Researchers Discover Mechanism by which Estrogen can Trigger Fast Neuronal Responses

Posted by in categories: biotech/medical, neuroscience

Estrogen, the major female ovarian hormone, can trigger nerve impulses within milliseconds to regulate a variety of physiological processes. At Baylor College of Medicine, Louisiana State University and collaborating institutions, researchers discovered that estrogen’s fast actions are mediated by the coupling of the estrogen receptor-alpha (ER-alpha) with an ion channel protein called Clic1.

Clic1 controls the fast flux of electrically charged chloride ions through the cell membrane, which neurons use for receiving, conducting and transmitting signals. The researchers propose that interacting with the ER-alpha-Clic1 complex enables estrogen to trigger fast neuronal responses through Clic1 ion currents. The study appears in Science Advances.

“Estrogen can act in the brain to regulate a variety of physiological processes, including female fertility, sexual behaviors, mood, reward, stress response, cognition, cardiovascular activities and body weight balance. Many of these functions are mediated by estrogen binding to one of its receptors, ER-alpha,” said co-corresponding author Dr. Yong Xu, professor of pediatrics—nutrition and associate director for basic sciences at the USDA/ARS Children’s Nutrition Research Center at Baylor.

Michael Levin — Why Intelligence Isn’t Limited To Brains

Posted by in categories: biological, neuroscience

Professor Michael Levin explores the revolutionary concept of diverse intelligence, demonstrating how cognitive capabilities extend far beyond traditional brain-based intelligence. Drawing from his groundbreaking research, he explains how even simple biological systems like gene regulatory networks exhibit learning, memory, and problem-solving abilities. Levin introduces key concepts like “cognitive light cones” — the scope of goals a system can pursue — and shows how these ideas are transforming our approach to cancer treatment and biological engineering.

Breakthrough Discovery: Freezing Alzheimer’s Progress by Pausing Amyloid Fibrils

Posted by in categories: biotech/medical, neuroscience

Researchers have identified a key mechanism in the development of Alzheimer’s disease involving the growth and pause of amyloid β fibrils.

A newly discovered antibody can lock these fibrils in their paused state, offering a potential new approach for treatment that targets these critical growth points.

Scientists Revived a Pig’s Brain Nearly a Whole Hour After It Died

Posted by in category: neuroscience

Scientists have revived activity in the brains of pigs up to nearly an hour after circulation had ceased.

In some cases, functionality was sustained for hours through a surprising discovery by researchers in China.

Philosophy and Neuroscience

Posted by in category: neuroscience

From the reviews:

“If you thought reductionism about the mind was dead, think again: you may find John Bickle’s vigorously and powerfully argued Philosophy and Neuroscience: A Ruthlessly Reductive Account a real eye-opener. His guiding idea is that the proof of reductionism is in the track record of reductionist research strategies in neuroscience, in explaining mentality and behavior — and even qualitative consciousness itself. And Bickle does not disappoint: he serves up a veritable feast of reductionist success stories, from deep down in cellular and molecular neuroscience. Some of the details he describes will amaze, and perhaps also delight, you. Bickle’s discussion is invigorating as well as philosophically sophisticated, and his knowledge of current research in neuroscience is impressive indeed. The writing is clear, brisk, and refreshingly straightforward, and the book brims with enthusiasm and optimism. This is the latest salvo from the reductionist side, and a mighty one it is! It may not win the battle outright for reductionism, but it is going to change the shape and terms of the debate to come. A must read for those interested in the issues of psychoneural reduction and reductionism, and highly recommended to anyone with a broad interest in the philosophy of mind and psychology.” (Jaegwon Kim, Brown University)

“Bickle now practices metascience … a large part of the book consists of neuroscientific case studies. … Bickle’s experimental cases are fascinating and his book qualifies as a showcase of naturalism in the philosophy of mind. As such it deserves to be read by any philosopher with naturalistic leanings. … Bickle has provided food for thought. … It manifests a profound respect for empirical developments, and a healthy criticism of philosophical hobbyhorses and entrenched reasoning patterns. This makes the book worthwhile reading.” (Huib Looren de Jong and Maurice K. D. Schouten, PhilosophicalPsychology, Vol. 18 , 2005)
