Henry Markram Talks Brain Simulation

Henry Markram Talks Brain Simulation

The preliminary work for simulating the human brain is already under way 3. Engineering Cognition Artificial intelligence is progressing rapidly, and its impact on our daily lives will only increase. Today, there are still many things humans can do that computers can’t. But will it always be that way? Should we worry about a future in(…)

The Human Brain Project Reboots: A Search Engine for the Brain Is in Sight

The massive €1 billion project has shifted focus from simulation to informatics Image: Dan Saelinger 2. The Mechanics of the Mind Photo: Dan Saelinger The human brain is smaller than you might expect: One of them, dripping with formaldehyde, fits in a single gloved hand of a lab supervisor here at the Jülich Research Center, in(…)

What Happens in Your Brain When You Learn a Song

What Happens in Your Brain When You Learn a Song

The human neocortex learns and recognizes new songs with amazing efficiency. See how it works The neocortex is the part of the human brain that processes the world around us. It controls language and motor function. It helps us recognize our friends’ faces or our favorite songs. And it’s where our brain stores all of the(…)

How to Digitize a Rat Brain

AI experts hunt for the secrets of intelligence in 1 cubic millimeter of brain tissue 2. The Mechanics of the Mind While AI designers are creating powerful machines that can beat humans at many complex cognitive endeavors, they’re still envious of the human brain’s facility with certain seemingly simple tasks: such as recognizing a face after(…)

We Could Build an Artificial Brain Right Now

We Could Build an Artificial Brain Right Now

Large-scale brainlike systems are possible with existing technology—if we’re willing to spend the money Photo: Dan Saelinger 3. Engineering Cognition Photo: Dan Saelinger Brain-inspired computing is having a moment. Artificial neural network algorithms like deep learning, which are very loosely based on the way the human brain operates, now allow digital computers to perform such extraordinary feats(…)

The Benefits of Building an Artificial Brain

Massive efforts to better understand the human brain will deliver on the original promise of computer science: machines that think like us Illustration: Chad Hagen 1. A Unique Machine Illustration: Chad Hagen In the mid-1940s, a few brilliant people drew up the basic blueprints of the computer age. They conceived a general-purpose machine based on a processing(…)

The Brain as Computer: Bad at Math, Good at Everything Else

Modeling computers after the brain could revolutionize robotics and big data Illustration: Chad Hagen 1. A Unique Machine Illustration: Chad Hagen Painful exercises in basic arithmetic are a vivid part of our elementary school memories. A multiplication like 3,752 × 6,901 carried out with just pencil and paper for assistance may well take up to a minute.(…)

New Buzz on Brain Stimulation for Depression

New Buzz on Brain Stimulation for Depression

Treatments that target specific neural circuits provide better results Illustration: iStockphoto Here are three things we know for sure about deep brain stimulation (DBS) as a treatment for severe depression: 1. When the pacemaker-like brain implants do help depressed people, those people get dramatically better. “I have patients who got their implants 10 years ago now,”(…)

From Macro to Micro: A Visual Guide to the Brain

Here’s how the brain’s 86 billion neurons do their work Illustration: James Provost In the human brain, higher-level information processing occurs in the neocortex, neural tissue that forms the outer layer of the cerebral cortex. In its intricate folds, brain cells work together to interpret sensory information and to form thoughts and plans. The neocortex is divided(…)
