Developmental mechanism of functional maps in brain
Orientation map is a great interest among the cortical functional maps, but its developmental mechanism has been controversial. As a theoretical model, it was suggested that a moiré interference pattern between ON and OFF Retinal Ganglion Cell (RGC) mosaics can develop a quasi-periodic orientation map in visual cortex. Assuming the existence of a local interaction between neighboring RGCs, we simulate the development of interference pattern between ON and OFF RGC mosaics that can seed the consistent spatial periodicity in orientation map.

Visual perception and Computational modelling
When sensory system receives an ambiguous signal, human perception often switches between two or more possible interpretations. This perceptual phenomenon is called multistable perception and considered important since this phenomenon links the relationship between the stimulus and sensation of the brain. This perceptional switch is considered important to understand brain functions thus extensively studied, however the complete mechanism of multistable perception is still elusive. To investigate the various feature of multistable perception, we perform psychophysics experiment and simulate the computational model to explore the mechanism. This study will provide an insight into how brain makes a perceptual interpretation based on the external stimulus.

Network Properties & Network simulation
A neural network shows various computational function and activity feature, such as oscillation or synchrony, in different sub-region in brain. However the underlying mechanism of generating these function and feature are not yet clear. The main research interest is on configuring structural mechanism of various feature and function of network using computer simulation.

Memory allocation & Computational modeling​

Memory allocation is considered one of the key factors for efficient use of limited memory capacity. However, the effects of memory allocation and its mechanism is still elusive. Here, we perform psychophysical experiments and simulate computational models to investigate the various features of memory allocation.

Memory simulation using spike-timing-dependent plasticity (STDP)

Spike-timing-dependent plasticity (STDP) is considered critical to learning and memory. However, specific roles of diverse STDP profiles in memory formation still remain elusive. My research shows that the symmetry of learning rate profile in STDP is crucial to determining memory type, namely long-term and short-term.

Principles underlying information coding in brain

What are the commonality and difference among diverse intelligent systems? To understand intelligence, we should understand the brain. Our brain encodes information from external world by exploiting neurons and their connections. Understanding principle of information coding strategy in those networks gives deeper understanding of intelligent systems. I am dealing with this question along with recent experimental observation of functional maps in the visual cortex. Several topics that I’m interested in are i) information theoretical roles & implications of orthogonal & parallel relationships between functional maps in a brain, ii) explaining difference in functional maps among species, and iii) identifying general network topologies of visual & auditory systems.

Developmental mechanism of functional maps in the brain

Various functional maps are found in mammalian primary visual cortex. However maps other than orientation map has been far less studied compared to orientation map. Our research focused on the development of spatial frequency map in V1 and its relationship with orientation map.

 

Audio-Visual Perception and illusion
Our perceptual systems appropriately and flexibly integrate inputs from multiple sensory modalities. My research focuses on the perceptual effect of audio and visual crossmodal interaction.
