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:
We are constantly faced with the trade-off between exploiting past actions with known outcomes and exploring novel actions whose outcomes may be better. This exploration-exploitation balance is thought to be influenced by dopaminergic neurons of the substantia nigra pars compacta (SNc) and noradrenergic neurons of the locus coeruleus (LC). However, little is known about SNc and LC network dynamics during exploration. We aimed to characterize dopaminergic and noradrenergic signaling during these distinct behavioral states. We developed a novel behavioral paradigm in mice to investigate exploratory and exploitative behavioural states. Mice were presented with three equidistant nose poke ports and had to explore the environment to discover a sequence of three nose pokes that was rewarded. We then performed calcium imaging in either the SNc or LC of freely behaving mice during performance of this task. Actions were variable as mice explored to find the rewarded sequence, but became stable as they learned to exploit the rewarded sequence. When the rewarded sequence was changed, mice returned to a more variable state. Dopaminergic networks expressed higher levels of sustained activity when mice were exploiting relative to exploring, and these differences could not be accounted for by low-level differences in reward occurrence. Conversely, noradrenergic networks exhibited higher levels of sustained activity when mice were exploring relative to exploiting. These experiments suggest that exploitation is associated with higher sustained levels of dopaminergic activity and lower sustained levels or noradrenergic activity, with potentially important consequences for downstream circuits.

More than just a "Motor": Recent surprises from the frontal cortex
Publication year: 2018

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6209835/
Abstract/Results: ABSTRACT
Motor and premotor cortices are crucial for the control of movements. However, we still know little about how these areas contribute to higher-order motor control, such as deciding which movements to make and when to make them. Here we focus on rodent studies and review recent findings, which suggest that-in addition to motor control-neurons in motor cortices play a role in sensory integration, behavioral strategizing, working memory, and decision-making. We suggest that these seemingly disparate functions may subserve an evolutionarily conserved role in sensorimotor cognition and that further study of rodent motor cortices could make a major contribution to our understanding of the evolution and function of the mammalian frontal cortex.

Dichotomous dopaminergic and noradrenergic neural states mediate distinct aspects of exploitative behavioral states
Publication year: 2021
URL:
https://advances.sciencemag.org/content/7/30/eabh2059
Abstract/Results: ABSTRACT:
The balance between exploiting known actions and exploring alternatives is critical for survival and hypothesized to rely on shifts in neuromodulation. We developed a behavioral paradigm to capture exploitative and exploratory states and imaged calcium dynamics in genetically identified dopaminergic and noradrenergic neurons. During exploitative states, characterized by motivated repetition of the same action choice, dopamine neurons in SNc encoding movement vigor showed sustained elevation of basal activity that lasted many seconds. This sustained activity emerged from longer positive responses, which accumulated during exploitative action-reward bouts, and hysteretic dynamics. Conversely, noradrenergic neurons in LC showed sustained inhibition of basal activity due to the accumulation of longer negative responses in LC. Chemogenetic manipulation of these sustained dynamics revealed that dopaminergic activity mediates action drive, whereas noradrenergic activity modulates choice diversity. These data uncover the emergence of sustained neural states in dopaminergic and noradrenergic networks that mediate dissociable aspects of exploitative bouts.

Final report - A swing between the inner and the outer worlds: Exploring the function of the frontal aslant tract with transcranial magnetic stimulation
Publication year: 2024
Abstract/Results:
ABSTRACT:
Background
Humans interacting with the world choose between two mutually incompatible strategies: either building an internal representation of the future temporal events and acting by predicting what will happen or waiting for external events to happen and then reacting to them. The two strategies could interact by means of the white matter bundle “frontal aslant tract” (FAT), connecting the superior frontal gyrus (SFG) to the inferior frontal gyrus (IFG)..
Aims
To understand the role of the IFG and SFG terminations of the FAT, in the light of their connectivity. To show homologies between the SFG and IFG regions connected by FAT fibers, with internally-driven actions in the SFG and externally-driven actions in the IFG.
Method
We used tractography-guided transcranial magnetic stimulation (TMS) to interfere transiently with local neural process in the SFG and IFG, at both terminations of the FAT, but at 3 different positions along the caudal-cranial axis, during different tasks: a) an implicit strategic choice between internally-timed and externally-driven action strategies and b) spontaneous production of rhythmic movements.
Results
Stimulation of the SFG produced biases towards internal strategies and stimulation of the IFG produced biases towards external strategies. SFG stimulation interfered also with internally-paced actions. The control of strategy was localized more anteriorly compared to the control of action timing.
Conclusions
Our data confirm that the FAT mediates the interaction between internally-driven actions, represented in the SFG and externally-driven actions represented in the IFG. The mid-portion of the FAT controls action selection. The posterior part produces action plans for action execution.
