Without a clock, we are capable of timing our daily schedule or even keeping track of the seconds of our lives to synchronize movements to the sensory stimuli around us. But how do we do that? Not much is known about the function of specific brain areas implicated in timing and therefore, I am further exploring the roles of the cerebellum and basal ganglia in explicit and implicit sub-second rhythmic timing by working with patients with Parkinson' s disease.

Brain is a multi-gear oscillatory machine: different modes of cognitive process summon different activation patterns across neural ensembles near and far. In my research, I seek to answer how brain's oscillatory structure enables our integrated cognition by investigating its role in transmission of sensory information, spatial and temporal perception, and storage of memory traces. EEG, tACS and fMRI are the main methodologies I use to answer this question.

In the environment, there are a lot of visual or auditory stimuli and the characteristics of these stimuli gets processed in our brain. Sometimes, these have temporal information, and we can process the temporal information embedded in the stimuli. I am currently exploring how we can process multiple intervals simultaneously by using behavioral tasks since I am interested in the properties of neural system for interval processing.

Wei Chen

Doctoral Student

How do we understand what is a “goal”, a “method” or “time”? I am interested in exploring how the neural representation of semantic, verbal and sensory information connects to the understanding of a concept in our brain. Is it just clusters of information, how are they organized, and finally, can we reproduce it in a silicon chip?

Master's Student

We receive various sensory information through sensory organs and behave through processing them in the brain. However, there is no specific sensory organ for the perception of elapsed time. Considering the time perception may be deeply related to multisensory information integration including the somatosensory system, I’m planning to conduct research using psychophysical methods and virtual reality devices.

Syogo Sugiyama

Master's Student

A human brain is a sophisticated calculator which can process overwhelming amount of information, but it sometimes makes mistakes such as optical illusion. I am interested in this functional relationships between an objective fact and a subjective perception, so I study psychology and neuroscience. Now I am focusing on the ability of brains to integrate a lot of information iuput from various modalities like time perception and sense of agency, and trying to unveil the nature of human brains.

Master's Student

In the subjective world of mine, my consciousness exists, whereas I cannot say for sure yours exists, which makes “me” unique and special to me. Many research findings have also supported the claim that humans’ representation of the self is “special” and realized by systems that are distinct from those used for more general purposes. I seek to study neural underpinnings and evolutionary history of the human brain’s ability to distinguish self from others through behavioral experiments and functional neuroimaging techniques.

Hana Hinohara

Master's Student

“Time flies while you are having fun.” Our time perception depends on the environment. I’m interested in the situation which influences the time perception and the brain activity while such changes happens. I’m planning to investigate by using behavioral tasks and stimulators.

How VR-condition affects our cognition? For example, a research reports that time is felt to pass more quickly while playing a VR-game. It is said that our internal rhythm is related to such a phenomenon. However, there is room for further investigation. I am now working on creating stimuli for VR-condition with Unity. I want to research time-perception in VR-condition, by using stimuli I made.

Just as you feel the same hour longer or shorter, Perception can change depending on the environment, and vary from person to person. Even so, there is some consistency that enable everyday communication, and some generalizations are possible. I am interested in such aspects of perception and would like to learn more about how it works through research.
