Correlation of brain rhythms between frontal and left temporal (Wernicke's) cortical areas during verbal thinking

The aim of this study was to investigate an interaction between frontal and left temporo-parietal cortices in tasks requiring word association. A new method was used to examine averaged event-related potentials in different frequency bands by calculating correlation coefficients between wavelet curves in distant cortical areas. This method was applied to previous event-related potentials recording

Complexity of electrocortical dynamics in children : Developmental aspects

Dimensional complexity (DCx) is an EEG measure derived from nonlinear systems theory that can be indicative of the global dynamical complexity of electrocortical activity. This study examined developmental changes in DCx, as well as the effects of cognitive tasks, gender, and brain topography, and compared DCx with traditional spectral power measures. EEG was recorded in three groups of children a

Age increases brain complexity

This study investigated age-related changes in the human brain function using both traditional EEG analysis (power spectra) and the correlational dimension, a measure reflecting the complexity of EEG dynamics and, probably, the complexity of neurophysiologicaI processes generating the EEG. Assuming that the accumulation of individual experience is determined by the formation of functionally relate

Cortical connectivity during word association search

Cortical connectivity was studied in tasks of generating the use of words in comparison with reading aloud the same words. These tasks were used earlier in PET and high density ERP recordings studies (Posner and Raichle, 1997; Abdullaev and Posner, 1998), in which both the functional anatomy and the time course of cortical areas involved in word processing were described. The wavelet transforms of

Coping with autonomy: Managers’ responses to the pendulum between activity-based and fixed reimbursement systems in Swedish hospital care

Governance and management in publicly funded services includes the processes that governments use to ensure that the activities of organizations involved in the delivery of public services are in line with those expected. In hospital care, the reimbursement model is viewed as an important tool to motivate providers to act in the interest of the funding body. The purpose of this study was to analys

The European Union readmission policy after Lisbon

This article conducts a brief historical excursus on the evolution of the EU’s readmission policy through the analysis of readmission agreements, meant as its main legal instruments. The Lisbon Treaty is herein portrayed as an historical watershed in the recognition of both an express competence of the Union with regard to measures aimed to address the readmission of irregular migrants, and a new

Anthropology of Rape in War: Sexual Violence and Magical Beliefs in the Congo War.

This paper discusses the landscape of sexual violence in the DR Congo, it draws attention to agency, violence, personhood, emotions and understanding of sexual violence by perpetrators, victims and those organizations seeking to combat the phenomenon. DR Congo have been cited by international actors and media as a region where sexual violence is used "as a weapon of war" and women's situation is c
