This process is useful because it provides a quantitative analysis of how close we are to reaching our goal of describing the behaviors of these neurons, and responses to natural scenes will always be the standard again ...

... of a thalamic nucleus). Some other theories pointed out that selective attention is object-based [1] [8] [10] [26] or spacebased [22] [24] [26] [12]. These theories treated selective attention as a selection of What, Where, and Which [13]. Yet, selection in time has not been thoroughly investigated. ...

A coincidence detector neural network model of selective attention
... In addition to influence from top-down spatial goals, the neural activation of each stimulus is progressively modulated by top-down signals of semantic information. We propose that a correlation control mechanism that includes coincidence detector neurons determines the correlation between semantic ...
