In several experimental conditions, neuronal excitation at the perirhinal cortex (PC) does not propagate to the entorhinal cortex (EC) due to a “wall” of inhibition, which may help to create functional coupling and un‐coupling of the PC and EC in the medial temporal lobe. However, little is known regarding the coupling control process. Herein, we propose that the deep layer of area 35 in the PC plays a pivotal role in opening the gate for coupling, thus allowing the activity in (...) the PC to propagate to the EC. Using voltage‐sensitive dye imaging for the brain slices of rodents, we show that a slowly inactivating potassium conductance in this area is essential to induce excitation overtaking the inhibitory control. This coupling between the distinct neural circuits persists for at least 1 h. We elucidate further implications of this network‐level plastic behavior and its mechanism. (shrink)

This article considers the implications of the early development of London Zoo. It gives insight into the differences between the ideal image of the zoo, the real situation under which the zoo was managed, and popular perceptions of the zoo. The discussion explores three areas: the heterogeneous audience of the zoo, the aestheticization of the zoo and its animal displays, and the pedagogy of observing nonhuman animals in the zoo. The zoo's ideals confronted various difficulties, while the pedagogy of zoo (...) visits, which developed within a frame of natural theology, was subject to various applications. The article argues that these differences were not evidence of the zoo's failure to consolidate its ideological backbone in Victorian society. It concludes that such divergence characterized the zoo's unique capacity both to evoke and to receive competing ideals, anxieties and criticism. (shrink)

ABSTRACTAnother individual’s gaze automatically shifts an observer’s attention to a location. This reflexive response occurs even when the gaze is presented subliminally over a short period. Another’s gaze also increases the preference level for items in the gaze direction; however, it was previously unclear if this effect occurs when the gaze is presented subliminally. This study showed that the preference levels for nonsense figures looked at by a subliminal gaze were significantly greater than those for items that were subliminally looked (...) away from. Targets that were looked at by a subliminal gaze were detected faster ; however, the participants were unable to detect the gaze direction. These results indicate that another individual’s gaze automatically increases the preference levels for items in the gaze direction without conscious awareness. (shrink)

Molecular and biochemical analysis of the biogenesis of peroxisomes has made rapid progress in recent years. Research on the mechanism of targeting of peroxisomal proteins has revealed that many, but not all, peroxisomal proteins have a conserved tripeptide motif in their carboxy‐terminal portions which is required for entry into peroxisomes; the topogenic signal mechanism thus differs in these instances from those employed in mitochondria and endoplasmic reticulum. Other factors involved in peroxisome biogenesis are also coming to light.

The paper attempts to construct a global model of a social contract using well-known metaphors of two great philosophers: Jean-Jacques Rousseau and John Locke. By modelling a global social contract, I mean the formulation of a social contract using two sets of data: one is global citizens' preferences about values and norms while the other is sovereign states' participation in multilateral treaties. Both Rousseau and Locke formulate their versions of social contract theories in the national context of eighteenth-century Europe. This (...) paper tries my hands on extending their theories to the global context. This paper attempts to link empirically the relationship between global citizens' preferences as gauged by the World Values Survey and sovereign states' participation in 120 multilateral treaties deposited to the United Nations. To see the link between citizens and treaties (quasi-legislative outcomes, sort of), dimensional similarities of the cosmos of citizens' preference and the cosmos of sovereign states' willingness to join multilateral treaties are examined. Once done, all the sovereign states are located in each of the two cosmoses, citizens and states, and the correlation coefficients between them are measured. Based on these empirical results, the nature of the global quasi-legislative process is clarified. Conclusions and implications are drawn. (shrink)

Call a sentential context semantically transparent if and only if all synonymous expressions are substitutable for one another in it salva veritate. Nathan Salmon has boldly advanced a refreshingly crisp semantic theory according to which belief contexts are semantically transparent. If he is right, belief contexts are much better behaved than widely suspected. Impressive as it is, this author does not believe that Salmon’s theory is completely satisfactory. This article tries to show that Salmon’s theory, in conjunction with a number (...) of auxiliary but important claims he makes to buttress the theory, seems to lead to failure of semantic transparency of belief contexts.

The paper explores the logical strength of Isbell's zig‐zag theorem using the framework of reverse mathematics. Working in, we show that is equivalent to Isbell's zig‐zag theorem for countable monoids: If B is a monoid extension of A, then is dominated by A if and only if b has a zig‐zag over A. Our proof of Isbell's zig‐zag theorem avoids use of strong comprehension axioms common in traditional proofs. We also analyze the strength of theorems concerning binary relations.
