I study the neural causes of consciousness in humans, combining psychophysics, non-invasive brain imaging and manipulative techniques.

My lab is developing and applying new techniques such as neurofeedback and electric current stimulation, to understand the neural causes of visual awareness. Based on our previous research, we think that critical components for visual awareness could include not just activity in early visual areas, but also recurrent networks possibly working at alpha/beta frequencies and/or activity in frontal brain regions. Our approach to test these ideas is based on manipulative/interventional techniques such as decoded neurofeedback (using either fMRI or MEG) and transcranial alternating current stimulations (tACS). For example, we have recently found promising results in creating orientation-specific color perception using fMRI decoded neurofeedback.

My lab also probes other aspects of visual awareness, including the neural mechanisms of feature integration across modalities – known as the binding problem. More recently, we’ve begun utilising high resolution (7T fMRI) imaging methods to look for new visual maps in the brain.

We’re also interested in applications development. For example, neurofeedback techniques may have clinical value in improving visual awareness in blindsight and visual neglect patients. In addition, we are exploring the possibility of developing new user-interfaces that enhance important but otherwise ‘sub-conscious’ visual information.

I accept PhD students via the Graduate School of Frontier Sciences, Osaka University, and Japan Society for Promotion of Science (JSPS) post-doctoral fellows are also highly welcomed.
