Near-Death Experience Study: Brain Is Active After Death

Science media are making surprisingly few efforts to attack or explain away the team’s findings

A recent study led by near-death researcher Sam Parnia of the consciousness of patients whose hearts have stopped is providing more baseline data about the circumstances under which many near-death experiences occur. A team at the NYU Grossman School of Medicine, working with 25 hospitals mostly in the US and Britain, studied the “lucid death experiences” that can occur when heart attack survivors are apparently unconscious. Of 567 patients, only 53 (9.3%) survived. Most of them were flatlined, meaning that they had no brain activity at a certain point. Sometimes brain activity was restored as late as up to an hour later. Only 28 of them completed interviews. According to the media release for the open-access study, “Four in 10 Read More ›

We Need to Keep Medicine “Evidence-Based”

A new approach seems to be arriving — so-called science-based medicine. What is the difference?

We supposedly live in an era of “evidence-based medicine,” in which medical decisions are guided by the published data. But that approach is now being criticized because the “best evidence” is often in the eye of the beholder. A new approach seems to be arriving — so-called science-based medicine. What is the difference? It seems more than a mere shift in terminology, in that science-based medicine would allow fewer heterodox approaches than permitted by the evidence-based model. A new advocacy article, “Evidence-Based Medicine Is Broken but Science-Based Medicine Can Fix It,” published by the American Council on Science and Health (which claims to debunk “junk” in medicine), explains (emphasis in the original): The idea of evidence-based medicine has been around since Read More ›

CDC Neglects to Include Assisted Deaths in Official Suicide Report

Assisted dying is a form of suicide, regardless of the ways our culture has euphemized the term

2021 was among the worst years ever for suicides in the U.S., with 2022 looking to have been even worse. According to the CDC, in 2021, 48,183 people killed themselves. That number is projected to increase to 49,449 for 2022 once the data are tabulated. That’s a terrible tragedy. But it is even worse than that because assisted suicides are not included in the suicide statistics. Why? Because the laws legalizing assisted suicide in most states — which is euphemistically referred to as “medical aid in dying” (MAID) or “death with dignity” — redefine a doctor-prescribed overdose as other than what it is: suicide. Indeed, most of these laws require doctors to lie about the actual cause as the underlying disease Read More ›

Our Essential “I”ness … the Search for Its Address in the Brain

Does “I” — the first person singular — have or need a fixed address in the brain?

Neuroscience seems caught between a quest for the exact spot where self-awareness is generated and theorizing that self-awareness is really an illusion. A search for the spot in the brain that corresponds to “I” — as in Descartes’ famous formulation, “I think, therefore I am” begins with an assumption: That there is any such address in the brain. How is the search coming? Historically, we have located our sense of self in our hearts or heads. Both locations make sense, in different ways. Our hearts pound when we have strong feelings. As for our heads, it’s more complicated… When, in as-yet unpublished work, Christina Starmans and her colleagues showed people from the US and India pictures of flies circling around Read More ›

Is Dementia Research Missing the Forest for the Trees?

Sudden bouts of lucidity in people with dementia are understudied, researchers admit

Researchers have begun to ask about the curious fact that persons with obvious dementia sometimes have lucid episodes: “In the last week, Sarah has occasionally said things that were recognizable, startling her family. Most notably, on two occasions, she clearly and unexpectedly told her spouse, “I’m scared. I want you to come with me.” These episodes unsettled him. He reported them to Sarah’s physician, asking for advice. (This case is adapted from one of the author’s [JK] clinical experiences.)” – Peterson A, Clapp J, Largent EA, Harkins K, Stites SD, Karlawish J. What is paradoxical lucidity? The answer begins with its definition. Alzheimers Dement. 2022 Mar;18(3):513-521. doi: 10.1002/alz.12424. Epub 2021 Aug 2. PMID: 34338400; PMCID: PMC8807788. The paper is open Read More ›

How Can a Woman Missing Her Olfactory Bulbs Still Smell?

