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: RESULTS:
In this Project, we have investigated memory mechanisms in the human visual system, by employing a combination of psychophysics and functional magnetic resonance imaging (fMRI) methodologies to identify the neural correlates of different types of learning processes. For this purpose, we implemented and optimized a number of fMRI visual mapping paradigms in order to identify the visual brain areas of interest.
We first observed the adaptive functional reorganization of visual memory in a population of temporal lobe epilepsy patients with right unilateral hippocampal sclerosis. We used fMRI to measure brain activity changes during the episodic encoding of abstract line drawings and found that the patients engaged the left hippocampus more than controls and that the level of engagement was correlated with their memory recognition scores. These finds suggested functional reorganization of visual memory with an adaptive role, as a consequence of prolonged disease. We also found that familiar items activated visual cortical areas more than novel items, suggesting a reinstatement of visual information as a consequence of learning.
In a second study, we implemented a visual learning paradigm whereby subjects performed a face discrimination task on faces presented in multiple orientations, in order to investigate the hypothesis that the human visual system contains specialized processing mechanisms that are more engaged by upright faces than by inverted faces or non-face objects, as a result of extensive practice with upright faces. Our psychophysics experiments showed that participants gave more errors and were slower in their responses as faces were rotated away from 0º. In addition, performance was improved when participants underwent periods of training, both for trained and untrained orientations. Consistently with the expertise hypothesis, we also found a parametric modulation of fMRI activity in specialized visual brain areas, according to the quadratic behavioural effect of face orientation.

Perceptual learning for multiple face orientations

Abstract/Results: ABSTRACT:
The well-established face inversion effect refers to a declination of performance for inverted compared to upright faces. However, perceptual learning for faces presented in non-upright orientations has not been systematically investigated. We conducted two experiments in which we investigated perceptual learning for multiple face orientations over short periods of time (Experiment 1) and for a single orientation over long-term training (Experiment 2). In Experiment 1, participants performed a same - different discrimination task (DT) on pairs of faces presented in orientations ranging between 0 and 300°. A quadratic effect was observed across orientations for both reaction times and error rates, indicating a deterioration of performance away from 0° and towards 180°. Moreover, we found that error rates as well as reaction times significantly decreased across blocks of trials, indicating a learning effect. In Experiment 2, participants carried out the DT over the course of four consecutive days (4 sessions) on faces with a single orientation (120°). Here, we observed a main effect of session, indicating that participants became significantly faster and more accurate with training. Finally, when tested with a different orientation (240°) at the end of the last session, participants showed a similar performance compared with the trained orientation (120°), suggesting that transfer of learning across orientations took place.
