Current scientific interest My interest in the psychopathology of intention originated from a longstanding practice of research on the brain mechanisms of action. I had been working in the past on sensory-motor coordination, on hand movements, and more generally on the way actions are internally represented and encoded. In the 1990s, we had discovered some of the properties of action representations, by using a classical model, that of motor imagery. We had found that imagining an action activated mechanisms quite similar to those of real actions. The most striking aspect of this finding is that action imagination is related to an activation of those cortical and subcortical motor areas (including primary motor cortex), which participate in the command of executed action. Hence the hypothesis, which is still nowadays the subject of intensive scrutiny by cognitive neuroscientists, that representing an action consists in simulating the mechanisms, like programming and generating the motor commands, that would be used to actually execute that action. This hypothesis has deep implications in several domains of motor neuroscience. Action simulation could represent the basis for learning skills: for example, mental rehearsal, learning by observing others’ actions or motor rehabilitation techniques, would be direct implementations of this ability to internally represent or simulate an action. This work on action representations also opens new avenues on the way one identifies and recognizes one’s own actions. Normal subjects seem to achieve this task of self-recognition by internally monitoring the efferent signals generated when an action is intended, represented and eventually executed. These efferent signals are matched with the afferent signals (e.g., visual, kinesthetic) that result from the execution
  • itself, and the degree of correlation between these internal and external signals determines their origin. We showed that this correlation is achieved in the inferior parietal lobule, a cortical area where the efferent motor information and the afferent visual and somatosensory information merge together. Indeed, focal parietal lesions lead to striking deficits in self-recognition: patients with such lesions may fail to recognize their own actions and their own body parts, which they may even attribute to someone else. One direct consequence of action recognition is self-recognition. By identifying myself as the agents of my actions, I distinguish myself from other selves. We know from clinical psychiatry that certain psychotic states are characterized by difficulties in attributing actions to their proper agent. Schizophrenic patients, for example, may experience verbal hallucinations by attributing their own internal speech to someone else. We found that such patients show abnormal activity in their inferior parietal lobule while attempting to disentangle their own actions from those of other agents. This finding demonstrates the validity of a trait approach of complex entities like schizophrenia. Here we have an indication that a defective monitoring of one’s actions may lead to pathological symptoms like hallucinations, delusions or depersonalization.
