Startup touts neuro-stimulation as 'medicine for the brain'

The Japan Times

According to California startup Halo Neuroscience, the device can help improve the performance of athletes, pilots and surgeons, and potentially help rehabilitation for stroke victims. By stimulating the motor cortex, Chao says the Halo device can "extract latent potential" in the brain to improve performance for people who rely on making quick decisions and movements such as athletes. The San Francisco startup has also concluded deals with the San Francisco Giants baseball team and the U.S. Olympic ski team to integrate Halo in training programs. Chao, who trained as a doctor and studied neuroscience at Stanford, previously worked at a startup called Neuro Pace, which uses electrical stimulation to treat epilepsy.

Neurala has created patent-pending facial recognition software capable of working on very small computers, allowing it to be used on wearable devices. Neurala's founder, Massimiliano Versace, said the software works in a similar way to the mammalian brain, allowing it learn faster than traditional search technology.

'These organizations have formed teams to develop the fundamental research and component technologies required to pursue the NESD vision of a high-resolution neural interface and integrate them to create and demonstrate working systems able to support potential future therapies for sensory restoration,' official said. The team aims to apply techniques from the field of optogenetics to enable communication between neurons in the visual cortex and a camera-based, high-definition artificial retina worn over the eyes, facilitated by a system of implanted electronics and micro-LED optical technology. 'The NESD program looks ahead to a future in which advanced neural devices offer improved fidelity, resolution, and precision sensory interface for therapeutic applications,' said Phillip Alvelda, the founding NESD Program Manager. The program, Neural Engineering System Design (NESD), stands to dramatically enhance research capabilities in neurotechnology and provide a foundation for new therapies.


US Military: DARPA Grants $65 Million To Connect Human Brains With Digital Devices

International Business Times

A U.S. Military DARPA program is putting $65 million into the creation of an implantable device that will provide data-transfer between human brains and the digital world. The program seeks to heighten hearing, sight and other sensory perception as well as creating a digital brain implant to relay neuron transmissions directly to digital devices. DARPA's research team acknowledged that creating an interface and communicating with the signals of one million neurons "sounds lofty," but Alveda says their research will only map out a foundation for more complex research in the future. But if we're successful in delivering rich sensory signals directly to the brain, NESD will lay a broad foundation for new neurological therapies."

Henry Markram Talks Brain Simulation (IEEE Spectrum)

If we succeed in abstracting away the detailed molecular reactions while retaining a detailed, cellular-level resolution, human brain simulation comes much closer. We could also have reasonably high-resolution mouse brain models, and even higher resolution digital copies of the brains of birds, flies, bees, and ants. Only now are humans realizing that the human brain, as an organ belonging to an individual, already has superhuman capabilities: Every human brain embodies layers upon layers of knowledge and experience developed by all the other brains, present and past, who have contributed to building our societies, cultures, and physical environment. Furthermore, in the same way that the human brain embodies the physical and cultural world, it also embodies the technologies we create, including any artificial brains we may create.

Ans) Anterior prefrontal cortex has been associated with top-level processing abilities that are thought to set humans apart from other animals. Most of the gray-matter which plays the role in introspection exists in this region (right anterior prefrontal cortex, to be precise). This brain region has been implicated in planning complex cognitive behaviour, personality expression, decision making, and moderating social behaviour. Ans) Medial prefrontal cortex (mPFC) is considered to be a part of the brain's reward system.


Human brain structure inspires artificial intelligence

#artificialintelligence

The human brain is the most powerful supercomputer on Earth, and now researchers from the University of Southern California are taking inspiration from the structure of the human brain to make better artificial intelligence systems. Artificial intelligence (or AI) is a system of computing that aims to mimic the power of the human brain. "If we compare, for example, our brain to the super computers we have today, they run on megawatts, [which is] a huge amount of power that's equivalent to a few hundred households, while our brain only relies on water and sandwiches to function," said artificial intelligence and computing expert Han Wang from the University of Southern California said. It's this concept of running at low energy in parallel circuits.


Frighteningly accurate 'mind reading' AI reads brain scans to guess what you're thinking

What CMU scientists have been working on is a system that can apparently read complex thoughts based on brain scans, possibly even interpreting complete sentences. The discovery of this correspondence between thoughts and brain activation patterns tells us what the thoughts are built of." After training the algorithm on 239 of the 240 sentences and their corresponding brain scans, the researchers were able to predict the final sentence based only on the brain data. A paper describing the work, titled "Predicting the Brain Activation Pattern Associated With the Propositional Content of a Sentence," is published in the new issue of the journal Human Brain Mapping.
