Models of Consciousness and Clinical Implications
Phenomenal consciousness appears to be continuous and unified, while experimental studies and theoretical models suggest that the brain involves discrete transitions and distributed processing. For the appearant continuity and unity temporal and spatial coordination needs to take place in the brain. Impairment of this pivotal coordination might underlie a set of neuronal and psychopathological conditions. At subjective level this impairment seems to result in existential fears or clinical symptoms, as there occurs a loss of the feeling of agency and identity. This is often followed by unwholesome dysfunctional coping reactions in order to avoid this awareness. On the other hand, several recent studies suggest that mindfulness, i.e. non-judgemental attention to present moment experience (meta-awareness), has a salutary influence on such psychopathological effects. Mindfulness seems to be lowering negative reactions to uncoordinated brain mechanisms. How mindfulness achieves this is not understood. The project aims at understanding more of the mentioned mechanisms.
