Roadmap to human cortex scale neuromorphic hardware
It should be possible to build a silicon version of the human cerebral cortex with the transistor technology that was in production in 2013. The resulting machine would take up less than a cubic meter of space and consume less than 100 watts, not too far from the human brain. This article is summarizing the work of Jennifer Hasler and Bo Marr writing in Frontiers of Neuroscience – Finding a roadmap to achieve large neuromorphic hardware systems.
Computational power efficiency for biological systems is 8–9 orders of magnitude higher (better) than the power efficiency wall for digital computation. Analog techniques at a 10 nm node can potentially reach this same level of biological computational efficiency. Figure 1 show huge potential for neuromorphic systems, showing the community has a lot of room left for improvement, as well as potential directions on how to achieve these approaches with technology already being developed; new technologies only improve the probability of this potential being reached.
High-tech beanie could allow humans to achieve telepathy in a DECADE
A company is developing a device that can allow people to see inside their brains or bodies in great detail.
The technology, developed by Openwater, works via a piece of clothing such as ski-hat lined with LCDs – and, illuminated with infrared, it can see into your body to look for things such as tumors and bleeding or clogged arteries.
While the technology has significant potential for disease detection, the company’s ultimate aim is to develop it for communication via thought — in just eight years.
Isn’t Technological Singularity Just Backing Up Consciousness For Safe Keeping?
It’s amazing how fast science and emerging technologies are moving but most people seem to not care and want to break their emotional trance on trivial, emotional laden, propaganda filled news and views. Even though, this new science and emerging technology will have a profound effect on their lives and the lives of their children.
Human Extinction and using technological singularity and transhumanism to back up human consciousness to save and evolve the human race.
Scientists Assert They Will Soon be Able to Edit Human Memories
Researchers have recently discovered two different types of memory use completely different processes in the same nerves, opening the way for a new pharmaceutical solution for treating anxiety and post-traumatic stress disorder (PTSD).
The find challenges earlier research that had suggested memories of traumatic events used the same nerves in the same ways, making them impossible to physically distinguish.
A team of scientists from Columbia University Medical Center (CUMC) and McGill University analysed neurons from a marine snail called an Aplysia in order to test a hypothesis explaining why memories of incidents surrounding a bad experience can themselves trigger anxiety.
Harvard Researchers Succeed in Creating Telepathic Gateway Between Human and Rat Brain
Scientists are coming up with some very crazy experiments lately. Anything involving the human brain is always met with a fair bit of skepticism. However, a new project by Harvard researchers allows humans to control animals with their thoughts. It sounds quite impressive, although animal right activists may have concerns about this project. Regardless, a brain-to-brain interface could have some interesting consequences.
Revita Life Sciences Continues to Advance Multi-Modality Protocol in Attempt to Revive Brain Dead Subjects
Rudrapur, Uttrakhand, India — July 02, 2017
Revita Life Sciences, (http://revitalife.co.in) a biotechnology company focused on translational regenerative therapeutic applications, has announced that it is continuing to advance their novel, multi-modality clinical intervention in the state of brain death in humans.
“We have proactively continued to advance our multi-modality protocol, as an extended treatment before extubation, in an attempt to reverse the state of brain death” said Mr.Pranjal Agrawal, CEO Revita Life Sciences. “This treatment approach has yielded some very encouraging initial outcome signs, ranging from minor observations on blood pressure changes with response to painful stimuli, to eye opening and finger movements, with corresponding transient to permanent reversal changes in EEG patterns.”
This first exploratory study, entitled “Non-randomized, Open-labelled, Interventional, Single Group, and Proof of Concept Study with Multi-modality Approach in Cases of Brain Death Due to Traumatic Brain Injury Having Diffuse Axonal Injury” is ongoing at Anupam Hospital, Rudrapur, Uttrakhand. The intervention primarily involves intrathecal administration of minimal manipulated (processed at point of care) autologous stem cells derived from patient’s fat and bone marrow twice a week.
This study was inappropriately removed from the Indian Council of Medical Research (ICMR) database. ICMR has no regulatory oversight on such research in India.
The Central Drugs Standard Control Organization (CDSCO), Drug Controller General of India, had no objection to the program progressing. Regulatory approval as needed for new drugs, is currently not required when research is conducted on the recently deceased, although IRB and family consent is definitely required. CDSCO, the regulator of such studies, clearly states that “no regulatory requirements are needed for any study with minimal manipulated autologous stem cells in brain death subjects”.
Death is defined as the termination of all biological functions that sustain a living organism. Brain death, the complete and irreversible loss of brain function (including involuntary activity necessary to sustain life) as defined in the 1968 report of the Ad Hoc Committee of the Harvard Medical School, is the legal definition of human death in most countries around the world. Either directly through trauma, or indirectly through secondary disease indications, brain death is the final pathological state that over 60 million people globally transfer through each year.
“We are in process of publishing our initial retrospective results, as well ongoing early results, in a peer reviewed journal. These initial findings will prove invaluable to the future evolution of the program, as well as in progressing the development multi-modality regenerative therapeutics for the full range of the severe disorders of consciousness, including coma, PVS, the minimally conscious state, and a range of other degenerative CNS conditions in humans,” said Dr. Himanshu Bansal, Chief Scientific Officer, Revita Life Sciences and Director of Mother Cell.
With the maturation of the tools of medical science in the 21st century, especially cell therapies and regenerative medicines, tissues once considered irretrievable, may finally be able to be revived or rejuvenated. Hence many scientists believe that brain death, as presently defined, may one day be reversed. While the very long term goal is to find a solution for “re-infusing life”, the short term purpose of these types of studies is much less dramatic, which is to confirm if the current definition of brain irreversibility still holds true. There have been many anecdotal reports of brain death reversal across the world over the past decades in the scientific literature. Studies of this nature serve to verify and establish this very fact in a scientific and controlled manner. It will also one day give a fair chance to individuals, who are declared brain dead, especially after trauma.

I’m A Cyborg And So Are You
I have recently re-kindled my interest in neuro-hacking, the process of using technological and spiritual tools to essentially hack my consciousness, make myself calmer, and of course, happier! I’ve been using vitamins (D3!) and isochronic tones for some time, but I have run across a number of new devices and apps recently. I got a demo kit for a new device called Thync, that purports to alter brain waves to achieve greater calm, less stress, and more energy. This follows, for me, several decades of interest in this arena, also fueled by a bunch of projects in the works that seek to augment human potential using the latest brain science, emerging hardware, and games.
This is an area of professional interest as well as personal. I’m a socio-cultural anthropologist with a focus on digital culture, technology use, and future possibilities. My graduate work focused on social learning associated with online gaming. A lot of my focus falls into a sub-discipline of anthropology known as cyborg anthropology:
