Chris Eliasmith – How to Build a Brain

Via Futuristic news

He’s the creator of “Spaun” the world’s largest brain simulation. Can he really make headway into mimicking the human brain?

Chris Eliasmith has cognitive flexibility on the brain. How do people manage to walk, chew gum and listen to music all at the same time? What is our brain doing as it switches between these tasks and how do we use the same components in head to do all those different things? These are questions that Chris and his team’s Semantic Pointer Architecture Unified Network (Spaun) are determined to answer. Spaun is currently the world’s largest functional brain simulation, and is unique because it’s the first model that can actually emulate behaviours while also modeling the physiology that underlies them.

 

This groundbreaking work was published in Science, and has been featured by CNN, BBC, Der Spiegel, Popular Science, The Economist and CBC.He is co-author of Neural Engineering , which describes a framework for building biologically realistic neural models and his new book, How to Build a Brain applies those methods to large-scale cognitive brain models.

Chris holds a Canada Research Chair in Theoretical Neuroscience at the University of Waterloo. He is also Director of Waterloo’s Centre for Theoretical Neuroscience, and is jointly appointed in the Philosophy, Systems Design Engineering departments, as well as being cross-appointed to Computer Science.

MemoryMirror: First Body-Controlled Smart Mirror

The Intel® Core™ i7-based MemoryMirror takes the clothes shopping experience to a whole different level, allowing shoppers to try on multiple outfits, then virtually view and compare previous choices on the mirror itself using intuitive hand gestures. Users control all their data and can remain anonymous to the retailer if they so choose. The Memory Mirror uses Intel integrated graphics technology to create avatars of the shopper wearing various clothing that can be shared with friends to solicit feedback or viewed instantly to make an immediate in-store purchase. Shoppers can also save their looks in mobile app should they decide to purchase at a later time online.

Effects of mindfulness-based stress reduction on distressed (type D) personality traits

Effects of mindfulness-based stress reduction on distressed (type D) personality traits: a randomized controlled trial.

J Behav Med. 2013 Aug;36(4):361-70

 Authors: Nyklíček I, van Beugen S, Denollet J

Abstract. Distressed ('Type D') personality, the combination of negative affectivity (NA) and social inhibition (SI), has been associated with adverse health outcomes. The purpose of this study was to examine if an 8-week mindfulness-based stress reduction (MBSR) program could reduce Type D personality characteristics. Distressed individuals from the Dutch general population (N = 146; mean age = 46.07; 69 % female) participated in a randomized trial comparing the mindfulness intervention with waitlist control. Although change in Type D caseness did not differ between groups, the intervention group showed stronger reductions for both NA (p < .001) and SI (p < .05) dimensions, even when change in state negative affect was statistically controlled. These effects were mediated by change in self-reported mindfulness. In conclusion, MBSR may reduce characteristics of the distressed personality type, likely through the mechanism of increased mindfulness.

Mobile biofeedback of heart rate variability in patients with diabetic polyneuropathy: a preliminary study

Mobile biofeedback of heart rate variability in patients with diabetic polyneuropathy: a preliminary study.

Clin Physiol Funct Imaging. 2014 Jan 20;

Authors: Druschky K, Druschky A

Abstract. Biofeedback of heart rate variability (HRV) was applied to patients with diabetic polyneuropathy using a new mobile device allowing regularly scheduled self-measurements without the need of visits to a special autonomic laboratory. Prolonged generation of data over an eight-week period facilitated more precise investigation of cardiac autonomic function and assessment of positive and negative trends of HRV parameters over time. Statistical regression analyses revealed significant trends in 11 of 17 patients, while no significant differences were observed when comparing autonomic screening by short-term HRV and respiratory sinus arrhythmia at baseline and after the 8 weeks training period. Four patients showed positive trends of HRV parameters despite the expected progression of cardiac autonomic dysfunction over time. Patient compliance was above 50% in all but two patients. The results of this preliminary study indicate a good practicality of the handheld device and suggest a potential positive effect on cardiac autonomic neuropathy in patients with type 2 diabetes.

Transparent display @MIT

The innovative system is described in a paper published in the journal Nature Communications, co-authored by MIT professors Marin Soljačić and John Joannopoulos, graduate student Chia Wei Hsu, and four others.

Abstract of Nature Communications paper:

The ability to display graphics and texts on a transparent screen can enable many useful applications. Here we create a transparent display by projecting monochromatic images onto a transparent medium embedded with nanoparticles that selectively scatter light at the projected wavelength. We describe the optimal design of such nanoparticles, and experimentally demonstrate this concept with a blue-color transparent display made of silver nanoparticles in a polymer matrix. This approach has attractive features including simplicity, wide viewing angle, scalability to large sizes and low cost.

Wearable Pregnancy Ultrasound

Melody Shiue, an industrial design graduate from University of New South Wales, is proposing a wearable fetal ultrasound system to enhancing maternal-fetal bonding as a reassurance window. It is an e-textile based apparatus that uses 4D ultrasound. Latest stretchable display technology is also employed on the abdominal region, allowing other members of the family especially the father to connect with the foetus in its context. PreVue not only gives you the opportunity to interact and comprehend the physical growth of the baby, but also an early understanding of its personality as you see it yawning, rolling, smiling etc., bringing you closer till the day it finally rests into your arms.
