Cognitive neurosciences / neuropsychology /neuroeconomy
The Audition team is investigating the mechanisms of auditory perception, at the interface between low-level processing of acoustic features and high-level cognitive processes. We use a wide range of tools in order to address this research topic, from single unit recordings in behaving animals to advanced psychophysics and EEG in human subjects. Current projects in the lab revolve around three major threads:
The prefrontal cortex (PFC) is a major challenge in Neurosciences. This brain region controls behavior adaptation and highercognitive functions that are needed for complex social interaction, abstract thinking, reasoning, planning or creativity.
Language is a complex cognitive function, involving the processing of several interacting levels of linguistic structure (e.g., phonology, syntax, semantics). The aim of our research is to understand the (neuro-)psychological mechanisms underlying the processing of human language in adults and its rapid and efficient acquisition in infants and young children.
The Brain Dynamics group focuses on the chronoarchitecture of the Human brain supporting perception and cognition.Our work is committed to the view that perception and cognition rely on inferential brain processes which are fundamental to contemporary theories of cortical functions. Neural inferences are shaped by both hard and soft constraints e.g. cognitive architecture and plasticity, respectively.
The Aging in Vision and Action team is a new research group created in 2014 at the Institute of Vision, Paris. It aims at gaining a better understanding of the perceptive and cognitive disturbances occurring with natural visual ageing in humans. Natural ageing of the visual system induces a complex pattern of perceptual, cognitive, and executive disturbances. The natural progressive degradation of visual functions in the elderly is the core subject of the Aging in Vision and Action team.
Currently developping several research topics
1- Spike-based predictive coding:
The PICNIC lab is devoted to the study of cognitive functions with an exclusive or prevalent development in humans, namely language and conscious cognition. The study of brain-damaged patients occupies a central position in our methodological approach. For the study of both language and consciousness, and with both patients and healthy subjects, we resort to state-of-the-art behavioural methods and multimodal brain imaging (MRI, high-density surface EEG and intracerebral implanted electrodes).
Our team is composed of cognitive scientists working on the neurobiological and psychological foundations of consciousness. We are especially interested in how conscious and unconscious processes differ at both the psychological and neural level. We use various behavioral methods (e.g., priming, psychophysics) and brain imaging techniques (e.g., fMRI, EEG) to study how humans process things unconsciously (e.g., as in situations of subliminal perception, sleep or hypnosis) and compare it to situations of conscious processing.
The long-term objective of this project is to apply high field MRI eventually combined with other neuroscience approaches, to develop physical (e.g. electric neurostimulation) and/or chemical (e.g. pharmacological delivery) devices of neuromodulation that target neuronal sites and manipulate specific aspects of cognition, motor behavior or consciousness, leading ultimately to the development of treatments for patients with related diseases (e.g. disorders of consciousness, Parkinson's disease...).
