Abstract: Visual attention is a process of sustained concentration on a specific stimulus. This concentration can be increased by activating the nucleus basalis in the basal forebrain using the spiking neuron model. Input stimulus is converted into spikes. Neurons are transmitting information in the form of pulse. By using this information spiking neuron model for the basal forebrain is simulated. Bottom-up and top-down method is used in lateral geniculate nucleus (LGN). The feedback connections are applied in the visual cortex for the enhancement of visual attention. To analyse the performance of spiking and oscillatory model segmentation and separation accuracy are obtained which shows the oscillatory model produce better accuracy for visual stimuli.

Keywords: visual attention; spiking neurons; nucleus basalis; bottom-up top-down method; sustained concentration; basal forebrain; simulation; lateral geniculate nucleus; LGN; feedback connections; visual cortex; oscillatory model; visual stimuli.
