Research Interest
Computational neuroscience, in particular for efficient sensory processing.
While advanced techniques have enabled us to observe a lot of neural activities, understanding the obtained data is still quite preliminary. How can we interpret them? Are there any underlying coding principles?
Recent studies on the primate visual system have been suggesting that the neural system's coding scheme nearly optimally adapts, both innately and in learning process, to natural stimuli or environment. I am interested in to what extent the hypothesis can be applied to, or is general across, various neural systems. Here are some of the current topics:
- Coding strategy in sensory processing
- Sparse, topographic coding in the auditory system
- Self-organisation of tactile coding in the barrel cortex
- Manifold untangling as a general approach for sensory perception
