Event Related Optical Signal

Event Related Optical Signal or EROS is a relatively young, non-invasive neuroprosthetic input method which used channelled infra-red light, typically through the medium of an optic fibre bundle, to pierce the skin and skull, peering into the brain.

EROS takes advantage of the scattering properties of neurons within the brain, to detect which sections are firing at any given time. It has an impressive degree of accuracy, almost unheard of in non-invasives, able to deal with volumetric spaces of a cubic millimetre of brain tissue at a time. However, due to the absorbent properties of brain tissue, currently EROS can only scan a few centimetres deep into the brain. Anything else is hidden, masked by the neurons in front.

Automated Calibration Method Developed for Optical Microscopes - and HMDs

An automated calibration method, designed for optical microscopes, may find a home in head mounted display units and heads-up augmented reality systems.

Organized Roleplaying Events
Organising even a handful of players into a cohesive, functional group for a roleplayed event is a nightmare for any persistent world. However, if you are not running a gameworld, or alternate life world, but desire a one-shot roleplay event with whoever is in world at the time, you can. Here is how to set it up.

A Survey of Health-Related Activities on Second Life
The Journal of Medical Internet Research has published a fairly comprehensive list of the health-related initiatives in just one single social VR platform. The scope is quite impressive.

Optogenetics and Neuroprosthetics Combine
Optogenetics as a field of study, is only a few years old but already a means has been found to make use of it in living brains. Light-detecting proteins combined with gene therapy and an optical neuroprosthetic with a BrainGate style 3D array allow true two-way communication between the brain and a computer system.

White House Deputy CTO Holds Dual Reality Event
Details of the first official US Government conference to address avatars in a virtual reality on an equal footing to physically present guests.

Large Image Display: Chrysalis: Optical Door Locks
This still from Chrysalis shows a very different method of locking and unlocking your front door than we are used to. There is no key and no key hole. Instead, what there is is a retinal scanner embedded in the door level with the average head. Peer in and if it recognises you, it unlocks. If not, there is nothing to pick.

Sensory Malfunction: Taste
A look at what taste is, as a sense, and the possible malfunctions - what can go wrong with the taste reaching the brain, attempting to explain in signal propogation terms. Intended to assist the creation of taste-based sensory systems for VR.

Understanding Grows on Roots of Memory
A digital signal processing technique long used by statisticians to analyse data, is being applied to the brain in a novel endeavour by researchers from Rice University, to understand the roots of memory and learning, along with diseases such as Alzheimer's and Parkinson's and stroke.