The brain’s plasticity intrigues and puzzles researcher, and it also raises a larger issue

Even since neuroscientists started imaging the brain, they’ve been turning up cases where people are missing brain parts we would expect them to need in order to do something — but they are doing that very thing anyway. One example, written up in LiveScience in 2019, concerns women who are missing their olfactory bulbs (illustrated) but can still smell: Researchers have discovered a small group of people that seem to defy medical science: They can smell despite lacking “olfactory bulbs,” the region in the front of the brain that processes information about smells from the nose. It’s not clear how they are able to do this, but the findings suggest that the human brain may have a greater ability to Read More ›

Patients Opting for Euthanasia in the Face of Painful Circumstances

Receiving assistance takes a long time. But to be made dead? Not so much.

So much compassion! A disabled woman with quadriplegia named Rose Finlay in Canada has asked to be euthanized because she is destitute, and the disability benefits she applied for would not arrive in time for her to be properly housed and cared for. From the CBC story: A quadriplegic woman in Bowmanville, Ont., has applied for medical assistance in dying (MAID), saying it’s easier to access than the support services she needs to live her life comfortably. Receiving assistance takes a long time. But to be made dead? Not so much: The single mother of three boys previously supported her family with earnings from disability advocacy work through her company, Inclusive Solutions. That’s also how she could afford to hire her own support Read More ›

This Country Just Legalized Euthanasia

The law isn't even limited to those who are terminally ill

Alas. The president of Portugal just signed into law a bill legalizing euthanasia by lethal injection. It is not limited to the terminally ill — which is at least honest, since that is not what euthanasia/assisted suicide is really all about. From the Reuters story: The law specifies that people would be allowed to request assistance in dying in cases when they are “in a situation of intense suffering, with definitive injury of extreme gravity or serious and incurable disease.” It establishes a two-month gap between accepting a request and the actual procedure and makes psychological support mandatory. Strict guidelines and all that jazz. Not only are they unlikely to be strictly enforced but will soon be redefined from protections to barriers, Read More ›

Synthetic Biology: What New Therapies Are in Store?

For today's featured video from COSM 2022, watch Babak Parviz, Vice President at Amazon, lead a discussion on synthetic biology

For today’s featured video from COSM 2022, watch Babak Parviz, Vice President at Amazon, lead a discussion on synthetic biology, the multi-disciplinary field that applies engineering principles to redesign biological systems for new purposes. The panel focuses on bio-medical technologies that hold great promise for curing diseases and even counteracting human aging. For more material on the topic, see this piece on Altos Labs and their work on bio-longevity. Part of their project also involves artificial intelligence research: Altos Labs’ vision isn’t too far removed from that of the transhumanists who want to computerize human consciousness. For them, however, longevity is a junior varsity goal — what we really need is a way to live forever. Harrison quips at the Read More ›

Mental health: Psychotherapy and Drugs Help Different Brain Areas

Camilla Nord reports that psychotherapy changed aspects of the brain’s prefrontal cortex whereas medications affected the amygdala

Whether to treat mental health issues with psychotherapy or drugs has sometimes led to pitting one against the other. For example, as Cambridge neuroscientist Camilla Nord has noted, in a report that no longer seems to be online, the British Psychological Society’s Division of Clinical Psychology stated in 2016 that “There is no firm evidence that mental distress is primarily caused by biochemical imbalances, genes, or something going wrong in the brain …” Rather, the Society cited childhood trauma, abuse, and poverty as causes, to be remedied by political and social change. Other studies (here is a systematic review) found the same thing. Nord responds that mental disorders are brain disorders. However, she does not resort to simplistic claims that Read More ›

Is Depression an Altered Global State of Consciousness?

