Abstract: Senses and cognition of humans are mainly done by the visual nervous system. Most of the information people absorb from the world all conducted by the visual system. Therefore, visual attention mechanism is very important for exploring the visual system. In this paper, several basic problems of visualization of cellular electrical activity and visual information processing in the central nervous system are reviewed; then, models of visual attention mechanism are systematically reviewed. Finally, application of the visual attention mechanism in medical image segmentation is discussed.

Abstract: We propose a variant of the SEIZ mathematical model originally proposed by Bettencourt et al, where the rumor spreads between two different scenarios Z1 and Z2 which do not share information with each other. This model is studied analytically where we include a new parameter μ for forgetting a rumor. We show results that were obtained using this model for a certain case in Venezuela. Finally, we also provide the numerical code for the numerical integration in order to provide a useful tool for others in their investigations.
