Toward a Neurobiological Theory of Visual Attention
Abstract
We started the construction of a system-level simulation package incorporating the ideas of temporal tagging for attentional modulation of neuronal signals into a model of several interacting cortical and subcortical areas using video-camera acquired images. This simulation differs significantly from connectionist models, since the temporal structure of the neural signals plays a crucial role in the coding of attentional state. Thus, we use single neuron models with quasi realistic temporal behavior. In particular, we exclude all models in which the activity of a neuron is measured only by average firing rate. Instead, we assume a spiking mechanism, and that the communication between neurons has to be accomplished by the exchange of potentials.
