Abstract
A model is proposed to explain the overall dynamic response range of intact chemoreceptor structures, by postulating an array of chemoreceptive cells with limited individual dynamic ranges. The model contends that the sensitivity ranges of chemoreceptive cells are governed by the extent of dendritic branching and predicts a population of chemoreceptive cells with differing sensitivity ranges. The rapid response time of biosensors incorporating intact chemosensory structures is also explained.
