The Physics of Belief: Placebo Effects as Quantum Psychosomatics and the Material Reality of Meaning

Read “” by Myk Eff on Medium.


When a patient in a clinical trial experiences genuine pain relief from an inert sugar pill, something remarkable occurs that contemporary medicine awkwardly labels the placebo effect — a term that simultaneously acknowledges the phenomenon while dismissing it as mere illusion. Yet what if this dismissal represents not scientific rigor but ontological timidity? What if the placebo effect, rather than being a confounding variable to be controlled away, is actually nature’s clearest demonstration of a quantum interface between consciousness and physiology, hiding in plain sight within the very architecture of our clinical trials? The question is not whether belief heals, but what belief actually is when we take seriously the contemporary understanding that information itself possesses physical reality.

The empirical robustness of placebo effects has become impossible to ignore. In their comprehensive meta-analysis published in The Lancet, Hróbjartsson and Gøtzsche (2001) examined 114 clinical trials and found that while placebo effects vary considerably across conditions, they demonstrate genuine clinical significance in pain reduction, with effect sizes rivaling those of established pharmaceutical interventions. More provocatively, Benedetti’s research on placebo analgesia has revealed that the effect operates through identifiable neurochemical pathways — placebo-induced pain relief can be blocked by naloxone, an opioid antagonist, demonstrating that the patient’s belief literally triggers the release of endogenous opioids (Benedetti, Mayberg, Wager, Stohler, & Zubieta, 2005). This is not imagination overriding reality; this is imagination as a physical force, translating expectation into molecular cascade.

Yet the standard neurobiological explanation, while accurate, remains curiously incomplete. Yes, belief activates specific neural circuits; yes, these circuits trigger biochemical responses; yes, measurable physiological changes occur. But this mechanistic account merely pushes the mystery one level deeper. How does the abstract informational content of a belief — the semantic meaning this pill will relieve my pain — couple to the physical substrate of neurons and neurotransmitters? The conventional answer invokes learning, conditioning, and expectation, but these terms describe the phenomenon without explaining the fundamental ontological transition from meaning to matter, from information to effect.

A Common Sleeping Pill May Reduce Buildup of Alzheimer’s Proteins, Study Reveals

There’s still so much we don’t know about Alzheimer’s disease, but the link between poor sleep and worsening disease is one that researchers are exploring with gusto.

A study published in 2023 found that using sleeping pills to get some shut-eye could reduce the buildup of toxic clumps of proteins in fluid that washes the brain clean every night.

People who took suvorexant, a common treatment for insomnia, for two nights at a sleep clinic experienced a slight drop in amyloid-beta and tau, two proteins that pile up in Alzheimer’s disease.

Quantifying the compressibility of the human brain

In the human brain, the allowed patterns of activity are constrained by the correlations between brain regions. Yet it remains unclear which correlations—and how many—are needed to predict large-scale neural activity. Here, we present an information-theoretic framework to identify the most important correlations, which provide the most accurate predictions of neural states. Applying our framework to cortical activity in humans, we find that the vast majority of variance in activity is explained by a small number of correlations. This means that the brain is highly compressible: Only a sparse network of correlations is needed to predict large-scale activity. We find that this compressibility is strikingly consistent across different individuals and cognitive tasks and that, counterintuitively, the most important correlations are not necessarily the strongest.

Flavanols Break the Rules of Nutrition: Scientists Uncover the Surprising Way They Boost the Brain

The health benefits of dietary flavanols appear to come from their ability to trigger responses in the brain and the body’s stress systems. That slightly dry, tightening feeling some foods leave in the mouth is known as astringency, and it comes from naturally occurring plant compounds called pol

Taming Tumor Chaos: Researchers Uncover Key to Improving Glioblastoma Treatment

A groundbreaking study from Brown University Health researchers has identified a crucial factor that may help improve treatment for glioblastoma, one of the most aggressive and common forms of adult brain cancer. The findings, published November 10 in Cell Reports, reveal how differences among cells within a single tumor influence the cancer’s response to chemotherapy, and introduce a promising new therapy designed to tip the odds in the patients’ favor.

Glioblastoma is notoriously difficult to treat. One of the key reasons is that no two cells within the tumor behave exactly alike. Even inside one tumor, some cells may respond to treatment while others resist it, allowing the cancer to persist and grow. For decades, scientists have known that tumors are composed of diverse cells, but the biological forces driving these differences, and their impact on treatment, have remained elusive.

“Traditionally, researchers have focused on the overall behavior of a tumor by studying the average response across all the individual cells, using differences between the cells to interpret the average,” said senior author Clark Chen, MD, PhD, professor and director of the brain tumor program, department of neurosurgery at Brown University Health. “Our study fundamentally flipped that approach. Rather than focusing on the average response, we focused on the differences between individual cells within the same tumor, and what we found could change how we treat glioblastoma.”

Bacterial ‘brains’ operate on the brink of order and disorder

The sensory proteins that control the motion of bacteria constantly fluctuate. AMOLF researchers, together with international collaborators from ETH Zurich and University of Utah, found out that these proteins can jointly switch on and off at the same time. The researchers discovered that this protein network operates at the boundary between order and disorder. The findings are published in Nature Physics on January 29.

Bacteria may be simple, single-celled organisms, but they still have a surprisingly sophisticated way of sensing and responding to their environment. Tom Shimizu, group leader at AMOLF and senior author of the study, explains that bacteria use networks of thousands of proteins to judge whether conditions are improving or worsening.

Lab grown mini human brains have been given blood vessels for the first time 🧠

These mini brain organoids resemble the developing cortex — the area of our brains that think, feel and store memories.

This advancement will help us learn more about conditions like dementia, but what if we go too far and they become conscious?
