Frontiers Research Topic "Discrimination of Genuine and Posed Facial Expressions of Emotion"

by Jian Liu

Call for Papers: Frontiers Research Topic "Discrimination of Genuine and Posed Facial Expressions of Emotion" More information: https://www.frontiersin.org/research-topics/9221/discrimination-of-genuine-… About this Research Topic Facial expressions demonstrate one emotional states in interpersonal situations. Evidence shows that part of the facial display reflects the emotional experience that is literally felt by the expresser. Interestingly, human beings are capable of identifying facial expressions of the felt emotions as a form of intentional deception to conduct social interaction and to stage displays that have the support of others. Staged or posed facial expressions implement an emotion that an expresser intends to convey, where genuine expressions are considered as the companion of spontaneous emotional expressions. The ability to differentiate genuine displays of emotional experience from posed ones is very important for dealing with day-to-day social interactions. Recent work has been conducted on whether or not people can distinguish between posed and genuine displays of emotion. In spite of few studies to investigate this ability, most prior research suggests that people have the ability to judge genuine and posed facial displays. Unfortunately, previous research has suffered from two major shortcomings: (1) the mixture of staged and genuine displays due to the lack of accounting for possible effects of intentional manipulation, and (2) struggling to consider dynamic aspects when people prepare facial stimuli for experimental investigation. This Research Topic encourages the submission of theoretical and experimental perspectives to broaden understanding of the importance of the discrimination of genuine and posed facial expressions of emotion. These may be new theoretical approaches, those from other disciplines of psychology not usually utilized within the discrimination of genuine and staged emotion identification or new theories and designs. We seek articles that present new hypotheses, concepts, experimental observations, and theories or models; demonstrate how theories adapted from other disciplines may be utilized for emotion identification or provide recommendations to improve current models or theories to enhance their capacity. We look for papers that may combine critical analysis of current models, synthesis of early empirical work by single- or multi-modality analysis (e.g. video, ECG, EEG, fMRI, and single cells in humans and/or animals), and explore the potential for their development applied to the context of emotion recognition. Submissions of systematic reviews and meta-analysis should discuss and promote comprehensive approaches to update and evolve concepts, hypotheses, and theories with potential applications in the community. Keywords: face expression, discrimination, genuine, posed, emotion Guest editors: Huiyu Zhou, Department of Informatics, University of Leicester, United Kingdom.

2 years postdoc position in reinforcement learning-based modeling of animal behavior

by david robbe

Dear Colleagues, Please find below an announcement for a postdoc position in Marseille (France) to develop reinforcement learning-based models of animal behavior. The Turing Centre for Living Systems in Marseille seeks applicants for a postdoc position in computational neuroscience/robotics under the joint supervision of David Robbe and Christophe Eloy. The initial appointment will be for 2 years. The goal of this project is to understand, at an algorithmic level, how animals learn to develop adaptive behavior by trial-and-error interaction with their environment. We propose an interdisciplinary approach combining behavioral experiments in rats and the development of an "artificial" agent facing challenges similar to those experienced by the rats. The experimental data (already available) show that rats challenged in a time estimation task converged progressively toward a conserved embodied strategy (Rueda-Orozco and Robbe, Nature Neuroscience, 2015). Key determinants of that strategy have been isolated experimentally, by altering task rules and environment and quantifying how these alterations affect animal performance. Learning theoretical models will be based on reinforcement learning and more recent developments coming from artificial intelligence (deep learning). The main task of the project will be to develop computational model and therefore we expect the candidates to have a solid background in the gerenal field of machine learning. The successful applicant will work in close collaboration with experimentalists and robotic engineers. We are therefore looking for an enthusiastic applicant with excellent communication skills and a track record in interdisciplinary collaborative environments Deadline for application: 1st of December 2018 (late application will be considered until the end of the year) More information and application.<http://centuri-livingsystems.org/pdp2018-11/>http://centuri-livingsystems.org/pdp2018-11/ -- David Robbe, PhD Neural Bases of Sensorimotor learning Institut de Neurobiologie de la Méditerranée (INMED) INSERM-UMR1249 163, avenue de Luminy.

