Humans Ignore Motion and Stereo Cues in Favor of a Fictional Stable World
Humans Ignore Motion and Stereo Cues in Favor of a Fictional Stable World.
Curr Biol. 2006 Feb 21;16(4):428-432
Authors: Glennerster A, Tcheang L, Gilson SJ, Fitzgibbon AW, Parker AJ
As we move through the world, our eyes acquire a sequence of images. The information from this sequence is sufficient to determine the structure of a three-dimensional scene, up to a scale factor determined by the distance that the eyes have moved . Previous evidence shows that the human visual system accounts for the distance the observer has walked and the separation of the eyes when judging the scale, shape, and distance of objects. However, in an immersive virtual-reality environment, observers failed to notice when a scene expanded or contracted, despite having consistent information about scale from both distance walked and binocular vision. This failure led to large errors in judging the size of objects. The pattern of errors cannot be explained by assuming a visual reconstruction of the scene with an incorrect estimate of interocular separation or distance walked. Instead, it is consistent with a Bayesian model of cue integration in which the efficacy of motion and disparity cues is greater at near viewing distances. Our results imply that observers are more willing to adjust their estimate of interocular separation or distance walked than to accept that the scene has changed in size.

Meditation may increase the thickness of the cortex
Science and Consciousness Review has interviewed brain researcher Sara Lazar on how meditation affects the brain. Lazar is the author of a recent study, in which magnetic resonance imaging was used to assess cortical thickness in 20 participants with extensive Insight meditation, a technique that involves focusing attention on internal experiences. Findings showed that brain regions associated with attention, interoception and sensory processing were thicker in meditation participants than matched controls, including the prefrontal cortex and right anterior insula. According to Lazar and her colleagues, these results provide preliminary evidence for experience-dependent cortical plasticity associated with meditation practice.

STS Italia is a research network which connects Italian scholars and academics interested in studying science and technology at both theoretical and empirical level.
The approaches and research perspectives pursued in the network consider relationships among science technology and society as a thick texture involving heterogenous actors, and reject any deterministic prejudice about the role of technoscience in society.
Research interests characterizing STS Italia concern theoretical and empirical analysis of science and technology in different contexts (from ‘laboratory studies’ to socio-technical networks; ftrom public perception of biotechnologies to domestication of technologies in everyday life).
STS Italia is inspired by the STS approach (Science and Technology Studies), which constitutes an inter- and trans-disciplinary field well known and institutionalized in Europe and the U.S.
The aim of STS Italia is to promote exchange, discussion and to strengthen the debate on science technology and society inside and outside Italian Universities.
The conference aims to attract a wide audience and broad participation, bringing together researchers engaged in investigating science and technology issues and willing to share their experience during plenary sessions and parallel workshops of the event. Younger researchers and Ph.D. students from University and other research centres are particularly welcome.
Provisional conference program
Plenary session 1
“STS: an international perspective. The state of the art in Science and Technology Studies”
Plenary session 2
“Technoscientific innovation and society: the Italian context”

Exploring spike transfer through the thalamus using hybrid artificial-biological neuronal networks
Exploring spike transfer through the thalamus using hybrid artificial-biological neuronal networks.
J Physiol Paris. 2004 Jul-Nov;98(4-6):540-58
Authors: Debay D, Wolfart J, Le Franc Y, Le Masson G, Bal T
We use dynamic clamp to construct "hybrid" thalamic circuits by connecting a biological neuron in situ to silicon- or software-generated "neurons" through artificial synapses. The purpose is to explore cellular sensory gating mechanisms that regulate the transfer efficiency of signals during different sleep-wake states. Hybrid technology is applied in vitro to different paradigms such as: (1) simulating interactions between biological thalamocortical neurons, artificial reticular thalamic inhibitory interneurons and a simulated sensory input, (2) grafting an artificial sensory input to a wholly biological thalamic network that generates spontaneous sleep-like oscillations, (3) injecting in thalamocortical neurons a background synaptic bombardment mimicking the activity of corticothalamic inputs. We show that the graded control of the strength of intrathalamic inhibition, combined with the membrane polarization and the fluctuating synaptic noise in thalamocortical neurons, is able to govern functional shifts between different input/output transmission states of the thalamic gate.

