Summary Successful social interactions require social decision making, the ability to guide our actions in line with the goals and expectations of the people around us. Disordered social decision making – e.g., associated with criminal activity or psychiatric illnesses – poses significant financial and personal challenges to society. However, the brain mechanisms that enable us to control our social behavior are far from being understood. Here I will take decisive steps towards a causal understanding of these mechanisms by elucidating the role of functional interactions in the brain networks responsible for steering strategic, prosocial, and norm-compliant behavior. I will employ a unique multi-method approach that integrates computational modeling of social decisions with new combinations of multimodal neuroimaging and brain stimulation methods. Using EEG-fMRI, I will first identify spatio-temporal patterns of functional interactions between brain areas that correlate with social decision processes as identified by computational modeling of behavior in different economic games. In combined brain stimulation-fMRI studies, I will then attempt to affect – and in fact enhance – these social decision-making processes by modulating the identified brain network patterns with novel, targeted brain stimulation protocols and measuring the resulting effects on behavior and brain activity. Finally, I will examine whether the identified brain network mechanisms are indeed related to disturbed social decisions in two psychiatric illnesses characterized by maladaptive social behavior (post-traumatic stress disorder and autism spectrum disorder). My proposed work plan will generate a causal understanding of the brain network mechanisms that allow humans to control their social decisions, thereby elucidating a biological basis for individual differences in social behavior and paving the way for new perspectives on how disordered social behavior may be identified and hopefully remedied.

Project acronym ChangeBehavNeuro
Project Novel Mechanism of Behavioural Change
Researcher (PI) Tom SCHONBERG
Host Institution (HI) TEL AVIV UNIVERSITY
Call Details Starting Grant (StG), SH4, ERC-2016-STG
Summary Understanding how values of different options that lead to choice are represented in the brain is a basic scientific question with far reaching implications. I recently showed that by the mere-association of a cue and a button press we could influence preferences of snack food items up to two months following a single training session lasting less than an hour. This novel behavioural change manipulation cannot be explained by any of the current learning theories, as external reinforcement was not used in the process, nor was the context of the decision changed. Current choice theories focus on goal directed behaviours where the value of the outcome guides choice, versus habit-based behaviours where an action is repeated up to the point that the value of the outcome no longer guides choice. However, in this novel task training via the involvement of low-level visual, auditory and motor mechanisms influenced high-level choice behaviour. Thus, the far-reaching goal of this project is to study the mechanism, by which low-level sensory, perceptual and motor neural processes underlie value representation and change in the human brain even in the absence of external reinforcement. I will use behavioural, eye-gaze and functional MRI experiments to test how low-level features influence the neural representation of value. I will then test how they interact with the known striatal representation of reinforced behavioural change, which has been the main focus of research thus far. Finally, I will address the basic question of dynamic neural plasticity and if neural signatures during training predict long term success of sustained behavioural change. This research aims at a paradigmatic shift in the field of learning and decision-making, leading to the development of novel interventions with potential societal impact of helping those suffering from health-injuring behaviours such as addictions, eating or mood disorders, all in need of a long lasting behavioural change.

Project acronym CYCLODE
Project Cyclical and Linear Timing Modes in Development
Researcher (PI) Helge GROSSHANS
Host Institution (HI) FRIEDRICH MIESCHER INSTITUTE FOR BIOMEDICAL RESEARCH FONDATION
Call Details Advanced Grant (AdG), LS3, ERC-2016-ADG
Summary Organismal development requires proper timing of events such as cell fate choices, but the mechanisms that control temporal patterning remain poorly understood. In particular, we know little of the cyclical timers, or ‘clocks’, that control recurring events such as vertebrate segmentation or nematode molting. Furthermore, it is unknown how cyclical timers are coordinated with the global, or linear, timing of development, e.g. to ensure an appropriate number of cyclical repeats. We propose to elucidate the components, wiring, and properties of a prototypic developmental clock by studying developmental timing in the roundworm C. elegans. We build on our recent discovery that nearly 20% of the worm’s transcriptome oscillates during larval development – an apparent manifestation of a clock that times the various recurring events that encompass each larval stage. Our aims are i) to identify components of this clock using genetic screens, ii) to gain insight into the system’s architecture and properties by employing specific perturbations such as food deprivation, and iii) to understand the coupling of this cyclic clock to the linear heterochronic timer through genetic manipulations. To achieve our ambitious goals, we will develop tools for mRNA sequencing of individual worms and for their developmental tracking and microchamber-based imaging. These important advances will increase temporal resolution, enhance signal-to-noise ratio, and achieve live tracking of oscillations in vivo. Our combination of genetic, genomic, imaging, and computational approaches will provide a detailed understanding of this clock, and biological timing mechanisms in general. As heterochronic genes and rhythmic gene expression are also important for controlling stem cell fates, we foresee that the results gained will additionally reveal regulatory mechanisms of stem cells, thus advancing our fundamental understanding of animal development and future applications in regenerative medicine.

