Complex behaviors are achieved by coordinated activities in a large network of neurons that integrate sensory, perceptual, motivational information with fine movement control. Nevertheless, understanding how the information is encoded, transmitted, and transformed throughout the neural network during diverse cognitive and sensorimotor processes, still remains one of the greatest challenges in neuroscience.

The final goal of the Systems Neuroscience group is to understand human cognition, memory, sensorimotor processing and behavior in collaboration with other groups. Principle investigators in the SN group study the brain circuits and functions in humans, primates and rodents.




The goal of our research is to understand how the human brain gives rise to perception and cognition. In order to gain a comprehensive understanding of the cognitive and neural mechanisms that underlie human mental processes, including perception, attention, and memory we combine techniques from neuroimaging (encoding and decoding), vision sciences, and cognitive psychology. This allows us to explore how the brain represents and processes a range of perceptual and cognitive information linking fMRI BOLD responses and psychophysical measures.





Humans are constantly interacting with the external environment by receiving sensory information through sensory organs, processing them, and reacting to them. This basic interaction is performed through a series of neural processes. We study the neural circuit mechanisms for the transformation and transmission of information across brain areas, and how cognition controls information flows.





Animals including human should utilize automatic and voluntary behaviors for survival. My short-term goal is to reveal the brain circuits for automatic and voluntary behavior and manipulate these. To find the whole circuits and their mechanisms, my lab is using various kinds of techniques including molecular biology, electrophysiology, genetics and MRI. I believe that new behavioral circuits will provide knowledge about the brain mechanisms and new treatment methods for brain disease patients.




We study neural mechanisms underlying auditory perception. One of our goals is to reveal circuit mechanisms that allow perception of meaningful sounds in noisy environments. It is known that humans and animals can do this, but circuit mechanisms that enable this remarkable ability remains unclear. We are also interested in understanding how this ability critical for social communication is affected in disease states as in partial hearing loss. We are tackling these questions using a combination of neurophysiological, anatomical, and behavioral approaches in rodents. Moreover, we are developing collaborative functional brain mapping projects using high field animal magnetic resonance imaging techniques.
