A computational model was developed to explain a pattern of results of fMRI activation in the intraparietal sulcus (IPS) supporting visual working memory for multiobject scenes. The model is based on the hypothesis that dendrites of excitatory neurons are major computational elements in the cortical circuit. Dendrites enable formation of a competitive queue that exhibits a gradient of activity values for nodes encoding different objects, and this pattern is stored in working memory. In the model...

In the research on language understanding, context is defined in terms of words that help to construct the meaning of the target word or passage of text. Here, it is argued that the definition of context in language understanding should be broader in order to incorporate perception as an essential component of meaning. A theory of perceptual symbol systems is provided as a framework for understanding the role of perception in solving the symbol grounding problem for higher-level cognition. Theor...

Recent psychophysical and neurophysiological investigations showed that visual systemencodes luminance and use it to estimate illumination and surface brightness. We proposed anovel neural model for luminance coding based on recurrent inhibition, from the retinalganglion cells to the axons of the bipolar cells, which modulates the amount of sensory inputthat ganglion cells receive (Sagdullaev et al., 2006). Extended version of the model, where theamount of presynaptic inhibition is made proporti...

Investigations with children showed that they gradually develop an approximate representation of magnitude (numerosity). Lipton and Spelke (2004) investigated the children capacity to distinguish sequences of sounds. Six month babies were able to discriminate sequence with 16 sounds from the sequence of 8 sounds. However, they were not able to discriminate between sequences of 12 and 8 sounds. On the other hand, nine month babies were able to discriminate sequences of 12 and 8 sounds. Similar pr...
