How to Make a Consciousness Meter

Posted by in categories: information science, neuroscience

Yes, you can detect another person’s consciousness. Christof Koch described a method called ‘zap and zip’. Transcranial magnetic stimulation is the ‘zap’. Brain activity is detected with an EEG and analyzed with a data compression algorithm, which is the ‘zip’. Then the value of the perturbational complexity index (PCI) is calculated. If the PCI is above 0.31 then you are conscious. If the PCI is below 0.31 then you are unconscious. If this link does not work then go to the library and look at the November 2017 issue of Scientific American. It is the cover story.


Zapping the brain with magnetic pulses while measuring its electrical activity is proving to be a reliable way to detect consciousness.

Aging and Stem Cells | Theodore Ho | TEDxMiddlebury

Posted by in categories: bioengineering, biotech/medical, genetics, life extension, nanotechnology, neuroscience

Dr. Theodore Ho talks about the rapidly expanding possibilities of stem cells to be used in reversing or slowing the aging process. He discusses his previous and current work with the brain, including such methods as tissue clearing, multifiber photometry and optogenetics, and single resolution calcium imaging and control. Dr. Ho is a neuroscientist and stem cell biologist studying the mechanisms and causes of biological aging and potential strategies to slow or reverse them, in order to prevent the onset of age

Associated diseases to help us live healthier and longer lives.

Going mobile: FDA clears world’s first bedside MRI scanner-on-wheels

Posted by in categories: biotech/medical, neuroscience

The FDA has cleared the world’s first portable MRI system, designed to be wheeled to a hospital bedside for scanning a patient’s head and brain.

Developed by Hyperfine Research for people age two and older, the point-of-care imaging system weighs about one-tenth that of a conventional, fixed MRI system. About three feet wide and five feet tall, the device fits in an elevator and runs off an everyday power outlet to create both clinical contrast images and 3D renders.

“More than 40 years after its first use, MRI remains a marvel. Unfortunately, it also remains inaccessible,” Hyperfine Chief Medical Officer Khan Siddiqui said in a statement. “It’s time that MRI made the jump to point of need just like X-ray and ultrasound have before it.”

Scientists find ally in fight against brain tumors: Ebola

Posted by in categories: biotech/medical, neuroscience

Glioblastomas are relentless, hard-to-treat, and often lethal brain tumors. Yale scientists have enlisted a most unlikely ally in efforts to treat this form of cancer — elements of the Ebola virus.

“The irony is that one of the world’s deadliest viruses may be useful in treating one of the deadliest of brain cancers,” said Yale’s Anthony van den Pol, professor of neurosurgery, who describes the Yale efforts Feb. 12 in the Journal of Virology.

The approach takes advantage of a weakness in most cancer tumors and also of an Ebola defense against the immune system response to pathogens.

Grateful Dead Drummer’s Quest to End Alzheimer’s

Posted by in categories: biotech/medical, media & arts, neuroscience

Hart’s demonstrations are entertainment for sure. But his message runs deeper: rhythm and vibration heal the brain. Dementia, he says, is the “loss of rhythm.” And he, along with notables who collaborated on the event — University of California at San Francisco neuroscientist Adam Gazzaley and opera singer Renée Fleming (who lent her soprano to the event’s musical track) — are all at work searching for pathways that can bypass obstacles to function and cognition. Hart has also worked with Dr. Connie Tomaino, who runs the Institute for Music and Neurologic Function, on music as a therapeutic tool for brain function.

Gazzaley is currently conducting clinical trials with healthy older adults to show how a regular regimen of digital rhythm can enhance attention and memory in people with cognitive impairment. Hart has been working with Gazzaley on what will be a downloadable app, their goal to develop a game that challenges one’s rhythmic ability, with the hope of building new neuropathways in the brain. “What we’re talking about here is a deeper and longer immersive experience which can actually harness the brain’s plasticity to change the way it functions,” says Gazzaley.

Taking up an instrument as a child, and playing through adulthood is one proven way to protect one’s brain. But learning later in life is helpful, too. Hart shares the story of his unlikely best friend, Walter Cronkite, who was 73 when he became a Deadhead, and also started playing the drums. In July of 2009, as Cronkite lay dying from complications of cerebrovascular disease, Hart handed him a hand drum. “He could no longer speak, but he could play,” Hart says, tears in his eyes. “He used to ask, ‘When we do we know we have found our groove?’ Well, he found it.”

Can art be effective medicine for treatment of mental and physical illness?

Posted by in categories: biotech/medical, education, health, neuroscience

Yes! In this video with my dear friend, artist Nicholas Wilton, I review the scientific data linking creativity and disease remission from Mind Over Medicine. Plus, Nick reads the quote he wrote in Brene Brown’s Daring Greatly about art-making as treatment for perfectionism. If you or someone you love has been hoping to become a “health outlier” who experiences a better than usual outcome from a health struggle, or if you just love art and want to improve your art-making as part of your prescription for optimal health and a vital, fully expressed life, we hope this will offer you inspiration—and a few medicinal laughs! (As an OB/GYN, I couldn’t resist drawing the female reproductive systems when we got to the art-making part.)

Nick will be teaching a wonderful free online art class ART 2 LIFE that starts on Valentine’s Day, so give yourself this gift of your love of art-making. You can sign up for the free course here. https://share.tellafrienda2l.com/a/a2lworkshop/LissaR

Childhood brain tumor discovery may unlock new treatments for many cancers

Posted by in categories: biotech/medical, neuroscience

“” This cancer seems simple. Basically, it has been known for many years it is just one type of cells that proliferate out of control,” Zong said. “However, we noticed an interesting paradox. While tumor cells grow really fast in the body, they grow poorly and only for a limited time when we take them out and put them in a [lab] dish. So we suspected some other cells may be in play.”

His investigation of that suspicion turned science’s understanding of medulloblastoma on its head. Using an innovative model of the disease, Zong and his team marked tumor cells so that they would appear green. That led to the first surprise: While all other cell types outside the tumor are colorless, a cell type called astrocyte appeared green, which never happens in normal brain regions.

“Astrocyte actually has been linked to poor prognosis of medulloblastoma, but nobody has ever suspected its origin, since the cell of origin for medulloblastoma normally never gives rise to astrocytes. The fact that tumor-associated astrocytes share the same color with tumor cells suggests that they actually come from tumor cells,” he said. “So some tumor cells basically completely change their identity to make a separate cell type.”
