Via Vaughan at MindHacks, comes this link to a preview of a documentary-in-progress on The Blue Brain, that epic attempt to create a conscious supercomputer.
I was fortunate enough to profile the Blue Brain in 2008:
In the basement of a university in Lausanne, Switzerland sit four black boxes,…
The image on the right is a supercomputer simulation of the microcircuitry found within a column from the neocortex of the rat brain.
The simulation is a tour de force of computational neuroscience: a single column is a highly complex structure, containing approximately 10,000 neurons and 30…
Henry Markram, the director of the Blue Brain project, recently delivered a talk at TED that's gotten lots of press coverage. (It was the lead story on the BBC for a few hours...) Not surprisingly, all the coverage focused on the same stunningly ambitious claim, which is Markram's assertion that an…
Here's a juicy one from the Aug 24 Science.
Labs in Switzerland and the UK have independently used visual tricks to induce "out-of-body" experiences in healthy lab volunteers. At the UK lab -- the ever-productive Wellcome Trust Centre for Neuroimaging in London -- they seem to have combined some…
If we depend on visual cues to locate ourselves within the body, where do blind people locate their sense of self? Are there more reports of a sense of dislocation, including out of body experiences, in the blind?
Proprioception involves more than just visual cues. For example, blind people can use sensory information from the hands and feet.
Thanks, Mo. I had read a BBC article about this experiment earlier today that implied our sense of location is mainly visual. If proprioception involves all sensory clues, this may be why so many people find VR a disorienting and irritating experience. It may take a holodeck to make it fun.
This requires stroking but doesn't precise where to stroke. Maybe if someplaces are stroked you can get-out-of-mind experiences.
The above article mistakenly described the experiences produced by the research teams as out-of-body experiences. The journal Science and Science News (AAAS) describe that this week's issue of Science, two teams of cognitive neuroscientists independently report methods for inducing elements of an out-of-body experience in healthy volunteers. The operating word is elements. The experiences reported by the volunteers have 3 elements of some out-of-body experiences but they were not in fact out-of-body experiences a distinct state of consciousness and neurophysiology from the normal waking state.
The OBE is characterized by a visceral feeling of being embodied in a more subtle body away from the physical body itself, often with exotic "energetic," "take-off" and "re-interiorization" sensations. In the virtual reality experiment volunteers did not feel they were no longer present in their body and did not report these other characteristics of the OBE (significantly more numerous than the 3 selected by the researchers).
In an OBE, the individual is not always looking back at the physical body at a few feet of distance (although this can occur in some cases). OBEs are not always a visual phenomena either, as there are OBEs without sight and blind people may have OBE's. The majority of OBEs also occur mainly when the eyes are closed and when the body is in a more vegetative state with brain wave patterns distinct from even lucid dreaming -- let alone the normal waking state of the volunteers.
