Supramodal processing optimizes visual perceptual learning and plasticity - Multisensory interactions are ubiquitous in cortex and it has been suggested that sensory cortices may be supramodal capable of functional selectivity irrespective of the sensory modality of inputs (Pascual-Leone and Hamilton, 2001; Ricciardi and Pietrini, 2011; Voss and Zatorre, 2012; Renier et al., 2013). Here, we asked whether learning to discriminate visual coherence could benefit from supramodal processing. To this end, three groups of participants were briefly trained to discriminate which of a red or green intermixed population of random-dot-kinematograms (RDKs) was most coherent in a visual display while being recorded with magnetoencephalography (MEG). During training, participants heard no sound (V), congruent acoustic textures (AV) or auditory noise (AVn); importantly, congruent acoustic textures shared the temporal statistics – coherence – of visual RDKs. After training, the AV group significantly outperformed participants trained in V and AVn although they were not aware of their pr

– Enrico Fucci , Regulation of perceptual learning by mindfulness meditation : experiential and neurophysiological evidence - De part sa mise en pratique considérable dans des conditions cliniques, l’étude neuroscientifique de la méditation de pleine conscience a vu un développement rapide ces deux dernières décennies. Malgré des preuves de modifications de l’activité et de la structure du cerveau, les mécanismes neuronaux et cognitifs sous tendant les pratiques méditatives sont encore peu connus. Dans le présent travail nous avons testé l’hypothèse que la méditation de pleine conscience implique un changement dans la cognition de l’expérience vécue, impactant de ce fait la formation des habitudes mentales. Pour cela nous avons étudié la relation entre la phénoménologie de différents styles de méditation, chez des pratiquants experts et novices, et des marqueurs neurophysiologiques de l’apprentissage perceptuel ( négativité de discordance auditive) et de l’attention dans des conditions neutres et é avons trouvé qu’un style de méditation non-duel augmente la vigilance sens

Regulation of perceptual learning by mindfulness meditation : experiential and neurophysiological evidence - Due to its widespread implementation in clinical settings, the neuroscientific study of mindfulness meditation has seen a rapid growth in the last two decades. Despite the evidence of changes in brain activity and structures, the neurocognitive mechanisms underlying meditation practices are largely unknown. In this work, we investigated the hypothesis that mindfulness meditation entails a cognitive stance towards experience which impacts the formation of mental habits. With this aim, we studied the relationship between the phenomenology of different styles of mindfulness meditation, in expert and novice practitioners, and neurophysiological markers of perceptual learning ( auditory mismatch negativity) and attention in neutral and emotional settings. We found that a nondual style of mindfulness meditation increased sensory monitoring and reduced perceptual learning compared to a focused attention practice. Additionally, we demonstrated that auditory perceptual learning is not affected by unpredictable thr

Improving visual function through concomitant use of perceptual learning and brain stimulation : the case of macular degeneration - Macular degeneration (MD) is a common visual disorder in the aging population characterized by a loss of central vision, reduced visual acuity contrast sensitivity, and increased crowding. This impairment strongly affects the quality of life and personal autonomy. There is currently no cure for AMD, available treatment options are only able to slow down the disease, and even palliative treatments are rare. After the emergence of the central scotoma, patients with MD develop one or more eccentric fixation areas - preferred retinal loci (PRLs) - that are used for fixation, reading, tracking, and other visual tasks that require finer ocular abilities. The final goal of the project was to investigate and to improve the residual visual abilities in the PRL. Four studies were conducted in total. Study 1 was conducted in MD patients to investigate whether after the emergence of the scotoma, the PRL acquire enhanced abilities in the processing of the visual information through spontaneous or use-dependent adaptive pl

Tactile recognition of visual stimuli: Specificity versus generalization of perceptual learning - Sensory substitution devices aim at assisting a deficient sensory modality by means of another sensory modality. For instance, to perceive with visual-to-tactile devices, users learn to recognize visual stimuli through their tactile conversion. A crucial characteristic of learning lies in the ability to generalize, that is, the ability to extend the acquired perceptual abilities to both new stimuli and new perceptual conditions. The study reported here investigated the perceptual learning of tactile alphanumerical stimuli. The learning protocol consisted in alternating a repeated list of symbols with lists of new symbols. A first experiment revealed that, when each list consisted of 4 stimuli, recognition performance improved over time only for the repeated list. This result suggests that learning a small set of stimuli involves stimulus-specific learning strategies, preventing generalization. A second experiment revealed that increasing to six the set of learned stimuli results in higher generalization abili

Perceptual Learning and Abstraction in Machine Learning : an application to autonomous robotics - This paper deals with the possible benefits of Perceptual Learning in Artificial Intelligence. On the one hand, Perceptual Learning is more and more studied in neurobiology and is now considered as an essential part of any living system. In fact, Perceptual Learning and Cognitive Learning are both necessary for learning and often depends on each other. On the other hand, many works in Machine Learning are concerned with "Abstraction" in order to reduce the amount of complexity related to some learning tasks. In the Abstraction framework, Perceptual Learning can be seen as a specific process that learns how to transform the data before the traditional learning task itself takes place. In this paper, we argue that biologically-inspired Perceptual Learning mechanisms could be used to build efficient low-level Abstraction operators that deal with real world data. To illustrate this, we present an application where perceptual learning inspired meta-operators are used to perform an abstraction on an autonomous robo
