SAN CARLOS, Calif., Feb. 19, 2020 /PRNewswire/ — ZAP Surgical Systems, Inc. today announced an agreement with Bonifatius Hospital in Lingen, Germany to acquire ZAP-X® stereotactic radiosurgery (SRS) technology.
SRS is a well-known and effective procedure for non-invasively treating select brain tumors and brain metastases. However, significant acquisition and radiation shielding costs of historical SRS systems have limited widespread access to this potentially life-saving therapy. Consequently, scarce availability of SRS treatment has remained heavily concentrated in large urban hospitals.
If you think you control your own thoughts and decisions, think again. Recent research reveals that unconscious thoughts give birth to our mental imagery and personal choices.
Summary: Repetitive transcranial memory stimulation applied to the dorsolateral prefrontal cortex modifies the negative effects of fear memories. The findings could have implications for the treatment of PTSD.

A research group from the University of Bologna has succeeded in modifying the negative effect of a returning memory that triggers fear, and developed a new non-invasive experimental protocol. The result of this study, published in the journal Current Biology, is an innovative protocol that combines fear conditioning—a stimulus associated with something unpleasant that induces a negative memory—and the neurostimulation of a specific site of the prefrontal cortex.
When we say someone has a quick mind, it may be in part thanks to our expanded cerebellum that distinguishes human brains from those of macaque monkeys, for example.
Sometimes referred to by its Latin translation as the ‘“little brain”’, the cerebellum is located close to the brainstem and sits under the cortex in the hindbrain. New research at San Diego State University, however, calls the “little” terminology into question.
The cerebellum plays a versatile role, contributing to our five senses as well as pain, movements, thought, and emotion.
Summary: Activating p38gamma, a naturally protective enzyme in the brain, may help to prevent the development of Alzheimer’s disease symptoms. Researchers showed the naturally protective effects of p38gamma could be harnessed to improve memory in the later stages of Alzheimer’s disease.

A lone genetic mutation can cause a life-changing disorder with effects on multiple body systems. Lysosomal storage diseases, for example, of which there are dozens, arise due to single mutations that affect production of critical enzymes required to metabolize large molecules in cells. These disorders affect multiple organs including, notably, the brain, causing intellectual disability of varying degrees.
The discovery could lead to long lasting brain implants that can both treat neurological disease and enable mind controlled prosthetics and machines.
A group of researchers from the University of Michigan has created a new ultra-low-power brain implant. The scientists say that the estimated reduction in power requirements is about 90% for their new creations. Not only have they reduced the power requirements for the implants, they have also made them more accurate.

I have only been aware of this DARPA NNN (Next-generation Non-surgical Neurotechnology) program since mid-March, and it is my number one topic of interest. I am interested in it because I have a plan for mind uploading to extend my life indefinitely — otherwise known as superlongevity in our group — but I have no interest in allowing anyone to drill holes in my head! DARPA is looking at ways for non-invasive methods of connecting the thoughts in our brains to computers. Over time, this could be a method to capture the thoughts and memories and emotions within my mind and transfer them into a computer substrate. And, to be clear, this mind upload will, in fact, be me.
Naturally, DARPA is not developing this so that I can upload my mind. This is part of their wounded warrior project, where they are trying to rehabilitate soldiers who have had the misfortune to have lost a limb. In addition to the non-invasive neural technology, they are working on haptics to provide a feedback loop for the sense of touch and temperature. They are also working on what they describe as third wave AI to support this technology.
The interview is with Dr Al Emondi, who has had a fascinating career in technology. He is the DARPA program manager in the Biological Technologies department.
I will always admire DARPA for its world-changing technology innovations!
Through a cross-species study of metformin, a common drug used to treat Type 2 diabetes, a team of researchers and clinicians from the Donnelly Center and The Hospital for Sick Children (SickKids) has shown that it could one day be possible to repair brain injury using resident cells in the brain.
“No one’s actually shown before that you can take a drug where there’s a known mechanism on endogenous stem cells and demonstrate that it’s even possible to induce brain growth and positive recovery,” says Donald Mabbott, Program Head and Senior Scientist in the Neurosciences & Mental Health program at SickKids, and co-author of a study published in Nature Medicine on July 27.
Mabbott says metformin is a potential game-changer in terms of how childhood brain injury is treated.
Summary: First responders at the World Trade Center have reduced cortical gray matter thickness, which was consistent with neurodegenerative conditions and evidence their brain age is, on average, ten years older than those of similar ages in the general population.

Two studies led by Stony Brook University researchers to be presented virtually at the Alzheimer’s Association International Conference on July 28, 2020, indicate that World Trade Center (WTC) first responders are at risk for developing dementia. The studies included individuals with signs of cognitive impairment (CI) who show neuroradiological abnormalities and changes in their blood similar to that seen in Alzheimer’s disease patients and those with related dementias.
