Cognitive behavior requires complex context-dependent processing of information that partially emerges from the links between attentional perceptual processes and working memory. We describe a computational neuroscience theoretical framework which shows how an attentional bias can influence perceptual processing, the mapping of sensory inputs to motor output and formation of selective working memory...

We study the effect of finite-size synaptic noise on the response to time-varying stimuli of a detailed neurodynamical model of perceptual-decision making. Specifically, the reaction to a periodic stimulus is analyzed, while controlling the noise level through the number of neurons in the perception module. We find an enhanced response to the dynamical stimulus for intermediate noise, i.e. for an...
The aim of this study is to explore the nature of the semantic effects in the picture–word interference paradigm. In particular, we focused on the (a) identity effect, (b) semantic interference effect, (c) semantic facilitation effect, and the semantic facilitation in categorization. Our model is based on integrate-and-fire neurons which are put in a network context featuring modular competition and...
