Lecture: Modeling the Body in the Mind
Speaker: Martin Butz (University of Tübingen)
How does the brain represent our own body? Multiple theories and even multiple terminologies are being discussed, refined, and questioned in the available literature. In this talk, I will discuss some of these aspects and attempt to shed some light on some basic, inevitably necessary neurocomputational principles that the brain employs for representing its own body. In doing so, I introduce a highly modularized, modal, neurocognitive body model. This body model simulates the continuous maintenance of an internal bodily representation, processing and integrating sensory information over time within and across modalities and modules. It is also possible to learn this model from scratch, simply by experiencing sensory and motor information about the own body. Moreover, I present recent results from a rubber hand illusion experiment conducted in our lab, which provides further support for the validity of the model. In closing, I present some recent thoughts and first results on developing neurocognitive models that are able to derive the perspective of another person solely based on the learned body model.
