Current evidence suggests that local field potential activity in the whisker barrel cortex ofawake mice is phase locked to respiration . In our study,we discuss the relevance among local fieldpotential signals,respiration and visual stimulation.First,we obtain data from EEGs including twoaspects:(1 )the state of asleep;(2)the state of awake:(a)no visual stimulation;(b)a visual stimulus ofCheckboard. Second,through some calculating models, such as:Double Exponential SmoothingMethod, Multiple line
