    • The Boolean operator AND between the terms is assumed by default. If you enter the words European Union in the search box, the system returns all records in which both words occur, regardless of their order.
    • When entering a set of words in quotes, e.g "european union", all records containing the literal term "European Union" will be retrieved.
  • Search by access fields (e.g. author, title, etc.):
    • To direct your search, choose the field in which you want to search the word or expression.
    • Search in the field assumes by default the expression in quotes, e.g. European union will retrieve all records containing the literal term "European Union"
  • To perform more complex searches, additional words or expressions may be added.
  • If you want to refine the search results, you can always access the link "search" in the upper left corner of the page of search results.
  • The search engine is not case sensitive. For example, the word congress has the same meaning that Congress or CONGRESS.
  • To truncate your search expression, use the $ character

BIAL Foundation Archive
Start date: 1994
History:
The BIAL Foundation was created in 1994 by Laboratórios BIAL in conjunction with the Council of Rectors of Portuguese Universities. BIAL’s Foundation mission is to foster the scientific study of Man from both the physical and spiritual perspectives.
Along the years the BIAL Foundation has developed an important relationship with the scientific community, first in Portugal and after worldwide. Today it is an institution of reference which aims to stimulate new researches that may help people, promote more health and contribute to new milestones to gain access to knowledge.
Among its activities the BIAL Foundation manages the BIAL Award, created in 1984, one of the most important awards in the Health field in Europe. The BIAL Award rewards both the basic and the clinical research distinguishing works of major impact in medical research.
The BIAL Foundation also assigns Scientific Research Scholarships for the study of neurophysiological and mental health in people, arousing the interest of researchers in the areas of Psychophysiology and Parapsychology.
To date the BIAL Foundation has supported 461 projects, more than 1000 researchers, with research groups in twenty-seven countries, resulting, until April 2013, in about 600 full papers, out of which 172 published in indexed international journals with an average impact factor of 3.6 and a substantial number of citations (1665).
Since 1996 the BIAL Foundation organizes the Symposia entitled "Behind and Beyond the Brain", a Forum that gathers well renowned neurosciences speakers and the BIAL Foundation Fellows which are spread around the world.
Classified as an institution of public utility, the BIAL Foundation includes among its patrons the Portuguese President, the Portuguese Universities Rectors' Council and the Portuguese Medical Association.

Title: BIAL Grants
Start date: 1994
History:
In 1994 the BIAL Foundation launched a programme of science research grants with the aim of encouraging the research into Man’s physical and mental processes, namely in fields still largely unexplored but which warrant further scientific analysis, as Psychophysiology and Parapsychology.
Since its launch, applications to the BIAL grants have been increasing. Up to now 461 projects have been supported, involving more than 1000 researchers from 27 countries.
The approved applications have benefited from grants in amounts comprised between €5,000 and €50, 000. The amount to be granted is fixed by the Scientific board according to the needs of each project.
The supported projects have originated, until April 2013, in about 600 full papers, 172 out of which were published in indexed international journals with an average impact factor of 3.6 and a substantial number of citations (1665).
Among the BIAL Foundation fellows is worth highlighting the presence of scientists from prestigious universities from the United States, United Kingdom, Australia, Russia, Germany, Japan, France, Canada, and many others.
The BIAL grants are promoted biannually.

Abstract/Results: ABSTRACT:
OBJECTIVES:
An adaptation paradigm was used to examine the effect of context on emotional expression processing in anxiety. We predicted that fear/neutral morphs would be more likely to be classified as ‘fearful’ following neutral adaptation and ‘neutral’ following fearful adaptation. We examined several ERP components (P1, EPN and the LPP) in order to investigate the time course of differential processes involved in ambiguity resolution and whether these effects are modulated by anxiety.
METHODS:
A male and a female model were selected and fear/neutral morphs created. Participants classified test trials following adaptation to the fear or neutral exemplar. 16 test blocks were presented, and participants classified the emotional expression of each test trial. EEG was recorded using a NeuroScan NuAmmps system, and stimulus presentation was controlled using EPrime. The high temporal resolution of the EEG technique enabled us to examine the locus of the expression aftereffects in anxiety. Several ERP components were examined to see if they were modulated by anxiety.
RESULTS:
There was a shift in the behavioural classification of morphs towards ‘fear’ following adaptation to the neutral exemplar compared to adaptation to the fear exemplar, and this shift was equivalent for high and low anxiety. The behavioural analysis revealed that the female face was classified as being fearful more often at baseline and following neutral adaptation compared to the male face. An analysis of the ERP data, however, revealed a more pronounced late positive potential, beginning at ~400 ms post-stimulus onset, in the high but not the low anxiety group following adaptation to neutral compared to fear.
CONCLUSIONS:
These data support the proposal that high anxiety is associated with increased sensitivity to contextual influences from top-down elaborative modulations, as reflected in an enhanced late positive potential deflection. These data offer support for an increase in sensitivity to context in high anxiety.
DISCUSSION:
The adaptation paradigm combined with behavioural report and EEG is a useful technique for examining the effect of context on categorization of ambiguous information. These data reveal a late effect of context on categorization in anxiety.
