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.

Title:
Plasticity changes in the brain in hypnosis and meditation
Publication year: 2009

Abstract/Results: ABSTRACT:
Neuroscientific evidence interprets both hypnotic trance induction and different meditation traditions as modified states of consciousness that emphasize attention, concentration and the letting go of thoughts, but they differ in terms of sensory input, processing, memory, and the sense of time. Furthermore, hypnosis is based on the suggestibility of a person and meditation on mindfulness; therefore it is not surprising to find differential brain plasticity changes. We analysed shared and non-shared neural substrates using electroencephalography (EEG), positron emission tomography (PET), and functional magnetic resonance imaging (fMRI). Most pronounced EEG changes were in deep as compared to light hypnosis (step-by-step induction) and in arm levitation where suggested movement was perceived as external. In a within-subject-design changes in brain activity during hypnosis and Tibetan Buddhist meditation were compared. High amplitudes in alpha frequency bands were most pronounced with meditation at frontal positions and with hypnosis in central and temporal locations. Significantly greater activity in theta 2 band was observed only with hypnosis in both hemispheres. PET cerebral activation patterns of imagery-mediated learning were analysed in hypnosis in a within-subject-design. Compared with baseline the learning of high-imagery words was associated with (i) more pronounced bilateral activation in the occipital cortex and prefrontal areas and (ii) improved memory performance. Visual illusion in hypnosis was studied with fMRI, analysed with Granger Causality Mapping, showing changes in the effective connectivity relations of fusiform gyrus, anterior cingulate cortex and intraparietal sulcus. Little is known about the neurobiological basis of the process of enhancing cognitive and emotional traits in meditation. In a longitudinal fMRI study attention abilities through intensive Soto-Zen meditation were investigated before (baseline), after training (6 months) and at follow-up (9 months). After six months differences were observed in the left inferior and left superior frontal gyrus; after 9 months activations in the left precuneus. Taken together, the findings advance understanding of the neural mechanisms that underlie hypnosis and meditation. Further studies with a greater sample size are needed to explore the differences and commonalities of hypnosis and different meditation techniques.

Abstract/Results: ABSTRACT:
Neurofeedback is a brain-based training method that enables a user to control their own cortical oscillations by feed-back of real-time information from EEG (electroencephalogram) activity. The objective of our study was to assess the capability of EEG-based neurofeedback to induce dopamine release in-vivo using Positron Emission Tomography (PET). However, our current knowledge of how neurofeedback induces neurophysiological changes in the brain remains limited. Importantly, no investigations exist exploring the potential impact of neurofeedback on the brain’s key neuromodulatory systems. Thirty-two healthy volunteers were randomised to either EEG-neurofeedback (NFB) or EEG-electromyography (EMG), and scanned while performing this task during a single session of dynamic Positron emission tomography (PET) brain imaging. Dopamine binding kinetics were measured with high affinity D2/3 receptor ligand, [18F] Fallypride and radioligand displacement was quantified in thalamic and prefrontal cortical regions of interest (ROI) to determine effects of neurofeedback on endogenous dopamine release. Contrary to our hypothesis of a differential effect for NFB vs EMG training, significant dopamine release was observed in both training groups in the prefrontal cortex. Overall, our findings constitute the first investigation of neurofeedback’s effect on the endogenous release of a key neuromodulator, demonstrating its feasibility and paving the way for future studies using this methodology.
