“Mini-Brains” Grown in a Lab Provide Clues About Early Life Origins of Schizophrenia

Posted by in categories: biotech/medical, genetics, neuroscience

Multiple changes in brain cells during the first month of embryonic development may contribute to schizophrenia later in life, according to a new study by Weill Cornell Medicine investigators.

The researchers, whose study was published in Molecular Psychiatry, used stem cells collected from patients with schizophrenia and people without the disease to grow 3-dimensional “mini-brains” or organoids in the laboratory. By comparing the development of both sets of organoids, they discovered that a reduced expression of two genes in the cells stymies early development and causes a shortage of brain cells in organoids grown from patient stem cells.

“This discovery fills an important gap in scientists’ understanding of schizophrenia,” said senior author Dr. Dilek Colak, assistant professor of neuroscience at the Feil Family Brain and Mind Institute and the Center for Neurogenetics at Weill Cornell Medicine. Symptoms of schizophrenia typically develop in adulthood, but postmortem studies of the brains of people with the disease found enlarged cavities called ventricles and differences in the cortical layers that likely occurred early in life.

New brain imaging technique suggests memories are stored in the connections between your neurons

Posted by in categories: biotech/medical, computing, neuroscience

All memory storage devices, from your brain to the RAM in your computer, store information by changing their physical qualities. Over 130 years ago, pioneering neuroscientist Santiago Ramón y Cajal first suggested that the brain stores information by rearranging the connections, or synapses, between neurons.

Since then, neuroscientists have attempted to understand the physical changes associated with memory formation. But visualizing and mapping synapses is challenging to do. For one, synapses are very small and tightly packed together. They’re roughly 10 billion times smaller than the smallest object a standard clinical MRI can visualize. Furthermore, there are approximately 1 billion synapses in the mouse brains researchers often use to study brain function, and they’re all the same opaque to translucent color as the tissue surrounding them.

Elon Musk’s brain-implant startup Neuralink may have misled regulators about Musk’s leadership role

Posted by in categories: computing, Elon Musk, government, law, neuroscience

Neuralink, the startup cofounded and run by Elon Musk that hopes to implant computer chips in people’s brains, may have misled federal securities regulators about the billionaire entrepreneur’s role at the company.

That’s according to government documents and Fortune interviews with securities lawyers and a half-dozen former employees of the company. The employees mostly spoke anonymously out of concern for violating nondisclosure agreements and possible retaliation from Musk.

The episode involves a 2018 letter in which an attorney representing Neuralink downplayed Musk’s leadership role at the company in a letter to the Securities and Exchange Commission. The attorney’s characterization contradicts former employees’ accounts, which depict Musk as very much in charge. Neuralink and the attorney involved in the filing did not respond to requests for comment. lawyer for Neuralink told the SEC that Musk had “no executive or management role” at the company. Former employees say that’s far from the truth.

The Omega Singularity: The Cosmological Projector of All Possible Timelines

Posted by in categories: computing, cosmology, mathematics, neuroscience, quantum physics, singularity

E verything is Code. Immersive [self-]simulacra. We all are waves on the surface of eternal ocean of pure, vibrant consciousness in motion, self-referential creative divine force expressing oneself in an exhaustible variety of forms and patterns throughout the multiverse of universes. “I am” the Alpha, Theta & Omega – the ultimate self-causation, self-reflection and self-manifestation instantiated by mathematical codes and projective fractal geometry.

In my new volume of The Cybernetic Theory of Mind series – The Omega Singularity: Universal Mind & The Fractal Multiverse – we discuss a number of perspectives on quantum cosmology, computational physics, theosophy and eschatology. How could dimensionality be transcended yet again? What is the fractal multiverse? Is our universe a “metaverse” in a universe up? What is the ultimate destiny of our universe? Why does it matter to us? What is the Omega Singularity?
