Multiple instantiation is the ability to handle different instances of the same concept simultaneously. For example, from the following two facts: 'Pepin the Short was the son of Charles Martel' and 'Charlemagne was the son of Pepin the Short', one can infer that Charles Martel was the grandfather of Charlemagne. This inference requires two instantiations of 'Pepin the Short', the first in the role of son, the second in the role of father. For a connectionist model that does not use a working area receiving copies of items from a long-term knowledge base, the problem of multiple instantiation is a particularly thorny one. People are able to deal with multiple instances, unlike most connectionist models, but nonetheless their performance when doing so is reduced. On the other hand, there is no decrease in performance for symbolic models doing multiple instantiation. A good cognitive model should reflect both human competence and human limitations. This review proposes several connectionist solutions to the problem of multiple instantiation and examines their merits. [less ▲]

This paper presents a connectionist model of human reasoning that uses temporal relations between node firing. Temporal synchrony is used for representing variable binding and concepts. Temporal succession serves to represent rules by linking antecedent to consequent parts of the rule. The number of successive synchronies is affected by two well-known neurobiological parameters, the frequency of neural rythmic activity and the precision of neural synchronization. Reasoning is predicted to be constrained by these variables. An experiment manipulating the amount of successive synchronies is presented. Experimental results would seem to confirm the predictions.

Eurocode 3 Part 1-8 provides detailed application rules for the design of bolted end-plate connections. Although these rules apply to connections with any number of vertical bolt rows, most of them are limited to configurations with two bolts only in each horizontal row, i.e. one bolt on each side of the beam or column web. However, it is sometimes more economic to place four bolts in one row, for instance when wide flange H-sections are used. This configuration is commonly met in different countries in Europe and, in particular, in Germany where this configuration is even standardized. The theoretical model on which the Eurocode 3 application rules are founded is general and can be potentially applied to connections with four bolts per horizontal row. However, specific design rules are not given in Eurocode 3 and need to be developed. Within the present article, easy-to-apply analytical design rules aimed at predicting the mechanical properties of connections with four bolts per row, being in full agreement with the Eurocode 3 approach, are presented. In particular, comparisons to less recent analytical procedures are given. [less ▲]

mmunofluorescent staining of frozen sections of rat bone marrow for collagen types I and III revealed the presence of a distinctive, collagen-producing cell type. Morphologically, these cells closely resembled reticular cells. They were large, with branching cytoplasm and were closely related to an extensive intercellular matrix of collagenous material that surrounded the hematopoietic cells of the marrow. Biochemical studies demonstrated synthesis of collagen types I and III, in a ratio of 4:1, by fresh rat bone marrow cells. [less ▲]

The mechanisms underlying anesthesia-induced loss of consciousness remain a matter of debate. Recent electrophysiological reports suggest that while initial propofol infusion provokes an increase in fast rhythms (from beta to gamma range), slow activity (from delta to alpha range) rises selectively during loss of consciousness. Dynamic causal modeling was used to investigate the neural mechanisms mediating these changes in spectral power in humans. We analyzed source-reconstructed data from frontal and parietal cortices during normal wakefulness, propofol-induced mild sedation, and loss of consciousness. Bayesian model selection revealed that the best model for explaining spectral changes across the three states involved changes in corticothalamic interactions. Compared with wakefulness, mild sedation was accounted for by an increase in thalamic excitability, which did not further increase during loss of consciousness. In contrast, loss of consciousness per se was accompanied by a decrease in backward corticocortical connectivity from frontal to parietal cortices, while thalamocortical connectivity remained unchanged. These results emphasize the importance of recurrent corticocortical communication in the maintenance of consciousness and suggest a direct effect of propofol on cortical dynamics. [less ▲]

Thirteen chronic tinnitus patients and fifteen age-matched healthy controls were studied on a 3T magnetic resonance imaging (MRI) scanner during resting condition (i.e. eyes closed, no task performance). The auditory resting-state component was selected using an automatic component selection approach. Functional connectivity (correlations/anti-correlations) in the extracted network was portrayed by integrating the independent component analysis (ICA) approach with a graph theory method. Tinnitus and control groups showed different graph connectivity patterns. In the control group, the connectivity graph was divided into two distinct anti-correlated networks. The first one encompassed the auditory cortices and the insula. The second one encompassed frontoparietal and anterior cingulate cortices, brainstem, amygdala, basal ganglia/nucleus accumbens and parahippocampal regions. In the tinnitus group, only one of the two previously described networks was observed, encompassing the auditory cortices and the insula. Direct group comparison showed, in the tinnitus group, an increased functional connectivity between auditory cortices and the left parahippocampal region surviving multiple comparisons. We investigated a possible correlation between four tinnitus relevant measures (tinnitus handicap inventory (THI) and tinnitus questionnaire (TQ) scores, tinnitus duration and tinnitus intensity during the scanning session) and the connectivity pattern in the tinnitus population. We observed a significant positive correlation between the beta values of the posterior cingulate/precuneus region and the THI score. Our results show a modified functional connectivity pattern in tinnitus sufferers and highlight the role of the parahippocampal region in tinnitus physiopathology. They also point out the importance of the activity and connectivity pattern of the posterior cingulate cortex/precuneus region to the development of the tinnitus associated distress.
