Paralyzed Patients Move a Robotic Arm With Their Own Thoughts

With the BrainGate interface, Cathy Hutchinson, who is paralyzed from the neck down, moved a robotic arm toward a coffee cup, grasped it and was able to take a drink. It was the first time in 15 years that she was able to drink her coffee on her own. […]

Nicholas Carr Foresees Brains Optimized for Browsing

"In simple terms, our brains seek efficiency — they adapt, at a cellular level, to the way we use them, strengthening frequently used modes of thinking and weakening modes of thinking that we don’t exercise."

New method offers automated way to record electrical activity inside neurons in the living brain.

Gaining access to the inner workings of a neuron in the living brain offers a wealth of useful information: its patterns of electrical activity, its shape, even a profile of which genes are turned…

Brain Implants Help Paralyzed Monkeys Get a Grip

Spinal cord injuries cause paralysis because they sever crucial communication links between the brain and the muscles that move limbs. A new study with monkeys demonstrates a way to re-establish those connections. By implanting electrodes in a movement control center in the brain and wiring them up to electrodes attached to muscles in the arm, researchers restored movement to monkeys with a temporarily paralyzed hand. The work is the latest promising development in the burgeoning field of neuroprosthetics.

New Genes Linked to Brain Size, Intelligence

 In the world’s largest brain study to date, a team of more than 200 scientists from 100 institutions worldwide collaborated to map the human genes that boost or sabotage the brain’s resistance to a variety of mental illnesses and Alzheimer’s disease. Published April 15 in the advance online edition of Nature Genetics, the study also uncovers new genes that may explain individual differences in brain size and intelligence.

Could Military Mind Control Get Out of Hand?

recent article in U.S. News & World Report detailed advances in neuroscience that could possibly be used by the military: “tanks controlled from half a world away, memory erasures that could prevent PTSD, and ‘brain fingerprinting’ that could be used to extract secrets from enemies.”

Data mining opens the door to predictive neuroscience | KurzweilAI

Ecole Polytechnique Fédérale de Lausanne (EPFL) researchers havediscovered rules that relate the genes that a neuron switches on and off to the shape of that neuron, its electrical properties, and its location in the brain.

The discovery, using state-of-the-art computational tools, increases the likelihood that it will be possible to predict much of the fundamental structure and function of the brain without having to measure every aspect of it.

That in turn makes modeling the brain in silico — the goal of the proposedHuman Brain Project — a more realistic, less Herculean, prospect.

“It is the door that opens to a world of predictive biology,” says Prof. Henry Markram.

Human Attention to a Particular Portion of an Image Alters the Way the Brain Processes Visual Cortex Responses to That Image

Our ability to ignore some, but not other stimuli, allows us to focus our attention and improve our performance on a specific task. The ability to respond to visual stimuli during a visual task hinges on altered brain processing of responses within the visual cortex at the back of the brain, where visual information is first received from the eyes. How this occurs was recently demonstrated by an international team of researchers led by Justin Gardner at the RIKEN Brain Science Institute in Wako.

Once Considered Mainly ‘Brain Glue,’ Astrocytes’ Power Revealed

A type of cell plentiful in the brain, long considered mainly the stuff that holds the brain together and oft-overlooked by scientists more interested in flashier cells known as neurons, wields more power in the brain than has been realized, according to new research published March 29 in Science Signaling.

Study Shines Light On Brain Mechanism That Controls Reward Enjoyment

 What characterizes many people with depression, schizophrenia and some other mental illnesses is anhedonia: an inability to gain pleasure from normally pleasurable experiences……Exactly why this happens is unclear. But new research led by neuroscientists at the University of North Carolina at Chapel Hill School of Medicine may have literally shined a light on the answer, one that could lead to the discovery of new mental health therapies