Project acronym DEVOMIND
Project How do infants mentalize? Bringing a neuroimaging approach to the puzzle of early mindreading.
Researcher (PI) Victoria SOUTHGATE
Host Institution (HI) KOBENHAVNS UNIVERSITET
Call Details Consolidator Grant (CoG), SH4, ERC-2016-COG
Summary Human social interaction and learning depends on making the right inferences about other people’s thoughts, a process commonly called mentalizing, or Theory of Mind, a cognitive achievement which several decades of research concluded was reached at around age 4. The last 10 years has radically changed this view, and innovative new paradigms suggest that even preverbal infants can think about others’ minds. This new developmental data has created arguably one of the biggest puzzles in the history of developmental science: How can infants be mentalizing when years of research have shown that a) pre-schoolers fail at mentalizing tasks and b) mentalizing depends on the development of cognitive control, language, and brain maturation? The key issue is whether behaviour that looks like infant mentalizing really is mentalizing, or might infants’ success belie alternative processes? The most powerful strategy for resolving this puzzle is to look to brain activity. By applying the same methods and paradigms across infancy and early childhood, DEVOMIND will investigate whether infants’ success on mentalizing tasks recruits the same network of brain regions, and neural processes, that we know are involved in success in older children and adults. In the second half of the project, we will use our neural indicators of mentalizing to test a completely novel hypothesis in which infants’ success is possible because they have a limited ability to distinguish self from other. Although novel, this hypothesis deserves to be tested because it has the potential to explain both infants’ success and preschoolers’ failures under a single, unified theory. By bringing a neuroimaging approach to the puzzle of early mentalizing, DEVOMIND will allow us to move beyond the current impasse, and to generate a new theory of Theory of Mind.

Project acronym EMODHEBREW
Project The emergence of Modern Hebrew as a case-study of linguistic discontinuity
Researcher (PI) Edit Doron
Host Institution (HI) THE HEBREW UNIVERSITY OF JERUSALEM
Call Details Advanced Grant (AdG), SH4, ERC-2016-ADG
Summary The pioneering enterprise I propose is the study of a particular type of linguistic discontinuity – language revival – inspired by the revival of Hebrew at the end of the 19th century. The historical and sociocultural dimensions the revival have been studied before, but not its linguistic dimensions. My main aim is to construct a model of the linguistic factors which have shaped the revival of Hebrew. I expect this model to provide clues for the understanding of the process of language revival in general. For a language to be revived, a new grammar must be created by its native speakers. I hypothesize that the new grammar is formed by some of the general principles which also govern other better known cases of linguistic discontinuity (creoles, mixed languages, emergent sign languages etc.). The model I will develop will lay the foundation for a new subfield within the study of discontinuity – the study of language revival. I will start with careful work of documenting the development of the grammar of Modern Hebrew, in particular its syntax, something which has not been done systematically before. One product of the project will be a linguistic application for the documentation and annotation of the novel syntactic constructions of Modern Hebrew, their sources in previous stages of Hebrew and in the languages with which Modern Hebrew was in contact at the time of the revival, and the development of these constructions since the beginning of the revival until the present time. The linguistic application will be made available on the web for other linguists to use and to contribute to. The institution of an expanding data-base of the syntactic innovations of Modern Hebrew which comprises both documentation/ annotation and theoretical modeling which could be applied to other languages makes this an extremely ambitious proposal with potentially wide-reaching ramifications for the revival and revitalization of the languages of ethno-linguistic minorities world wide.
