (e.g., attentional direction and/or readiness level) from brain imaging data. Using this system, it is possible to develop real-time applications in a number of new domains.

Noriko Yamagishi was awarded Ph.D. from Purdue University (Department of Psychological Sciences, Cognitive Psychology) in 1995. She was a postdoctoral fellow at University of California, San Diego (Department of Ophthalmology) from 1995 to 1996, and at Royal Holloway, University of London (Department of Psychology) from 1996 to 1997. She was a senior researcher at Advanced Telecommunications Research Institutes International from 1997 to 2013. She has joined the CiNeT as a senior researcher since 2013.
