# brain behav: a hypothesis of 'loss of self' when they have to assume a 'fictional perspective'

In a functional MRI (Magnetic Resonance Imaging) study, AA << sought to identify brain regions preferentially activated when actors adopt a Fic1P (fictional first-person) perspective during dramatic role playing. >>

<< Compared to responding as oneself, responding in character produced global reductions in brain activity and, particularly, deactivations in the cortical midline network of the frontal lobe, including the dorsomedial and ventromedial prefrontal cortices. Thus, portraying a character through acting seems to be a deactivation-driven process, perhaps representing a 'loss of self'. >>

# phys: a base-level fuzziness; black holes and strange metals go to extremes in some common way

<< black holes and strange metals go to extremes in some common way (..)  electrons inside a variety of ceramic crystals called "cuprates" seem to dissipate energy as quickly as possible, apparently bumping up against a fundamental quantum speed limit. >>

# ai.bot: adaptive robotics, the beginning

<< The goal of Zhao's lab is to create small, lightweight robots that can reconfigure themselves in response to a need. "In general, if you have a robot, its mechanical structure is fixed," says Zhao [Jianguo Zhao], an assistant professor in the Department of Mechanical Engineering. "If we can change the mechanical structure on the fly, without redesigning the robot, this is pretty useful, especially if the robot is very small … I don't think many people are trying to do that." >>
