It is difficult to be certain about brain functioning. Until now, most efforts to understand brain computations have only been conducted on a stand alone computer. In order to recreate the brain accurately, members of the Institute of Cognitive Computing Technology (ICCT) were interested in finding out whether or not a biological process could be simulated on a Distributed Artificial Neural Network (DANN). The goal of this investigation was to implement visual perception on a network of computers and compare the computations of the network with those of a human brain. The distributed network was developed as a Local Area …

Asking people to discover the identity of a recognition test probe immediately before making a recognition judgment increases the probability of an old judgment. To inform theories of this “revelation effect,” event-related potentials (ERPs) were recorded for revealed and intact test items across two experiments. In Experiment 1, we used a revelation effect paradigm where half of the test probes were presented as anagrams (i.e., a related task) and the other items were presented intact. The pattern of ERP results from this experiment suggested that revealing an item decreases initial familiarity levels and caused the revealed items to elicit similar …

This article outlines several distinctions in cognition and related topics in emotion that receive support from work in cognitive neuroscience and have important implications for prevention: implicit cognition, working memory, nonverbal memory, and neurobiological systems of habit. These distinctions have not been widely acknowledged or applied in drug use prevention research, despite their neural plausibility and the availability of methods to make this link. The authors briefly review the basis for the distinctions and indicate general implications and assessment possibilities for prevention researchers conducting large-scale field trials. Subsequently, the article outlines a connectionist framework for specific applications in prevention interventions. …

The visual modality typically dominates over our other senses. Here we show that after inducing an extreme conflict in the left hand between vision of touch (present) and the feeling of touch (absent), sensitivity to touch increases for several minutes after the conflict. Transcranial magnetic stimulation of the posterior parietal cortex after this conflict not only eliminated the enduring visual enhancement of touch, but also impaired normal tactile perception. This latter finding demonstrates a direct role of the parietal lobe in modulating tactile perception as a result of the conflict between these senses. These results provide evidence for visual-to-tactile perceptual …
