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:
BACKGROUND:
There are reports of atypical visual perception in individuals with autistic spectrum disorder (ASD) yet the aetiology of this remains unknown. It is currently unclear at what stage atypical perception arises in autism; whether it is specific to certain classes of perceptual stimuli; or whether it reflects impairments in low or higher-level mechanisms.
METHOD:
We investigated perception in 20 individuals with ASD and 20 matched controls by measuring visual evoked potentials (VEP) elicited by Gabor patches presented at a range of spatial frequencies.
RESULTS:
The latency to peak of the visual evoked potential, elicited by all spatial frequencies was significantly reduced in the individuals with ASD compared to the typically developing individuals (effect sizes ranged from -.65 - -1.53).
CONCLUSION:
Atypical perception in autism occurs at an early stage of processing. It is apparent at a cortical level within 90 ms of stimulus onset and following presentation of very simple visual stimuli. We argue that autistic spectrum disorder is characterised by a low-level abnormality within the visual system.

Vestibular inputs modulate somatosensory cortical processing
Publication year: 2012

Abstract/Results: ABSTRACT:
The vestibular system is unique among the senses because of the entirely multisensory nature of its cortical projections. Neuroanatomical and neuroimaging studies show that vestibular stimulation activates somatosensory areas, and particularly the so-called parieto-insular vestibular cortex (PIVC) in the monkey, while deactivating visual areas. Further, recent psychophysical studies showed that vestibular stimulation facilitates detection of electrocutaneous stimuli, suggesting a vestibular-somatosensory perceptual interaction. However, the functional mechanism underlying this perceptual facilitation remains unclear. We therefore recorded somatosensory potentials evoked by left median nerve stimulation, before and immediately after left cold caloric vestibular stimulation (CVS), in a small-scale study of eight healthy volunteers. CVS selectively enhanced the N80 component recorded over both ipsilateral and contralateral somatosensory areas, without significantly affecting earlier or later components. Interestingly, the N80 component has been localised to the parietal operculum, which includes the human homologue of the monkey PIVC, and is thus a prime neuroanatomical candidate for vestibular-somatosensory convergence. As a control, we measured visual evoked potentials to reversing checkerboard patterns and found no effects of vestibular stimulation. This rules out explanations based on indirect effects of vestibular modulations, such as general arousal or supramodal spatial attention. We believe our results provide the first clue linking brain structure to function for the interaction between vestibular and somatosensory systems.

Correlations between brain electrical activities of two spatially separated human subjects
Publication year: 2003

URL: http://www.sciencedirect.com/science/article/pii/S030439400201248X
Abstract/Results: ABSTRACT:
Six channels electroencephalogram (EEG) were recorded simultaneously from pairs of separated human subjects in two acoustically and electromagnetically shielded rooms. While brain electric responses to visual pattern-reversal stimuli were elicited in one subject, the other subject relaxed without stimulation. EEGs of both subjects were averaged at times of stimulus onset, effective voltage of the averaged signals was computed within a running window, and expressed as ratio (Q) to the effective voltage of averaged EEG signal from non-stimulation periods. These ratios in non-stimulated subjects at the latency of the maximum response in stimulated subjects were analysed. Significant departures of Q ratios from reference distributions, based on baseline EEG in non-stimulation periods, were found in most non-stimulated subjects. The results indicate that correlations between brain activities of two separated subjects may occur, although no biophysical mechanism is known.
