“…Considering the construction of the inter-subjective mind, the PPC has been well-acknowledged for its contribution to agency (Schwabe & Blanke, 2007;Tsakiris, Prabhu, & Haggard, 2006), intention (Andersen & Buneo, 2002;Andersen & Cui, 2009) and motor simulation (Kosslyn et al, 2001;Kosslyn, Ganis, & Thompson, 2006). Blanke -among other researchers -proposes that the sense of agency is related to the level of anticipation across the sensorimotor signals.…”

Exploiting the gain-modulation mechanism in parieto-motor neurons: Application to visuomotor transformations and embodied simulation

The so-called self-other correspondence problem in imitation demands to find the transformation that maps the motor dynamics of one partner to our own. This requires a general purpose sensorimotor mechanism that transforms an external fixation-point (partner's shoulder) reference frame to one's own body-centered reference frame. We propose that the mechanism of gain-modulation observed in parietal neurons may generally serve these types of transformations by binding the sensory signals across the modalities with radial basis functions (tensor products) on the one hand and by permitting the learning of contextual reference frames on the other hand. In a shoulder-elbow robotic experiment, gain-field neurons (GF) intertwine the visuo-motor variables so that their amplitude depends on them all. In situations of modification of the body-centered reference frame, the error detected in the visuo-motor mapping can serve then to learn the transformation between the robot's current sensorimotor space and the new one. These situations occur for instance when we turn the head on its axis (visual transformation), when we use a tool (body modification), or when we interact with a partner (embodied simulation). Our results defend the idea that the biologically-inspired mechanism of gain modulation found in parietal neurons can serve as a basic structure for achieving nonlinear mapping in spatial tasks as well as in cooperative and social functions.

“…Stimulus-driven tasks of this sort have been successful in demonstrating relative increases in DMN activity for a variety of cognitive processes which together can be loosely characterized as intrinsically oriented and self related processes. These include, among others, selfrepresentation (Goldberg et al, 2006;Kelley et al, 2002;Tononi and Koch, 2008;Uddin et al, 2007), autobiographic and prospective memory Andrews-Hanna et al, 2010b;Bar, 2007), mentalizing or theory-of-mind (Buckner et al, 2008;Saxe and Kanwisher, 2003;Spreng et al, 2009) agency (Schwabe and Blanke, 2007) as well as volition (Goldberg et al, 2008).…”

Stimulus-free thoughts induce differential activation in the human default network

“…This integration is suspected to occur in the parietal cortex with a separated functioning for synchrony and asynchrony detection [17] but sharing the same circuits for representing self and other [47]. It follows that different perceptual experiences can produce other kinds of agency patterns, as in well-known developmental experiments (see [1], [3], and [51]); i.e., delays between vision and proprioceptive information or the mirror test.…”

“…The sense of agency corresponds to the prereflective experience or sense that I am the cause or author of a movement (e.g., an experience that I am in control of my action [1]- [3]). Babies, early in their first months, acquire rapidly this sense of self distinct from others that allows them to develop later on higher cognitive skills such as social interactions and imitation.…”

Abstract-Agency is the sense that I am the cause or author of a movement. Babies develop early this feeling by perceiving the contingency between afferent (sensor) and efferent (motor) information. A comparator model is hypothesized to be associated with many brain regions to monitor and simulate the concordance between self-produced actions and their consequences. In this paper, we propose that the biological mechanism of spike timing-dependent plasticity, that synchronizes the neural dynamics almost everywhere in the central nervous system, constitutes the perfect algorithm to detect contingency in sensorimotor networks. The coherence or the dissonance in the sensorimotor information flow imparts then the agency level. In a head-neck-eyes robot, we replicate three developmental experiments illustrating how particular perceptual experiences can modulate the overall level of agency inside the system; i.e., 1) by adding a delay between proprioceptive and visual feedback information, 2) by facing a mirror, and 3) a person. We show that the system learns to discriminate animated objects (self-image and other persons) from other type of stimuli. This suggests a basic stage representing the self in relation to others from low-level sensorimotor processes. We discuss then the relevance of our findings with neurobiological evidences and development psychological observations for developmental robots.
