New Technique Allows Scientists to Read Minds at Nearly the Speed of Thought

Posted by in categories: biotech/medical, computing, neuroscience

An experiment by University of Washington researchers is setting the stage for advances in mind reading technology. Using brain implants and sophisticated software, researchers can now predict what their subjects are seeing with startling speed and accuracy.

The ability to view a two-dimensional image on a page or computer screen, and then transform that image into something our minds can immediately recognize, is a neurological process that remains mysterious to scientists. To learn more about how our brains perform this task—and to see if computers can collect and predict what a person is seeing in real time—a research team led by University of Washington neuroscientist Rajesh Rao and neurosurgeon Jeff Ojermann demonstrated that it’s possible to decode human brain signals at nearly the speed of perception. The details of their work can be found in a new paper in PLOS Computational Biology.

The team sought the assistance of seven patients undergoing treatment for epilepsy. Medications weren’t helping alleviate their seizures, so these patients were given temporary brain implants, and electrodes were used to pinpoint the focal points of their seizures. The UW researchers saw this as an opportunity to perform their experiment. “They were going to get the electrodes no matter what,” noted Ojermann in a UW NewsBeat article. “We were just giving them additional tasks to do during their hospital stay while they are otherwise just waiting around.”

Graphene shown to safely interact with neurons in the brain

Posted by in categories: biotech/medical, materials, neuroscience

Researchers have successfully demonstrated how it is possible to interface graphene — a two-dimensional form of carbon — with neurons, or nerve cells, while maintaining the integrity of these vital cells. The work may be used to build graphene-based electrodes that can safely be implanted in the brain, offering promise for the restoration of sensory functions for amputee or paralysed patients, or for individuals with motor disorders such as epilepsy or Parkinson’s disease.

The Technological Singularity: A Definition

Posted by in categories: neuroscience, singularity

(draft)

We’ve just posted a proposed definition of the notion of a technological singularity in our blog. Please comment freely.

Synopsis: Careful expositions of a technological singularity anticipated by the mid-21st century can be uniquely described using three common characteristics: superintelligence, acceleration, and discontinuity.

AI Benchmark Will ask Computers to Make Sense of the World

Posted by in categories: computing, neuroscience, robotics/AI

At this rate of making machines to behave and interact like humans; we may end up with a world with some really messed up robots.


A new database will gauge progress in artificial intelligence, as computers try to grasp what’s going on in scenes shown in photographs.

Phospholipid signaling in cancer, neurodegeneration and cardiovascular disease

Posted by in categories: biotech/medical, employment, neuroscience

Now, this is intriguing — pathways are a critical part of our system that monitors and manages how our bodies respond and interact to changes in our bodies. This recent SRC report focuses on the researchers efforts in monitoring pathways and how defects in pathways contribute to the biology and pathophysiology of cancer.


Bethesda, MD — This SRC focuses on new developments in the biology of lipid signaling with an emphasis on cancer, neuronal and cardiovascular diseases. The emphasis will be on molecular, cellular, structure/function and enzymatic mechanisms of physiological signaling pathways and how defects in these pathways contribute to the biology and pathophysiology of cancer, neurodegeneration and cardiovascular disease. The focus will be on how diacylglycerol, phosphatidic acid, lysophospholipids, sphingolipids and phosphoinositide lipids modulate specific pathways and processes in the contexts of physiological growth-regulatory signals, intracellular and extracellular vesicular trafficking, regulation of cell polarization, migration, motility and invasion, autophagy and epithelial extrusion, and as nuclear regulators of mRNA processing and gene expression. These sessions will include discussions on how signaling becomes dysfunctional in diseases. There will be presentations on new translational approaches and therapeutic targets. There will be significant representation from the pharmaceutical and biotechnology industry in order to facilitate networking between industry and academia. The topic areas have been chosen to maximize discussion of provocative and important developments.

We particularly wish to encourage the participation of new and junior researchers in the field and are securing additional support to provide PhD/postdoctoral fellow travel awards. Organizers have kept multiple short session speaking slots open. These will be selected from novel advances during 2015–2016 and from submitted abstracts. There will be multiple opportunities for new investigators and postdoctoral fellows to present and discuss their work including at poster sessions, short talks and short 5–10 minute oral ‘research snapshots’ to highlight their submitted abstracts. There will be multiple poster sessions during the conference. Time will also be allocated to at least two “meet the expert sessions” wherein established research leaders will dedicate time to interact with trainees and new investigators, specifically to give advice concerning the science and possible prospects for postdoctoral training, research funding, publishing or employment tracks.

Musician receives brain surgery while playing guitar

Posted by in categories: biotech/medical, neuroscience

Unbelievable


A patient playing guitar looks odd in a surgery but actually helps doctors detect his brain signals.

A 57-year-old guitar musician received a brain operation in Shenzhen on Jan 25 as he played his guitar through the whole session.

The patient suffered a rare neurological disease called musician’s dystonia.

Neural network based on polymeric memristors can potentially be used to build fundamentally new computers

Posted by in categories: computing, neuroscience, robotics/AI

Interesting approach.


A group of scientists has created a neural network based on polymeric memristors — devices that can potentially be used to build fundamentally new computers. These developments will primarily help in creating technologies for machine vision, hearing, and other machine sensory systems, and also for intelligent control systems in various fields of applications, including autonomous robots.

New algorithm points the way towards regrowing limbs and organs

Posted by in categories: biotech/medical, computing, information science, neuroscience

An international team of researchers has developed a new algorithm that could one day help scientists reprogram cells to plug any kind of gap in the human body. The computer code model, called Mogrify, is designed to make the process of creating pluripotent stem cells much quicker and more straightforward than ever before.

A pluripotent stem cell is one that has the potential to become any type of specialised cell in the body: eye tissue, or a neural cell, or cells to build a heart. In theory, that would open up the potential for doctors to regrow limbs, make organs to order, and patch up the human body in all kinds of ways that aren’t currently possible.

It was Japanese researcher Shinya Yamanaka who first reprogrammed cells in this way back in 2007 — it later earned him a Nobel Prize — but Yamanaka’s work involved a lot of labourious trial and error, and the process he followed is not an easy one to reproduce. Mogrify aims to compute the required set of factors to change cells instead, and it’s passed its early tests with flying colours.
