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.

Abstract/Results: ABSTRACT
Experiments in anesthetized, immobile animals have contributed to the classical view that sensory and motor functions in the brain are separated processes. However, under natural conditions, the nervous system and the body of a moving animal interact continuously, and it is from this interaction that neural circuits in the brain form an internal representation of the sensory world. We move our head to detect and localize the source of a sound, we move our eyes to scan a visual scene; likewise, tactile sensation is based on our body’s movement, and olfaction occurs in the context of sniffing. Sensory and motor components of a sensory modality are intimately connected to each other during an active process. How this relation is implemented across sensorimotor circuits, and how motor–sensory coordination improves sensation, are questions that still remain unclear. Recent technological advances have made possible to record neural activity from sensory areas while animals walk or fly—behavioral conditions in which sensation most frequently happens. From these studies, performed both in insects and mammals, it has become apparent that the neural dynamics of primary sensory areas are readily influenced by ongoing locomotion. In this chapter, we discuss work dissecting different components of the locomotion-dependent modulations, focusing on visual circuits in flies and mice. The presence of these locomotive-related signals in early visual centers strongly suggests that motor–sensory coordination is dynamic, diverse, and adaptable to the behavioral situation of the animal.

Abstract/Results: ABSTRACT:
A substantial portion of our sensory experience happens during active behaviors such as walking around or paying attention. How do sensory systems work during such behaviors? Neural processing in sensory systems can be shaped by behavior in multiple ways ranging from a modulation of responsiveness or sharpening of tuning to a dynamic change of response properties or functional connectivity. Here, we review recent findings on the modulation of sensory processing during active behaviors in different systems: insect vision, rodent thalamus, and rodent sensory cortices. We discuss the circuit-level mechanisms that might lead to these modulations and their potential role in sensory function. Finally, we highlight the open questions and future perspectives of this exciting new field.

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
Course control is critical for the acquisition of spatial information during exploration and navigation, and it is thought to rely on neural circuits that process locomotive-related multimodal signals. However, which circuits underlie this control, and how multimodal information contributes to the control system are questions poorly understood. We used Virtual Reality to examine the role of self-generated visual signals (visual feedback) on the control of exploratory walking in flies. Exploratory flies display two distinct motor contexts, characterized by low speed and fast rotations, or by high speed and slow rotations, respectively. Flies use visual feedback to control body rotations, but in a motor-context specific manner, primarily when walking at high speed. Different populations of visual motion-sensitive cells estimate body rotations via congruent, multimodal inputs, and drive compensatory rotations. However, their effective contribution to course control is dynamically tuned by a speed-related signal. Our data identifies visual networks with a multimodal circuit mechanism for adaptive course control and suggests models for how visual feedback is combined with internal signals to guide exploratory course control.
