Neuromorphic computing is coming, and it’s based on the way the brain works. In this installment of Brains Behind the Brains, Mike Davies, Director of Neuromorphic Computing at Intel Labs, talks to us about this technology, Intel’s Loihi processors, and how neuromorphic computing will change our world in wonderful ways. https://intel.ly/3hmL0Ip.

About Intel:
Intel, the world leader in silicon innovation, develops technologies, products and initiatives to continually advance how people work and live. Founded in 1968 to build semiconductor memory products, Intel introduced the world’s first microprocessor in 1971. This decade, our mission is to create and extend computing technology to connect and enrich the lives of every person on earth.

MEXICO CITY (Reuters) — Mexican authorities said they are studying the case of a 32-year-old female doctor who was hospitalized after receiving the Pfizer-BioNTech COVID-19 vaccine.

The doctor, whose name has not been released, was admitted to the intensive care unit of a public hospital in the northern state of Nuevo Leon after she experienced seizures, difficulty breathing and a skin rash.

“The initial diagnosis is encephalomyelitis,” the Health Ministry said in a statement released on Friday night. Encephalomyelitis is an inflammation of the brain and spinal cord.

Shared last year, but with the talk of future regenerative medicine I think it is important: Regenerative medicine aims to engineer tissue constructs that can recapitulate the functional and structural properties of native organs. Most novel regenerative therapies are based on the recreation of a three-dimensional environment that can provide essential guidance for cell organization, survival, and function, which leads to adequate tissue growth. The primary motivation in the use of conductive nanomaterials in tissue engineering has been to develop biomimetic scaffolds to recapitulate the electrical properties of the natural extracellular matrix, something often overlooked in numerous tissue engineering materials to date. In this review article, we focus on the use of electroconductive nanobiomaterials for different biomedical applications, particularly, very recent advancements for cardiovascular, neural, bone, and muscle tissue regeneration. Moreover, this review highlights how electroconductive nanobiomaterials can facilitate cell to cell crosstalk (i.e., for cell growth, migration, proliferation, and differentiation) in different tissues. Thoughts on what the field needs for future growth are also provided.

Summary: Treatment with LAU-0901, a synthetic molecule that blocks pro-inflammatory platelet-activating factor, in addition to aspirin-triggered NPD1, reduced the size of damage areas in the brain, initiated repair mechanisms, and improved behavioral recovery following ischemic stroke.

Research conducted at LSU Health New Orleans Neuroscience Center of Excellence reports that a combination of an LSU Health-patented drug and selected DHA derivatives is more effective in protecting brain cells and increasing recovery after stroke than a single drug.

A pair of monkeys were able to “see” and recognize individual letter shapes generated by arrays of electrodes implanted in their brains – without using their eyes. Previously, sight-restoring implants were placed in the retina, but these new implants were placed in the visual cortex. They achieved the highest resolution yet for such technology.

The research took place at the Netherlands Institute for Neuroscience (NIN). The scientists wanted to develop a way to restore sight for people whose optic nerves were damaged and couldn’t benefit from retina implants. The team, led by Pieter Roelfsema, created a brain implant made of needle-like electrodes 1.5 millimeters in length. They placed it on the animals’ visual cortex, partially restoring its sight.

The visual cortex is like a cinema screen in our skull, with each area on its surface mapping to the visual field. Placing a patch of electrodes on the surface that activate like pixels will make a person “see” whatever points get activated. For example, if an L-shaped pattern of electrodes in contact with the visual cortex is activated, they will see a pixelated L.

Dr. Nicole Prause, PhD is an American neuroscientist researching human sexual behavior, addiction, and the physiology of sexual response. She is also the founder of Liberos LLC, an independent research institute and biotechnology company.

Dr. Prause obtained her doctorate in 2007 at Indiana University Bloomington, with joint supervision by the Kinsey Institute for Research in Sex, Gender, and Reproduction, with her areas of concentration being neuroscience and statistics. Her clinical internship, in neuro-psychological assessment and behavioral medicine, was with the VA Boston Healthcare System’s Psychology Internship Training Program. Her research fellowship was in couples’ treatment of alcoholism was at Harvard University.

Dr. Prause became a tenure track faculty member at Idaho State University at the age of 29. After three years there, she accepted a position as a Research Scientist at the Mind Research Network, a neuro-imaging facility in Albuquerque, New Mexico.

In 2012, Dr. Prause was elected a full member of the International Academy of Sex Research and accepted a position as a Research Scientist on faculty at the University of California, Los Angeles in the David Geffen School of Medicine. While there, she was promoted to Associate Research Scientist in 2014.
