We first deal with the upper semicontinuity, presenting the abstract theory and applying it to uniform perturbations of a nonautonomous integrate-and-fire neuron model. We also present the abstract theory of weak-lower semicontinuity, and finish with an improvement of [11,Subsection 4.2], proving an invariance property for impulsive pullback omega-limits with weaker assumptions.engjournal articlehttps://doi.org/10.3934/dcdsb.2020252https://www.aimsciences.org/article/doi/10.3934/dcdsb.2020252restricted accessImpulsive evolution processesPullback attractorsUpper semicontinuityWeak-lower semicontinuityNonautonomous integrate-and-fire modelOmega-limitsMatemáticas (Matemáticas)12 Matemáticas
