The annual Barcelona Computational, Cognitive and Systems Neuroscience (BARCCSYN) meeting is about bringing together researchers from computational, systems and cognitive neuroscience. Our goal is to provide a forum for lively discussion and promote active collaboration between Barcelona-based research groups, especially between theorists and experimentalists.
This is the 12th annual Barccsyn conference.  The conference will be held on May 30 and 31, 2024, at the Institut d’Estudis Catalans.  Each day we will have 8-10 brief oral presentations from local researchers, a poster session and two longer keynote lectures from two renowned researchers from abroad.
BARCCSYN 2024 is the second edition organised by the section Neurociència computacional i de sistemes that belongs to the Societat Catalana de Biologia and Societat Catalana de Matemàtiques.

Does efficient value synthesis in the OFC explain how risk attitude adapts to the range of risk prospects?

Jean Daunizeau

Institut du Cerveau, INSERM
Why do we do what we do? Motivation can be defined as the process that forms goals and transforms them into action. A goal can be reduced to a situation with anticipated positive (hedonic) value: earning money, performing well, being loved, etc… However, goal achievement typically involves investing effort, which is aversive. Hence, goal-directed behaviour necessarily trades incentive values with effort costs. This raises three basic questions we concern our research with: how does the brain computes net value? How do psychological and/or biological constraints influence value computations? How do value computations determine behavioural outputs? Understanding the mechanics of motivational processes from the multimodal observation of brain activity and behaviour thus requires relating processes of value computation to the neurobiology of the underlying brain networks in a quantitative manner. To do this, I rely on formal mathematical theories that I borrow from diverse academic fields, such as Artificial Intelligence, Control Engineering and Statistical Physics.



Is irrational behavior the incidental outcome of biological constraints imposed on neural information processing? Recent studies indicate that orbitofrontal neurons encode decision value in relative terms, i.e. value signals in OFC neurons are normalized with respect to the context. Value-based decisions may thus exhibit irrational context-dependence effects. A candidate explanation is “efficient coding”: OFC neurons may minimize information loss by adapting their (bounded) output firing properties to the recent value range. This is seducing, because it suggests that relative value coding is the brain’s best attempt to mitigate its own hard-wired biological constraints. However, whether the behavioral implications of this scenario are met, how it generalizes to realistic situations in which OFC neurons construct value from multiple decision-relevant attributes – which we coin “value synthesis” – and what its neurophysiological bases are, is unclear. Here, we approach these issues from a neurocomputational perspective. First, we show how artificial neural networks can self-organize through neo-hebbian rewiring processes to operate efficient value synthesis, i.e. value synthesis that is robust to neural perturbations. Importantly, we show that such mechanism predicts that value synthesis progressively adapts to the experienced range of decision attributes. In turn, the relative weight of decision-relevant attributes onto value-based decisions is inversely proportional to their respective range. We then test these predictions on two open fMRI datasets from the initiative, where people have to integrate prospective gains and losses to decide whether to gamble or not. We show that peoples’ risk attitudes critically depend on the range of gain/loss prospects they are exposed to (in the absence of feedback). We also show that, when adjusted to explain peoples’ irrational choices, efficient value synthesis in neural networks predicts (out-of-sample) the representational content of multivariate fMRI activity patterns in the OFC. Our results suggest that some forms of irrational behavior may be the corollary consequence of self-organization in OFC networks that operate efficient value synthesis.

Studying urgency and arousal during decision making in humans

Julie Duqué

Université Catholique de Louvain

Full Professor, Head of the CoActions Lab. Our research broadly explores a range of questions pertaining to the cognitive neuroscience of human behavior. We conduct experiments to explore the interaction between cognition and action in neurologically healthy and impaired individuals. We use a variety of techniques to characterize the functional role of different parts of the motor pathways including transcranial magnetic stimulation (TMS), functional and structural magnetic resonance imaging (MRI) and electroencephalography (EEG). Development of a closed-loop TMS-EEG setup will allow us to explore the role of sensorimotor neural oscillatory activity on motor output.



Humans and other animals make a wide range of decisions throughout their daily lives, with varying degrees of speed and precision. This variability is not only due to the amount of evidence based on which one makes decisions but also to the sense of urgency and the level of arousal that can vary between and within individuals, from one situation to another. My talk will focus on the work we have been doing lately to better understand mechanisms underlying urgency and the contribution of arousal during decision making. It will be divided into two parts. In the first section, I will describe a study in which we investigated the impact of urgency on motor neural activity, studied using transcranial magnetic stimulation (TMS) over primary motor cortex (M1) during decision making in an index finger variant of the Tokens task, originally developed for studies of urgency in non-human primates by D. Thura and P. Cisek. Then, in the second part of my talk, I will turn to a recent investigation of the role of the arousal system in decision making. Interestingly, it is possible to causally address the role of arousal in humans by means of transcutaneous Vagus Nerve Stimulation (tVNS), which employs electrical stimulation targeting the auricular branch of the vagus nerve to stimulate non-invasively the locus coeruleus noradrenergic system, one major source of arousal in the brain. I will present new behavioural data collected in the random dot motion discrimination task with 4 second-trains of online tVNS (compared to sham) and pupillometry.
