    Reduction of conductance-based neuron models (1992)

    Notes: Abstract We present a scheme for systematically reducing the number of differential equations required for biophysically realistic neuron models. The techniques are general, are designed to be applicable to a large set of such models and retain in the reduced system as high a degree of fidelity to the original system as possible. As examples, we provide reductions of the Hodgkin-Huxley system and the A-current model of Connor et al. (1977).

    Spike initiation and propagation on axons with slow inward currents (1993)
    Springer
    Biological cybernetics 68 (1993), S. 209-214

    ISSN: 1432-0770

    Notes: Abstract We investigate spike initiation and propagation in a model axon that has a slow regenerative conductance as well as the usual Hodgkin-Huxley type sodium and potassium conductances. We study the role of slow conductance in producing repetitive firing, compute the dispersion relation for an axon with an additional slow conductance, and show that under appropriate conditions such an axon can produce a traveling zone of secondary spike initiation. This study illustrates some of the complex dynamics shown by excitable membranes with fast and slow conductances.

    Binding by temporal structure in multiple feature domains of an oscillatory neuronal network (1994)

    Notes: Abstract. An important step in visual processing is the segregation of objects in a visual scene from one another and from the embedding background. According to current theories of visual neuroscience, the different features of a particular object are represented by cells which are spatially distributed across multiple visual areas in the brain. The segregation of an object therefore requires the unique identification and integration of the pertaining cells which have to be “bound” into one assembly coding for the object in question. Several authors have suggested that such a binding of cells could be achieved by the selective synchronization of temporally structured responses of the neurons activated by features of the same stimulus. This concept has recently gained support by the observation of stimulus-dependent oscillatory activity in the visual system of the cat, pigeon and monkey. Furthermore, experimental evidence has been found for the formation and segregation of synchronously active cell assemblies representing different stimuli in the visual field. In this study, we investigate temporally structured activity in networks with single and multiple feature domains. As a first step, we examine the formation and segregation of cell assemblies by synchronizing and desynchronizing connections within a single feature module. We then demonstrate that distributed assemblies can be appropriately bound in a network comprising three modules selective for stimulus disparity, orientation and colour, respectively. In this context, we address the principal problem of segregating assemblies representing spatially overlapping stimuli in a distributed architecture. Using synchronizing as well as desynchronizing mechanisms, our simulations demonstrate that the binding problem can be solved by temporally correlated responses of cells which are distributed across multiple feature modules.

    Notes: The three birth cohorts which have passed through the youth stage of their life course since the founding of the People's Republic of China (PRC) in 1949 have had radically different relations with the Party-state. This has brought serious consequences for the Party-state itself, the Party-state's relation with succeeding youth cohorts and for the integration of Chinese society.

    Notes: Bands of young men took to the streets of Shanghai in late 1978, shouting slogans, vandalizing stores, putting up wall posters, imprisoning municipal officials in their offices and disrupting rail traffic. To many Shanghainese, it was déjà vu, a replay of Red Guard activities during the Cultural Revolution (CR), and small wonder, as the participants were those same youths who had rampaged through the city and then foresworn the urban security of Shanghai to go up to the mountains and down to the countryside to build socialism. Now, a decade later, disillusioned, alienated, in dire economic straits, unmarried and abandoned, they had ridden a “back to the city wind” and were determined to stay.

    Notes: The year 1985 marks the 20th anniversary of the publication in The China Quarterly of Ezra F. Vogel's classic article, “From friendship to comradeship: the change in personal relations in communist China.” The present article examines personal relations in China in the wake of the intervening two decades of Cultural Revolution (CR) and modernizing reforms. I will describe the major dimensions of personal relations in 1985 and offer a sociological explanation for them. My argument is that these relationships represent a re-emergence of certain traditional patterns as reshaped by both the CR and the current restructuring of state-society relations.
