Primary sensorimotor signals, including both interoceptive and exteroceptive signals about the body, are integrated and re-represented in various levels of the neurocognitive hierarchy. This re-representation of information in higher cortical areas is assumed to allow conscious awareness and more flexible behavior. KatLab is interested in the precise neurobiological mechanisms by which bodily signals are integrated and re-mapped in the brain to ultimately form our coherent, conscious sense of embodiment. To understand the nature of the later we use several experimental ‘tricks’ from cognitive neuroscience to systematically manipulate sensorimotor signals, promote their integration, or generate conflicts and illusions, and hence study their role in body awareness in healthy individuals, as well as in prototypical, neuropsychological and neuropsychiatric disorders of body unawareness, such as anosognosia for hemiplegia.
Our body awareness is not something that depends solely (or solipsistically) on mental or brain processes that belong to the singular individual. Instead the self is socially or intersubjectively constituted. The notion of a socially constituted self has had many different voices in philosophy and more recently neuroscience. To this date debates unfold about the precise nature of intersubjectivity in relation to the architecture of the mind. In KatLab we attempt to address this topic by conducting unprecedented neuroscientific studies that focus on how the physical presence of others, as well as our interactions and relationship with them modulate our (inter)subjective experience of our body. We are particularly interested in how hierarchical re-mappings of interoceptive signals are modulated by social contextual factors and integrated with other sensorimotor information to form multimodal representations of the body.
