How the human brain processes the words we hear and constructs complex concepts is still somewhat of a mystery to the neuroscience community. Transcranial direct current stimulation (tDCS) can alter our language processing, allowing for faster comprehension of meaningful word combinations, according to new research from the department of Neurology the Perelman School of Medicine at the University of Pennsylvania. The work is published in the Journal of Neuroscience.

“Integrating conceptual knowledge is one of the neural functions fundamental to human intelligence,” said the study’s first author Amy Price, a neuroscience graduate student at Penn. “For example, when we read or listen to a sentence, we need to combine, or integrate, the meaning of the words to understand the full idea of the sentence. We perform this process effortlessly on a daily basis but it is quite a complex process and little is known about the brain regions that support this ability.”

Semantic memory is our stored knowledge about the world, such as the meaning of words and objects. “We sought to understand how and in what part of the brain semantic representations are integrated into more complex ideas” said senior author Roy Hamilton, MD, MS, an assistant professor in the departments of Neurology and Physical Medicine & Rehabilitation, and director of the Laboratory for Cognition and Neural Stimulation at Penn. Recent findings from functional MRI scans (fMRI) and magnetoencephalography (MEG) have suggested the angular gyrus, a region of the brain known to be involved in language, number processing and spatial cognition, memory retrieval and attention, as a potential hub for semantic memory integration, specifically the left angular gyrus.

The blood-brain barrier has stymied direct treatment of brain disorders. In a recently published study, a researcher reports finding a way to pass therapeutics through the barrier, using readily-available agents.

I see great potential for the TrueNorth chip as we migrate towards Quantum & Singularity. TrueNorth is an interim chip that assists researchers, engineers, etc. in their efforts to mimic the human brain’s nuero sensors and processing for robotics, BMI technology, etc.

The new IBM supercomputer chip mimics the human brain by using an architecture with 1 million neurons. Nevertheless, its true purpose remains in question for a project with massive public funding.

30.03.16 — Public Release of Platforms Will Help Advance Collaborative Research in Neuroscience, Medicine, and Computing

The Human Brain Project (HBP) is pleased to announce the release of initial versions of its six Information and Communications Technology (ICT) Platforms to users outside the Project. These Platforms are designed to help the scientific community to accelerate progress in neuroscience, medicine, and computing.

The Platforms released today consist of prototype hardware, software tools, databases and programming interfaces, which will be refined and expanded in a collaborative approach with users, and integrated within the framework of a European Research Infrastructure. The public release of the Platforms represents the end of the Ramp-Up Phase of the HBP and the beginning of the Operational Phase.

The TrueNorth neuromorphic chip may help engineers reach the exascale.

Interesting; especially since things have been very quite around IARPA and DARPA on their BMI efforts lately.

The Microns project aims to decipher the brain’s algorithms in an effort to revolutionize machine learning.

April 5, 2016, New York — People are using brain-machine interfaces to restore motor function in ways never before possible — through limb prosthetics and exoskletons. But technologies to repair and improve cognition have been more elusive. That is rapidly changing with new tools — from fully implantable brain devices to neuron-eavesdropping grids atop the brain — to directly probe the mind.

These new technologies, being presented today at the Cognitive Neuroscience Society (CNS) annual conference in New York City, are mapping new understandings of cognition and advancing efforts to improve memory and learning in patients with cognitive deficits.

Eavesdropping on neurons

“A new era” of electrophysiology is now upon us, says Josef Parvizi of Stanford University who is chairing the CNS symposium on the topic. “We have gotten a much sharper view of the brain’s electrophysiological activity” using techniques once relegated to science fiction.