SKeeper
Tadiran LifeCare, an Israeli company, has presented a compact wearable mobile communication and safety device (SKeeper™) for the elderly. The device
enables users to carry on with their daily routines without compromising safety and well being, by enabling them to stay in touch with relatives and caregivers in case of need. With SKeeper™ elderly people get immediate assistance by simply pressing a single button on the device, and parents can rest assured that their children can easily contact them should they be lost or need assistance
...
Using its embedded Siemens MC55 wireless module and built-in speakerphone, SKeeper™ can activate cellular voice calls to pre-defined numbers (e.g. a relative or a health professional) or receive calls from anyone. When a call is made to a monitoring center, a pre-defined SMS message can be sent automatically to a relative. Incoming calls can be screened and/or answered automatically. Most of the product features, such as speed dialing numbers, auto-answering, predefined text messages, etc. are remotely programmable by the monitoring center, or by the users or their authorized relatives via a Web based interface.

Effect of age and timing of augmented feedback on learning muscle relaxation
Effects of age and timing of augmented feedback on learning muscle relaxation while performing a gross motor task
Am J Phys Med Rehabil. 2006 Feb;85(2):148-55; quiz 156-8
Authors: van Dijk H, Hermens HJ
OBJECTIVE: To examine the combined effect of age and timing of augmented feedback on learning muscle relaxation. Performing a gross motor task, subjects had to lower their trapezius muscle activity using the electromyographic signal as visual myofeedback. DESIGN: Healthy subjects (16 young adults: 20-35 yrs; and 16 older adults: 55-70 yrs) were randomly assigned to one of two timing conditions of myofeedback: concurrent (feedback was provided immediately during the trial) and terminal (feedback was provided delayed after the trial) condition. RESULTS: The results indicated that young adults had a higher level of motor performance (i.e., lower muscle activity) compared with older adults when myofeedback was provided. These effects persisted during short- (after 10 mins) and long-term retention (after 1 wk) when no myofeedback was provided. In contrast to young adults, older adults did not improve their performance throughout the experiment. There were no interactions of age with the timing conditions of myofeedback during acquisition and retention. CONCLUSIONS: Either timing condition of augmented feedback was equally helpful to young adults, whereas neither was helpful for older adults in learning muscle relaxation.

Therapy in IVR-Cave 'holodeck'
Via the Presence-Listserv
(the following excerpt is from the original article published in the Observer)
Inspired by Star Trek's holodeck, a virtual reality theatre will be built for treatment and therapy purposes at the Cleveland Hearing and Speech Center. The theatre is titled, "Immersive Virtual Reality Cave Simulator" (IVR-Cave).
Under the guidance of Stacy Willams, an assistant professor in communication services at Case, the construction on the theater will be complete by April 2006. Williams formulated the concept of the room with inspiration from Star Trek while she was working on her master's degree."I was intrigued by the whole holodeck concept, and at the time [when working on a masters degree], I was learning the importance of carry-over techniques, or generalizing what you learn in therapy to a natural environment," Williams said.
With this new simulator, therapists will get a chance to show patients real-life scenarios in a controlled environment, before they are out on their own in the real world...

Forearm implanted chip to create an human-Ipod network
Researchers at the Korea Advanced Institute of Science and Technology (KAIST) presented a chip that is implanted in a user’s forearm to function as an audio signal transmission wire that links to an iPod. Many of the presentations featured devices that conserved power, though this chip goes a step further, harnessing the human body’s natural conductive properties to create personal-area networks. It is not practical to wire together the numerous devices that people carry with them, and Bluetooth connections fall prey to interference, leading scientists to explore the application of the human body as a networking cable. The Korean scientists augmented an iPod nano with their wideband signaling chip. When a user kept his finger pressed to the device, it transmitted data at 2 Mbps, at a consumption rate lower than 10 microwatts. Researchers from the University of Utah also presented a chip that scans brainwave activity by wirelessly streaming data through monitors in the hopes of creating prosthetics that quadriplegics could operate with their brain waves, though both projects are still in the preliminary research stages.

These chips are not something that will be included in one of Apple Computer CEO Steve Jobs’ Macworld keynotes anytime soon.
