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:
BACKGROUND
A currently popular theory, the Functional Equivalence Model, holds that motor imagery and overt action use similar brain regions and have similar outputs, such as timing. This model is being contested by the Motor Cognitive Model, which posits that significant differences exist between the two behaviours, specifically that motor imagery relies heavily on executive resources involving the dorsolateral prefrontal cortex, whereas overt actions do not.
AIMS
To test the two aforementioned models of motor imagery by disrupting the activity of the dorsolateral prefrontal cortex while participants performed either motor imagery or overt actions (Experiment 1). To further test the models also using a task which interferes with executive functions (Experiment 2).
METHOD
In Experiment 1, participants had transcranial magnetic stimulation applied over their dorsolateral prefrontal cortex, disrupting its function, while carrying out tasks involving motor imagery or overt action. Behavioural tasks tested the efficacy of the disruption on various executive functions. Experiment 2 was similar, except that a behavioural interference task (backwards calculation) was added to further impact executive functions.
RESULTS
Disruption of the dorsolateral prefrontal cortex in both experiments affected the timing of motor imagery but not overt actions. Similarly, interfering with executive functions using the backwards calculation task had much greater effects on the timing of motor imagery than on overt actions.
CONCLUSIONS
The two experiments conducted here provided strong support for the Motor Cognitive Model over the Functional Equivalence Model, by showing the critical importance of executive functions, subserved by the dorsolateral prefrontal cortex, in motor imagery but not overt actions. Future studies will employ other neuroscientific and behavioural methods to test these theories further.
