    • 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.

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.

Independent component analysis reveals atypical electroencephalographic activity during visual perception in individuals with autism

Abstract/Results: ABSTRACT:
BACKGROUND:
Individuals with autistic spectrum disorder (ASD) experience atypical visual perception, yet the etiology of this remains unknown. The aim of this study was to investigate the neural correlates of visual perception in individuals with and without ASD by carrying out a detailed analysis of the dynamic brain processes elicited by perception of a simple visual stimulus.
METHODS:
We investigated perception in 20 individuals with ASD and 20 control subjects with electroencephalography (EEG). Visual evoked potentials elicited by Gabor patches of varying spatial frequency and stimulus-induced changes in a- and ?-frequency bands of independent components were compared in those with and without ASD.
RESULTS:
By decomposing the EEG data into independent components, we identified several processes that contributed to the average event related potential recorded at the scalp. Differences between the ASD and control groups were found only in some of these processes. Specifically, in those components that were in or near the striate or extrastriate cortex, stimulus spatial frequency exerted a smaller effect on induced increases in a- and ?-band power, and time to peak a-band power was reduced, in the participants with ASD. Induced a-band power of components that were in or near the cingulate gyrus was increased in the participants with ASD, and the components that were in or near the parietal cortex did not differ between the two groups.
CONCLUSION:
Atypical processing is evident in individuals with ASD during perception of simple visual stimuli. The implications of these data for existing theories of atypical perception in ASD are discussed.

Mindfulness-induced changes in gamma band activity - Implications for the default mode network, self-reference and attention
Publication year: 2012
URL:
http://www.clinph-journal.com/article/S1388-2457(11)00602-X/abstract
Abstract/Results: ABSTRACT:
OBJECTIVE:
There is a growing scientific interest in mindfulness meditation (MM), yet its underlying neurophysiological mechanism is still uncertain. We investigated whether MM affects self-referential processing, associated with default mode network (DMN), either as short (state) - or long-term (trait) effects.
METHODS:
Three levels of MM expertise were compared with controls (n=12 each) by electroencephalography (EEG).
RESULTS:
DMN deactivation was identified during the transition from resting state to a time production task, as lower gamma (25-45 Hz) power over frontal and midline regions. MM practitioners exhibited a trait lower frontal gamma activity, related to narrative self-reference and DMN activity, as well as producing longer durations, these being negatively correlated with frontal gamma activity. Additionally, we found state increases in posterior gamma power, suggesting increased attention and sensory awareness. MM proficiency did not affect the results.
CONCLUSIONS:
Gamma power over frontal midline areas reflects DMN activity. MM practitioners exhibit lower trait frontal gamma activity, as well as a state and trait increases in posterior gamma power, irrespective of practice proficiency.
SIGNIFICANCE:
First, the DMN can be studied non-invasively by EEG. Second, MM induces from the early stages of practice neuroplasticity in self-referential and attentional networks.
