[Research Areas]
◆ Decision making Decision making in a dynamic environment consists of multiple underlying processes such as representing values of potential choices, making choices based on these values, and updating the values based on the outcome of a choice. We investigate how these processes are implemented in the fronto-basal ganglia loop. We also investigate how multiple decision making systems (trial-and-error-based vs. deliberate control system) interact to yield a final action selection. To this end, we examine neuronal ensemble activity and manipulate neural activity in rodents, because they allow largesize neuronal ensemble recordings, use of genetically-modified animals, and relatively easy application of optogenetic techniques on top of that the nervous system is much simpler than that of the primate. We also conduct theoretical studies of reinforcement learning and neural network modeling.
◆ Event memory One of the central issues in cognitive neuroscience is to understand the neural basis of event memory. Although it is well known that the hippocampus plays a crucial role in encoding event memory, its underlying neural mechanisms remain unclear despite a long history of intensive investigations. We investigate how different types of information are integrated in the hippocampus during the formation of event memory (‘what happened’ ‘where’ and ‘when’) by conducting behavioral and neurophysiological experiments in rats. We also use genetically-engineered mice with specific disruptions in distinct sub-regions of the hippocampus (dentate gyrus, CA3 and CA1) to investigate functional roles played by each hippocampal sub-region in encoding event memory.
◆ Interval timing Time and space are fundamental dimensions for all living organisms. The ability to anticipate the timing of predictable events is critical for survival in many animal species including humans. In particular, time interval estimation in the range of a few seconds (interval timing) is involved in numerous behavioral processes. However, it is unknown how interval timing-related functions are implemented in the brain in large part because of the paucity of physiological studies. In order to investigate how the brain keeps track of the elapse of time, we record and analyze neuronal activity in different brain structures as rodents perform various time interval discrimination tasks.

How do we perceive the world? Inputs from the external world, i.e., sensory stimuli, need to be actively processed in the brain to be transformed into a "percept". Sensory processing (computation of sensory stimuli in the brain) is the gateway to sensory perception, and efficient sensory processing is required for the perceptual behavior of the animal. Switching from a drowsy, inattentive behavioral state to an aroused, attentive state is crucial for the effective perception of relevant sensory stimuli and execution of cognitively demanding tasks. How do our brain circuits execute this amazing function? We answer this question by studying the following topics in the mouse animal model:
- Modality-specific sensory processing
- Selective attention and modulation of perception
- Multisensory integration and cross-modal binding
- Perceptual decision and sensorimotor transformation
- Social perception
Our research aims to unravel brain circuits that are important for selective attention, multisensory integration, and behavioral decision, which are critical for cognitive and perceptual behaviors. Insights from our study should be broadly applicable to the treatment of psychiatric disorders including attention deficit disorder, autism, and schizophrenia.
