Start date: 1994
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
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.

Adaptation effects of emotional expressions in anxiety: Evidence for an enhanced late positive potential
Publication year: 2010
Abstract/Results: ABSTRACT:
Prolonged exposure to a stimulus biases perception of a subsequent stimulus away from the adapting stimulus (Clifford & Rhodes, 2005). These aftereffects have been observed with a wide variety of stimuli, including facial identity (Rhodes & Jeffery, 2006) and emotional facial expression (e.g., Webster et al., 2004). In the current experiment, we used this paradigm to examine the effect of anxiety on the perception of emotional expression. Photographs of a male and a female model from the Karolinska Directed Emotional Faces set (KDEF; Lundqvist et al. 1998) were selected and a series of morphs created by interpolating a fear exemplar with a neutral exemplar for each model. A pilot study established a range of morphed expressions falling on either side of the fear/neutral boundary, and these were then used in the main study. There were 16 adaptation blocks in the experiment proper, and each block began with an adapting phase in which participants viewed (and categorized) 35 presentations of one endpoint from the morph continuum. This was immediately followed by a test phase, during which participants viewed and categorized 33 images of the same model (8 dummy trials, 5 top-up trials and 20 test trials – 10 from either side of the categorical boundary). We predicted that all test trials would be perceived as having an emotional expression opposite to that of the adapting stimulus (e.g., adaptation to fear would produce ‘neutral’ classifications for the test stimuli that were originally on the ‘fear’ side of the boundary). EEG was recorded using a NeuroScan NuAmps system, and stimulus presentation was controlled using E-Prime. An analysis of the behavioural classification data revealed that adaptation to fear created a shift in the classification of morphs towards ‘neutral’ and adaptation to neutral created a shift towards ‘fear’. This shift was equivalent in high and low anxiety. An analysis of the ERP data, however, revealed a more pronounced late positive potential in the high, but not the low, anxiety group following adaptation to neutral compared to fear, and this effect was particularly enhanced for male than female expressions.
