I've been busy lately working on a grant proposal so I have not had a chance to continue my comments on the recently published Mirror Neuron Forum. There hasn't been any involvement in that discussion by the forum participants anyway (unfortunately) so my motivation to work on it has dropped off a bit. I'll get back to that soon.
Right now I'm just curious if anyone has noticed that the mirror system has extended its reach into sensory systems. A recent review by Keysers, Kaas, and Gazzola (2010), for example, discusses the role of somatosensory cortex in social perception via simulating the experience of others. I haven't looked at this literature carefully, but on first glance it strikes me as rather odd to claim, as a novel idea inspired by mirror neurons, that sensory systems in the brain might be involved in sensing what is happening in the environment. What will the next claim be, that the visual system is important for object identification via simulation of object features? Radical! I must be missing something.
