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:
OBJECTIVES:
The relationship between time in dreams and real time has intrigued scientists for centuries (cf. Schredl, 2000). In a recent study by Erlacher and Schredl (2004) it was shown that the required time to perform a motor task in a lucid dream was significant longer than the required time for the same task in the waking state. In contrast, the time intervals for counting were quite similar in lucid dreams and in wakefulness. In this experiment a simple cognitive task was used to investigate the relationship between the time needed in a lucid dream and the time needed for the same activity performed in the waking state.
METHODS:
Two experiments were conducted whereas in experiment 1 the participant’s task was to count to 10, 20, and 30 and in experiment 2 to walk 10, 20, and 30 steps in their lucid dreams. The lucid dreamers were instructed to mark the events by LRLR: the onset of lucidity, the beginning of each sequence and the end of the lucid dream task. The LRLR are clearly visible in the EOG recording and the interval between two LRLR can be measured. Sleep was recorded by means of standard procedures (EEG, EOG, EMG) by the standard recording device Trex Longtime EEG recorder (XLTEK).
RESULTS:
For the first and second experiment the results showed that the absolute duration of counting or walking in the lucid dream takes more time than for counting or walking during wakefulness. The relative timing, however, revealed for both conditions quite similar percentages for the two conditions (lucid dreaming and wakefulness).
DISCUSSION:
The results showed that in lucid dreams a tendency exists to overestimate durations for simple cognitive and motor tasks, but, that those differences are not visible for the relative timing of the tasks. In general the statistical analysis has to face the problem of testing for equivalence, because the alternative hypothesis predicts a similar result and not a difference (c.f. Wellek, 2003).

Abstract/Results: ABSTRACT:
BACKGROUND
Under natural conditions, the nervous system and the body of a moving animal interact continuously, and it is from this interaction that neural circuits form internal representations that guide animal behaviour, including our own. We focus on two internal representations: spatial perception and self-movement estimation. These representations depend on multimodal sensory-motor integration. How this integration is implemented across neural circuits is still an open question.
AIMS
To answer this question, we study how movement is incorporated to visual motion processing into: 1) guide oriented behaviors, and 2) to estimate self-movement.
METHOD & RESULTS
We combined anatomical, electropysiological and optical techniques, and identified novel visual neurons sensitive to small-field visual motion stimuli in the fruitfly Drosophila melanogaster. We are currently assessing their role in spatial orientation by reversible manipulations of their activity in behavioral paradigms we developed for oriented locomotion. For the second aim, we performed electrophysiological recordings from optic-flow sensitive neurons during explorative walking and found that these cells represent the fly’s walking movements accurately (even in the absence of vision) by integrating visual and walking-related motor signals.
CONCLUSIONS
The identified novel visual neurons open the opportunity to study their role in orientated behaviors to understand how the brain combines walking with visual processing to create spatial perception. In addition, we demonstrated that optic-flow sensitive neurons receive non-visual detailed information about the walking movements of the fly to create a faithful representation of self-movement.

A faithful internal representation of walking movements in the Drosophila visual system

Abstract/Results: ABSTRACT:
The integration of sensorimotor signals to internally estimate self-movement is critical for spatial perception and motor control. However, which neural circuits accurately track body motion and how these circuits control movement remain unknown. We found that a population of Drosophila neurons that were sensitive to visual flow patterns typically generated during locomotion, the horizontal system (HS) cells, encoded unambiguous quantitative information about the fly's walking behavior independently of vision. Angular and translational velocity signals were integrated with a behavioral-state signal and generated direction-selective and speed-sensitive graded changes in the membrane potential of these non-spiking cells. The nonvisual direction selectivity of HS cells cooperated with their visual selectivity only when the visual input matched that expected from the fly's movements, thereby revealing a circuit for internally monitoring voluntary walking. Furthermore, given that HS cells promoted leg-based turning, the activity of these cells could be used to control forward walking.
