The grid cells of the rat medial entorhinal cortex (MEC) show an increased firing frequency when the position of the animal correlates with multiple regions of the environment that are arranged in regular triangular grids. Here, we describe an artificial neural network based on a twisted torus topology, which allows for the generation of regular triangular(More)
The lobula giant movement detector (LGMD) system in the locust responds selectively to objects approaching the animal on a collision course. In earlier work we have presented a neural network model based on the LGMD system which shared this preference for approaching objects. We have extended this model in order to evaluate its responses in a real-world(More)
Ada is an entertainment exhibit that is able to interact with many people simultaneously, using a language of light and sound. " She " received 553,700 visitors over 5 months during the Swiss Expo.02 in 2002. In this paper we present the broad motivations, design and technologies behind Ada, and a first overview of the outcomes of the exhibit. Ada is an(More)
This paper describes the interactive tactile luminous floor that was constructed and used as the skin of the playful interactive space Ada, which ran as a public exhibit for five months in 2002 and had over 550,000 visitors. Ada's floor was custom-built to provide a means for individual and collective user interaction. It consists of 360 hexagonal 66 cm(More)
This paper presents a new system that allows for intuitive control of an additive sound synthesis model from perceptually relevant high-level sonic features. We suggest a general framework for the extraction, abstraction, reproduction and transformation of timbral characteristics of a sound analyzed from recordings. We propose a method to train, tune and(More)
Physiological experiments demonstrate the existence of weak pairwise correlations of neuronal activity in mammalian cortex (Singer, 1993). The functional implications of this correlated activity are hotly debated (Roskies et al., 1999). Nevertheless, it is generally considered a widespread feature of cortical dynamics. In recent years, another line of(More)
