Chapalain, Thomas. "Investigating the representation of numerosity in humans and convolutional neural networks using high-variability photorealistic stimuli." Electronic Thesis or Diss., université Paris-Saclay, 2025. http://www.theses.fr/2025UPASG020.
Повний текст джерелаThe ability to rapidly estimate the number of items in a scene without explicit counting, known as visual number sense, has been the focus of extensive research. Experimental studies and computational models have sought to uncover the mechanisms that enable the human brain to extract numerosity at a glance. Recent advances in imaging techniques, including ultra-high-field functional MRI (fMRI), multivariate pattern analysis, and population receptive field (pRF) modeling, have provided deeper insights into how numerical information is encoded in the brain.These studies have highlighted the involvement of higher-order regions, such as the frontal and parietal cortices, but also lower-level areas, in numerical perception. Most research on numerosity perception has relied on simplified visual stimuli, such as binary dot arrays. While useful, these stimuli fail to capture the complexity of real-world visual environments and present a special case where numerosity is tightly correlated with some low-level statistics of the visual input. This raises questions about ecological validity, and about the extent to which previous findings reflected the discrete number of items per se as opposed to correlated low-level factors. In this thesis, we developed a synthetic photorealistic stimulus dataset to address these limitations, introducing high variability in the characteristics of both objects and scenes while maintaining precise experimental control. This dataset allows for the study of numerosity perception in contexts closer to natural images. Using this new dataset of photorealistic renderings of 3D objects embedded in diverse background scenes, our analyses demonstrated that deep convolutional neural networks (CNNs) optimized for object recognition could encode numerical information with robustness to diverse objects and scenes in distributed activity patterns of their higher convolutional layers. Conversely, untrained networks failed to discriminate numerical content across changes in those other high-level visual properties and mainly encoded low-level summary statistics.These findings suggest that untrained models may not truly encode discrete numerosity and emphasize the importance of using complex stimuli to probe the neural mechanisms of visual number sense. Given the role of CNNs' as models of the ventral visual stream, this research motivates further investigation of how numerical information is represented in the brain beyond commonly studied dorsal-parietal areas. Therefore, in an independent 7T fMRI study, we recorded brain activity of both ventral and dorsal visual pathways while participants viewed and attended to the numerical content of similar synthetic photorealistic stimuli.This experimental paradigm enabled us to disentangle numerical information from correlated visual statistics, allowing for the examination of their distinct contributions to brain activity. Our findings revealed that lateral occipital areas, commonly linked to object recognition, could simultaneously represent numerical and object-related information. Additionally, dorsal parietal regions demonstrated a specialized role in encoding numerical information beyond basic visual features. In contrast, low-level visual statistics primarily influenced early visual and higher-level ventral temporal areas, with minimal impact on higher-order dorsal regions. These findings illustrate a hierarchical organization in visual processing, transitioning from encoding of low-level features to more invariant representations of objects and numerosity in higher-level brain areas. Our work underscores the abstract nature of numerosity representations, advancing our understanding of numerical cognition under more realistic visual conditions

Повний текст джерелаHow does sense emerges in the visual system? In this thesis we will be focused on the visual system of human and non-human primates and their large capacity of extract and represent visual information. We studied several levels of visual representations from those related to the extraction of coarse visual features to the emergence of conscious visual representations. This manuscript presents six works in which we explored: (1) the visual features necessary to perform ultra-rapid visual categorization in monkeys and humans using psychophysics, (2) the spatio-temporal dynamics of visual attention in humans using psychophysics, (3) the neural correlates of high-level visual representations using EEG tanks to the development of an innovative technique called SWIFT, (4) the neural correlates of visual consciousness under binocular rivalry using EEG, (5) the synchrony of brain signals as a function of conscious recognition using intracranial electrodes implanted in epileptic patients and (6) the neural correlates associated with conscious perception in monkeys using intracranial electrodes. The results of these works allowed outlining a tentative model of visual perception aimed to dissociate attention and consciousness

