Neurobiological and metabolic basis of motivation and effort-based decision-making - A human 1H-MRS, fMRI and machine learning study
Motivation is a multifaceted phenomenon that we explore within the framework of decision-making. Through this cognitive process, actions are directed towards specific goals by performing a trade-off between the cost and benefit of an action. The dorsomedia ...
EPFL2024Neuronal correlates of goal-directed sensorimotor transformation in sensory, motor and higher-order cortical areas
An important function of the brain is to interpret incoming sensory information from the outside world to guide adaptive behavior. Understanding how and where sensory information is transformed into motor commands in a context- and learning-dependent manne ...
EPFL2023Noninvasive deep brain stimulation to modulate human behavior by means of transcranial temporal interference electrical stimulation
All functions we use in our everyday life depend on a complex interplay between both cortical and subcortical brain areas, communicating in between each others. When a region is affected by either an accident, aging or neurodegenerative diseases, the whole ...
EPFL2023Exchange options with stochastic liquidity risk
In this article, we account for the liquidity risk in the underlying assets when pricing European exchange options, which has not been considered in the literature. An Ornstein-Uhlenbeck process with the mean -reversion property is selected to model the ma ...
PERGAMON-ELSEVIER SCIENCE LTD2023Determining patterns of post-stroke motor recovery through longitudinal multimodal MRI: A step towards patient stratification
Motivated by the need for a better understanding of post-stroke recovery and new biomarkers to improve stroke patient stratification and outcomes, this thesis investigated structure-function coupling and its role in post-stroke recovery. Furthermore, in or ...
EPFL2022Illiquidity and Higher Cumulants
Semyon Malamud, Alberto Mokak Teguia
We characterize the unique equilibrium in an economy populated by strategic CARA investors who trade multiple risky assets with arbitrarily distributed payoffs. We use our explicit solution to study the joint behavior of illiquidity of option contracts. Op ...
OXFORD UNIV PRESS INC2022Covariance Estimation for Random Surfaces beyond Separability
This thesis focuses on non-parametric covariance estimation for random surfaces, i.e.~functional data on a two-dimensional domain. Non-parametric covariance estimation lies at the heart of functional data analysis, andconsiderations of statistical and comp ...
EPFL2022Skew-Brownian motion and pricing European exchange options br
This article derives a closed-form pricing formula for European exchange options under a non-Gaussianframework for the underlying assets, intending to resolve mispricing associated with a geometric Brownianmotion. The dynamics of each of the two correlated ...
ELSEVIER SCIENCE INC2022Cortical ensembles orchestrate social competition through hypothalamic outputs
Most social species self-organize into dominance hierarchies(1,2), which decreases aggression and conserves energy(3,4), but it is not clear how individuals know their social rank. We have only begun to learn how the brain represents social rank(5-9) and g ...
2022The perspectives of mapping and monitoring of the sense of self in neurosurgical patients
Olaf Blanke, Bruno Herbelin, Hyeongdong Park, Sophie Jacqueline Andrée Betka, Pavo Orepic, Sixto Luis Alcoba Banqueri, Giannina Rita Iannotti
Surgical treatment of tumors, epileptic foci or of vascular origin, requires a detailed individual pre-surgical workup and intra-operative surveillance of brain functions to minimize the risk of post-surgical neurological deficits and decline of quality of ...