Cecily Whiteley and Jonathan Birch from the London School of Economics and Political Science argue that altered consciousness prevents depressed people from just "seeing the bright side"

PhD student Cecily Whiteley and philosophy prof Jonathan Birch, both of the London School of Economics and Political Science, think that depression is often misunderstood. In this 2021 article, noted again at Psyche, they point out that it is not just “feeling low”; it is an altered form of consciousness: The psychologist Andrew Solomon hints at some of these transformations in his memoir The Noonday Demon (2001): “When you are depressed, the past and future are absorbed entirely by the present moment, as in the world of a three-year-old. You cannot remember a time when you felt better, at least not clearly; and you certainly cannot imagine a future time when you will feel better. Being upset, even profoundly upset, Read More ›

China’s Foxconn Walkout: How Fear Messaging Can Backfire

Workers were caught in a conflict between unrealistic COVID Zero messaging from the government and seasonal performance demands from the employer

Around this time of year, the factories that produce Apple’s iPhones hire thousands of additional workers to meet the demand for the holiday season. While Apple is an American company and the electronics are designed in-house, the manufacturing is done overseas where labor costs are cheaper. One of the largest manufacturers for Apple’s iPhone products is Hon Hai Technology Group, better known as Foxconn, a Taiwan-based company with factories in several countries, including mainland China. One of its largest facilities is in Zhengzhou, the capital of Henan province — dubbed “iPhone City” by the locals. Thus the Zhengzhou Foxconn factory was slated to make 80% of the iPhone 14 models and 85% of the iPhone Pro models before the end Read More ›

Lab Leak Theory: A Biohazard Was First Noted in 2019

The dispatches indicate a “grave and complex situation” prompting an emergency visit from the director of the Chinese Academy of Sciences

A US Senate interim report has recently concluded that that “the Covid-19 pandemic was, more likely than not, the result of a research-related incident.” The 35-page report, prepared by the minority oversight staff of the of the Senate Committee on Health, Education, Labor, and Pensions (HELP), used publicly available documentation to justify the findings. However, it did not include the 236-page report submitted by language expert Toy Reid, who analyzed Chinese Communist Party dispatches between scientists at the Wuhan Institute of Virology (WIV) and their supervisors in Beijing. Katherine Eban of Vanity Fair and Jeff Kao of ProPublica were given advanced access to the Senate researchers’ documents and spent months conducting their own investigation. They interviewed Reid, talked with members Read More ›

How Fact-Checking Can Hide Needed Information From the Public

What role did fact-checking play in the suppression of inconvenient but essential facts about the origin of COVID-19?

Earlier this week, we looked at the recent news that Facebook has a special portal for government to look in and report “disinformation,” — as if government, in a highly charged political atmosphere, were some kind of neutral third party. The assignment of some sort of neutrality to power sources or experts who may not be neutral or have any reason to be is one of the characteristics of fact-checking, as it has developed over the last decade in mainstream and social media. Why was the Wuhan lab leak theory supposed to be a conspiracy? In that context, let’s look at the claim that COVID-19 originated in an accident at a high-level virus lab in the upcountry Chinese city of Read More ›

Study: Loss of Half the Brain Doesn’t Mean No Word, Face Contact

Researchers astounded: Contrary to theory, in a recent study, the single remaining brain hemisphere supported both word and face reading functions

Some children have half of their brains removed (hemispherectomy) to control massive seizures that would otherwise destroy the child’s whole brain. Specialists were surprised that the children functioned fairly normally — certainly compared to what would have been expected. A recent study of post-hemispherectomy patients has provided dramatic evidence of rewiring: An unprecedented study of brain plasticity and visual perception found that people who, as children, had undergone surgery removing half of their brain correctly recognized differences between pairs of words or faces more than 80% of the time. Considering the volume of removed brain tissue, the surprising accuracy highlights the brain’s capacity — and its limitations — to rewire itself and adapt to dramatic surgery or traumatic injury.

Placebo: The Power of the Human Mind Confounds Medical Research

Angelman syndrome, which creates a variety of developmental problems, has proven a challenge for researchers on that account

We don’t often hear about researchers crying but when researchers at Ovid Therapeutics heard the test results for their drug, gaboxadol, they couldn’t help it. They were testing the sleep-inducing drug to help with the symptoms of Angelman Syndrome, a rare neurogenetic disorder that appears in infancy. It results in a variety of developmental problems such as walking and balance disorders, inability to speak or sleep properly, gastrointestinal issues, and seizures. It affects people in different ways and to different degrees. Notably, those who cope with Angelman smile and laugh a lot and have a normal lifespan. The OVID team had high hopes for gaboxadol in August of this year because even improving the quality of sleep would help sufferers Read More ›
