    • 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
  • You can filter the results of your search by a date or date range, filling the appropriate boxes.

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:
The project focused on understanding how the brain can plastically change as a response to congenital deafness. In particular, we were interested in understanding: 1) whether and how the auditory cortex of the congenitally deaf processed information from the spared senses – and specifically visual input; 2) how that sensory (visual) was organized in the auditory cortex, if at all; and 3) how did that information reached the auditory cortex. That is, how did neuroplasticity change the auditory cortex (and other structures) of the congenitally deaf so that it processes information from different senses.
To do this, we proposed a series of tasks. First we wanted to understand how the auditory cortex of congenitally deaf individuals processed information from the other senses. In particular, could the auditory cortex of the congenitally deaf be neuroplastically modified to be populated by visual information? And if so, would it inherit aspects of the functional organization seen in visual cortex? Almeida and Colleagues (2015; Psychological Science) show that the auditory cortex of the deaf processes visual information and that it represents visual field location – a dimension that is ubiquitous of the visual cortex. We then focused on understanding whether we could see the typical organization of the auditory cortex (tonotopy) in the deaf. Would this organization still be present in the deaf? Striem-Amit, Almeida, and colleagues (2016) demonstrated that deaf individuals continue to show connectivity patterns that allow us to uncover the typical tonotopic organization. These two papers solve the issue of functional organization of the auditory cortex in the deaf, suggesting that this structure suffers strong plasticity that implements the organization of visual properties in its tissue, but also (perhaps partially) maintains the typical connectivity patterns that may give rise to tonotopy.
We then focused on trying to understand how visual information reaches the auditory cortex of the congenitally deaf. We posited that this visual information was reaching the auditory cortex (perhaps in part) via subcortical structures such as the thalamus, and/or the superior and inferior colliculi. We inspected whether this structures presented changes in volume that could be suggestive of a neuroplastic change of the kind that would be implemented if that structure was involved in passing (visual) information differently than in hearing individuals. The data shows that the structure that seems to have been modified in a consistent way in the deaf but not the hearing is the thalamus (Amaral et al, 2016).
