Drug beliefs produce a dose-dependent effect in the brain, study finds
By Paul McClure A study has found that a person’s drug beliefs can produce a dose-dependent effect in the brainDepositphotos Researchers have shown, for the first time, that a person’s beliefs about nicotine influences brain activity, producing a dose-dependent effect that was only thought to occur with pharmaceutical agents. In addition to providing an explanation for...

Study identifies new concepts for GLP-1 action in the brain
by Lunenfeld-Tanenbaum Research Institute Graphical abstract. Credit: Cell Metabolism (2023). DOI: 10.1016/j.cmet.2023.11.009 Researcher Dr. Daniel Drucker has much to be proud of, as the GLP-1-based diabetes drugs hailing from his early research are named the 2023 breakthrough of the year by the Science Magazine. Not only have millions of people with type 2 diabetes benefitted from...

Riding Sound Waves in the Brain
ETH Zurich researchers have shown for the first time that microvehicles can be steered through blood vessels in the brains of mice using ultrasound. They hope this will eventually lead to treatments capable of precisely delivering drugs.Neuroscience, brain – associative rendering. Neuroscience, brain – associative rendering.

Our Brains Are Not Able to ‘Rewire’ Themselves, Despite What Most Scientists Believe, New Study Argues
Contrary to the commonly-held view, the brain cannot rewire itself to compensate for the loss of sight, an amputation or stroke, for example, say scientists from the University of Cambridge and Johns Hopkins University. Graphic representing brain circuits. Credit: GDJ, Public Domain Writing in eLife, Professors Tamar Makin (Cambridge) and John Krakauer (Johns Hopkins) argue...

New study is first to find brain hemorrhage cause other than injured blood vessels
by University of California, Irvine t-BHP-treated RBC stall in cerebral blood vessels and impair cerebral blood flow velocity shown by in vivo high-resolution two-photon imaging in mice. Schematic of the experimental design (A). RBC were collected from FVB/NJ mice, treated with control PBS or the oxidative stressor t-BHP, then labeled with the PKH26 fluorescent dye...

Pain, fatigue, fuzzy thinking: How long COVID disrupts the brain
November 13 Jon Hamilton Scientists are learning more about how long COVID affects the brain.Michelle Wilson got COVID three years ago. She’s still waiting for her brain and nervous system to recover. Wilson’s memory is spotty, she’s frequently in pain, and even a short walk leaves her exhausted. “I actually bought a cane that turns...

AHA Reviews Impact of Aggressive LDL Lowering on the Brain
Megan Brooks A newly published scientific statement from the American Heart Association (AHA) focuses on the impact of aggressive low-density lipoprotein cholesterol (LDL-C) lowering on the risk for dementia and hemorrhagic stroke. “The brain is the body’s most cholesterol-rich organ, and some have questioned whether aggressive LDL-C lowering induces abnormal structural and functional changes,” the...

Probiotics delivered in biofilm state protect the intestines and brain in NEC model
Biofilm formulation of Limosilactobacillus reuteri protects against necrotizing enterocolitis in piglet model Peer-Reviewed Publication NATIONWIDE CHILDREN’S HOSPITAL (COLUMBUS, Ohio) – Necrotizing enterocolitis (NEC) is a debilitating and deadly condition that affects infants who were born preterm. In NEC cases, intestinal tissues become inflamed, and in severe cases there is ischemia and death of the involved...
