Neuroscientists plant false memories in the brain

he phenomenon of false memory has been well-documented: In many court cases, defendants have been found guilty based on testimony from witnesses and victims who were sure of their recollections, but DNA evidence later overturned the conviction.

In a step toward understanding how these faulty memories arise, MIT neuroscientists have shown that they can plant false memories in the brains of mice. They also found that many of the neurological traces of these memories are identical in nature to those of authentic memories.

Chips that mimic the brain

Novel microchips imitate the brain’s information processing in real time. Neuroinformatics researchers from the University of Zurich and ETH Zurich together with colleagues from the EU and US demonstrate how complex cognitive abilities can be incorporated into electronic systems made with so-called neuromorphic chips: They show how to assemble and configure these electronic systems to function in a way similar to an actual brain.

A fatigue detection device for drivers based on eye tracking

An EPFL student, Peugeot Citroën, has developed a video analysis algorithm able to estimate the level of a driver’s fatigue based on the degree of eyelid closure and has built a prototype to test it in real driving conditions.

The future of gaming - using neurophysiological signals

Gaming as a hobby evokes images of lethargic teenagers huddled over their controllers, submerged in their couch surrounded by candy bar wrappers. This image should soon hit the reset button since a more exciting version of gaming is coming. It's called neurogaming, and it's riding on the heels of some exponential technologies that are converging on each other

Dust sized brain implants

In a potential neuroscience breakthrough, University of California Berkeley scientists have proposed a system that allows for thousands of ultra-tiny “neural dust” chips to be inserted into the brain to monitor neural signals at high resolution and communicate data highly efficiently via ultrasound.

The neural dust design promises to overcome a serious limitation of current invasive brain-machine interfaces (BMI): the lack of an implantable neural interface system that remains viable for
a lifetime. Current BMI systems are also limited to several hundred implantable recording sites, they generate tissue responses around the implanted electrodes  that degrade recording performance over time, and are limited to months to a few years.

Seeing How Your Brain Works in Real-time Helps to Improve It

In an experiment involving twenty volunteers with contamination anxiety, researchers from Yale University tested whether real-time neurofeedback can induce lasting changes in brain activity. Contamination anxiety is related to hyperactivity in the orbitofrontal cortex (OFC), a region of the brain thought to be involved in mood control and decision making. Showing the volunteers the activity in their OFC in a line-graph helped them to control their brain patterns. After eight sessions spread out over several days the volunteers reported a greater control over their anxiety and scans of their brain showed a corresponding decrease in connectivity in the regions associated with emotions.
