We propose an ionic current model of bipolar cells based on the published experimental data. Five types of ionic currents identified in bipolar cell bodies, Ih, IKv, IA, ICa and IK(Ca) were described by a mathematical formulation similar to the Hodgkin and Huxley (Journal of Physiology, 117, 500-544, 1952) equations. The model parameters were estimated from(More)
A model of the L-type horizontal cell layer in the retina was constructed in terms of the soma, axon terminal and gap junction to understand its spatiotemporal properties. The soma and axon terminals were expressed by the Hodgkin-Huxley-type equations based on the relevant ionic currents. The cell layer was simulated by connecting each L-type horizontal(More)
The effects of the GABAergic pathway on the dynamic range of the light response of cone-driven horizontal cells (HCs) in the carp retina were investigated using conventional intracellular recordings and computer simulations. The amplitude of the HC responses to repetitive test flashes was altered by background illumination in control Ringer's solution, but(More)
In this paper we introduce Oto-Shigure, an umbrella-shaped sound generator for musical expression. Attention of the music computing community hasn't been focusing on sound output but sound input. However, we argue that in order to make highly expressive sounds, it is significant to increase methods for sound output. Therefore, we developed the new(More)
This paper proposes a Situation Design that designs not only the experience of behavior itself, but also the experience of the environment around the behavior. The research question of this paper is how to motivate children to paint. To find answers, we implemented an iPhone application. The app we came up with was The World Is Canvas; using it, one will be(More)
A series of simulations were carried out to reproduce unsteady combustion around the hypervelocity cylindrical projectiles. A simplified two-step chemical reaction model was used to handle the reactions behind the bow shock. The simulations were examined with various parameters, such as projectile speed, initial pressure, and projectile diameter, and the(More)
This paper focuses on the creativity of painting in artistic creativities and aims to increase children's motivation in painting. This research assumes that fun through physical interactions increases the motivation for children to paint. We developed two approaches and implemented an iPhone application "The World is Canvas". This application allows users(More)