PhD studentship, University of Exeter

by Goodfellow, Marc

A fully funded studentship is available to work with Dr. Marc Goodfellow (University of Exeter, UK) and Prof. George Augustine (NTU, Singapore). The deadline for applications is 31st January 2019. Healthy brain function is mediated by the coordination of neuronal activity - both locally and across different brain regions - giving rise to large-scale brain dynamics. These dynamics are measured using a variety of techniques, for example magneto-/electro-encephalography or functional MRI in humans, or by fluorescence-based imaging of voltage- or calcium-sensitive indicators in animal models in vivo. Uncovering the nature and mechanisms of large-scale brain dynamics at rest, or during sensory processing, remains a fundamental challenge in neuroscience. In addition to basic insight, improving our understanding of healthy brain dynamics will help us elucidate reasons why abnormal dynamics occur, for example in neurological or neuropsychiatric disorders. This studentship will develop a novel program of interdisciplinary research across in vivo (mouse) experimentation and mathematical modelling. The overall aim is to construct and validate mathematical models of large-scale brain dynamics that are able to explain the spontaneous activity of the rodent brain in vivo. The student will train in optogenetic technologies and in vivo imaging, as well as mathematical model development, multi-variate time series analysis and parameter fitting tools, thus placing them at the forefront of interdisciplinary neuroscience. In a first step, targeted optogenetic stimuli will be combined with voltage sensitive dye imaging in awake mice to probe the response of brain tissue to excitatory and inhibitory afferent stimuli. Neural mass models will be fit to these data, using machine learning approaches (for example random forests). This information will be compiled into a predictive model of cortical dynamics and tested against experimental recordings of spontaneous activity. The studentship is part of a joint program between The University of Exeter (UoE) and Nanyang Technological University (NTU), Singapore. They are offering six fully funded postgraduate studentships to undertake collaborative research projects at the two institutions, leading to PhD degrees (split-site) to be conferred either by the UoE or NTU. Students pursuing these postgraduate research projects will benefit from the unique opportunity to conduct their research at both institutions. Students will be registered at one or other institution, where they will be based for the majority of their time, but will spend at least 12 and not more than 18 months at the partner institution over the duration of the programme. The frequency and length of stays at each institution will be agreed with successful candidates prior to offers being made. All six projects are advertised concurrently at both institutions and three will be allocated to each institution after the deadline has passed, based on a collaborative decision made between the UoE and NTU. The final decision on the successful applicant for each project will be made by the institution hosting the project. Project allocation will be based on the applicant's best fit to a project, following a review of applications submitted to each institution. Applications to undertake the projects at the UoE and NTU are open to all nationalities. The programme start dates are August 2019 for NTU and September 2019 for UoE The home institution will determine the regulations that will apply to the successful applicant. The student's main supervisor will be based at the home institution. For further information and to register interest, please contact Dr. Marc Goodfellow (m.goodfellow(a)exeter.ac.uk) To apply and for further details, please see http://www.exeter.ac.uk/studying/funding/award/?id=3058

This three-years fellowship is funded by the ANR grant (Agence National de la Recherche) “ERMUNDY (Exact Reduction of Multiscale Neural Dynamics)”. In the context of this project we will develop computational multi-scale models of cortical oscillatory dynamics (multiple frequencies, cross-frequency coupling…) and of its control via stimulation. The used models (from the regional to the whole-brain level) will be constrained by realistic information on the phase response properties of actual neural populations, which will be inferred from both extra-cranial (TMS) and intra-cranial (sEEG) stimulation data, acquired in house at AMU. Interactions with other researchers will take place as well, including experimentalists located in AMU, and theorists at Cergy-Pontoise University (Alessandro Torcini) and Ecole Normale Supérieure in Paris (Boris Gutkin). The PhD fellow will participate to both experimental data analysis (extraction of Phase Response Curves, functional connectivity analyses…) and model design and simulation. The successful candidate will integrate the Theoretical Neuroscience Group at the Institute for Systems Neuroscience (INS), located on the same campus of the Timone University hospital (AP-HM). The integrative and clinical neuroscience community in Marseille is among the most lively in Europe and Marseille is a vibrating city, with wonderful natural surroundings and home to the largest French-speaking university in the world, with an emphasis on interdisciplinary studies. Salary (~1.4k euros net, after all taxes and full social security coverage) is defined according to French national guidelines and cannot be negotiated. Interested candidates should send a cv, a brief description of qualifications and research interests and the name of one or two reference contacts to: Demian Battaglia demian.battaglia(a)univ-amu.fr Feel free to inquire for further information. Applications from under-represented categories in STEM sciences are welcome and supported.