Повний текст джерелаThis thesis aims at modelling and solving optimization problems related to the management of one-way-electric-car-sharing systems, where users can take a car from a station, use it, and then return it to another station. This generally leads to an imbalanced distribution of cars, with some full stations and other empty ones. A solution to this problem, implemented by car-sharing operators, is to employ staff agents to move cars as needed. However, identifying this need is a non-trivial optimization problem, especially since the system may be more constrained when the vehicles used are electric, which generates battery recharging and autonomy constraints. The global optimization problem addressed is then divided into two sub-problems. The first one is assigning the cars to customers, as well as their routing; it is denoted by ROCSP (Recharging OneWay Car Sharing Problem). The second problem involves agents planning and routing; it is denoted by ESRP (Employee Scheduling Routing Problem). 1. For the ROCSP, we propose two Mixed-integer linear programming (MILP) modelizations of the problem: One based on flows and the other based on paths. This means that the two models include the battery-recharging constraints in two different ways. As the exact resolution through the MILP models is quite expensive in terms of computational time and is not adapted for the resolution of real-size car-sharing instances, we introduce heuristics that enable the optimization of cars-redistribution and service management of the service within a reasonable amount of time. These heuristics allows the calculation of the number of cars and the various redistribution operations to be performed on a given day. 2. For the ESRP, this second problem is also addressed with MILP models for the exact resolution, and some heuristics are suggested for an approximate resolution. This process has reasonable calculation time and aims at finding the minimum number of agents to perform the necessary relocation operations that stem from the first problem, namely, the ROCSP. Once the ROCSP and ESRP solved in their static versions, we then focus on the ROCSP by exploring another variant of the problem : ROCSP with dynamic reservation. We also suggest to explore a new concept : Auto-CoPartage, which is a hybridization of car-sharing and carpooling. The stated algorithms are validated on the Auto Bleue electrical vehicles fleet in the network of the city of Nice, essentially by relying on flow generation models to estimate the demand, but also using other instances that we have generated for other cities. All the data are handled using a Geographical Information System

Повний текст джерелаVision in honeybees has been extensively studied at the behavioral level by training free-flying insects to choose visual targets rewarded with sucrose solution, and, to a lesser degree, at the physiological level using intracellular electrophysiological recordings of single neurons in different areas of the visual circuits of the bee brain. However, our knowledge of visual processing in honeybees is still limited by the lack of: 1- conditioning protocols for studying visual learning and memory in harnessed animals under controlled laboratory conditions; 2- anatomical and physiological characterizations of visual neuropils in the central brain; and 3- techniques for performing functional studies of visual processing at the neuronal circuit level. In the present work, we aimed at filling these gaps by providing a multilevel study of visual processing in harnessed bees. We aimed at developing novel appetitive and aversive conditioning protocols for studying visual learning and memory in harnessed bees. In an appetitive framework, we showed that intact harnessed bees are not capable of learning a direct association between color and sucrose. For reasons so far unknown, antennae ablation is necessary for harnessed bees to acquire such an elemental color-sucrose association. Despite this incapacity, intact bees are able to solve a non-elemental bimodal discrimination in which colors act as modulators of appetitive olfactory learning. We therefore provide the first controlled demonstration of bimodal (color-odor) occasion setting in harnessed honeybees. In an aversive framework, we established a new conditioning protocol in which harnessed bees learn aversive associations between visual cues and an electric shock. We showed that bees with intact antennae learn to discriminate punished from non-punished visual stimuli by relying on their chromatic or achromatic cues, or both. Antennae ablation was not only unnecessary for learning to occur but it even impaired visual conditioning due to a concomitant reduction of responsiveness to the electric shock. Both behavioral protocols, appetitive and aversive, open new doors for accessing the neural correlates of visual and/or bimodal learning and memory in honeybees. We also provided a comprehensive neuroanatomical description of unstudied visual circuits in the central bee brain. More specifically, we characterized the organization and neural architecture of the anterior optic tubercle (AOTu) and revealed a segregation of dorso-ventral visual information into this structure. Having established a novel protocol for performing optophysiological recordings of visual-circuit activity in the honeybee brain, we studied the responses of AOTu interneurons during visual stimulation of the compound eye. We showed that light stimuli presented in different parts of the visual field induced distinct patterns of activation in these interneurons, consistent with the dorso-ventral segregation revealed by our neuroanatomical data. Stimulation of AOTu interneurons with monochromatic lights and with chromatic mixtures induced distinct signal intensities, time-course dynamics and activity patterns, thus revealing intricate chromatic processing properties in this visual neuropil. Our studies provide therefore an innovative, multilevel analysis of visual processing in honeybees, spanning from behavioral studies on elemental and non-elemental visual learning to neurobiological studies on visual processing and coding in the honeybee central brain. Taken together our studies open new doors to investigate for the first time experience-dependent changes of neural activity in the bee brain related to visual and/or bimodal learning, a goal that has remained elusive until now

Повний текст джерелаA word is better identified when displayed in the right visual field (RVF) than in the left. The RVF superiority might be explained by the role of the left hemisphere in reading and by reading direction in left-to-right scripts. However the comparison between left-to-right and right-to-left scripts do not provide systemactic and clear differences. The primary goal of this dissertation was to determine the effects of reading direction on the RVF superiority in reading, and assess whether the influence of "environmental" writing could alter the attentional strategies of the readers. French and Hebrew words were displayed to bilingual participants but whose native language was French or Hebrew, living in France or in Israel. Results showed a larger RVF superiority in French than in Hebrew for all groups except among the Israeli group living in Israel. So there would have an effect of language, and environmental writing on the RVF superiority. With further experiments, we were also able to evaluate the effect of experimental context (confrontation of the two languages in the same block of trials) and linguistic familiarity (words vs pseudowords)
