Dissociable contributions of left and right dorsolateral prefrontal cortex in planning.

2010

It is well established that the mid-dorsolateral prefrontal cortex (dlPFC) plays a critical role in planning. Neuroimaging studies have yielded predominantly bilateral dlPFC activations, but the existence and nature of functionally specific contributions of left and right dlPFC have remained elusive. In recent experiments, 2 independent parameters have been identified which substantially determine planning: 1) the degree of interdependence between consecutive steps (search depth) and 2) the degree to which the configuration of the goal state renders the order of single steps either clearly evident or ambiguous (goal hierarchy). Thus, search depth affects the actual mental generation and eva…

Chronometry of parietal and prefrontal activations in verbal working memory revealed by transcranial magnetic stimulation.

2003

We explored the temporal dynamics of parietal and prefrontal cortex involvement in verbal working memory employing single-pulse transcranial magnetic stimulation (TMS). In six healthy volunteers the left or right inferior parietal and prefrontal cortex was stimulated with the aid of a frameless stereotactic system. TMS was applied at 10 different time points 140-500 ms into the delay period of a two-back verbal working memory task. A choice reaction task was used as a control task. Interference with task accuracy was induced by TMS earlier in the parietal cortex than in the prefrontal cortex and earlier over the right than the left hemisphere. This suggests a propagation of information flow…

System and flexibility in law

1991

Usually, rhetoric is supposed to provide a model of law which describes legal interactions as volitive, arbitrary, and void of any system. However, the Mainz School, founded by Theodor Viehweg, proves the contrary: without referring to any metaphysics, such as consensus or auditoire universel, it seeks to discover the systematic character and the more or less flexible structures of legal rhetoric.

Hibridisme i autoreferència en el fantàstic d'Espiral, de Manuel Baixauli

2018

The aim of this paper is to define and to analyse the fantastic universe of short stories by Manuel Baixauli published in the volume Espiral (2010), an original and highly significant example of modern fantastic literature that has abolished the real and imaginary borders, that is to say a significant example of fantastic literature conceived as a language phenomenon. The conception of reality integrates and naturalises the supernatural and the irrational in a vision that joins multiple dimensions and perspectives of reality. The self-referential component is also of essential importance in this fantastic, which assimilates and exhibits themes and motifs of inherited traditions in a fully c…

Segregation of areas related to visual working memory in the prefrontal cortex revealed by rTMS.

2002

The functional organization of working memory (WM) in the human prefrontal cortex remains unclear. Storage and processing functions might be segregated in ventral and dorsal areas of the prefrontal cortex, respectively. If so, storage functions might be spared, irrespective of informational domain, following damage or dysfunction in dorsolateral areas. Alternatively, WM and prefrontal function in general might be segregated according to informational domains (e.g. spatial versus object-based information). In the present study we used repetitive transcranial magnetic stimulation (rTMS) to directly test these competing hypotheses. We applied rTMS to transiently and selectively disrupt the fun…

Phenomenal transparency and cognitive self-reference

2003

A representationalist analysis of strong first-person phenomena is developed (Baker 1998), and it is argued that conscious, cognitive self-reference can be naturalized under this representationalist analysis. According to this view, the phenomenal first-person perspective is a condition of possibility for the emergence of a cognitive first-person perspective. Cognitive self-reference always is reference to the phenomenal content of a transparent self-model. The concepts of phenomenal transparency and introspection are clarified. More generally, I suggest that the concepts of “phenomenal opacity” and “phenomenal transparency” are interesting instruments for analyzing conscious, self-represen…

Eliminating self-reference from Grelling's and Zwicker's paradoxes

2014

El objetivo de este artículo es ofrecer versiones de las paradojas de Grelling (sobre el predicado"heterológico") y de Zwicker (sobre el hiperjuego) inspiradas en la paradoja de Yablo. Nuestras versiones de estas paradojas no parecen involucrar ni autorreferencia ni circularidad viciosa. The goal of this paper is to present Yabloesque versions of Grelling¿s and Zwicker¿s paradoxes concerning the notions of ¿heterological¿ and ¿hypergame¿ respectively. We will offer counterparts of these paradoxes that do not seem to involve self-reference or vicious circularity.
