Mind over matter: Scientists unlock regeneration mechanism for brain injury

Basically this is one of the cure all options for thousands of brain disorders.


Researchers in Portugal have discovered a new collaborative mechanism that unveils how neural stem cells sense injury and communicate for tissue repair, moving science closer to boosting neuron regeneration after brain damage.

Stroke and traumatic brain injury can permanently damage neurons and, depending on injury site, patients may experience long-term impairments of critical motor or cognitive functions. For this reason, the brain has a reserve of special cells—known as neural stem cells—that can partially activate after tissue damage.

However, though many stem cells begin the process of regeneration, complete activation only happens in a few, meaning only a small number of fresh neurons are created. Fewer still survive to re-populate the damaged site. Instead, the area is typically filled by glia, a common non-neural support cell, which acts as the “glue” of the nervous system.

Clinical Trial Examines Synthetic Psilocybin as a Treatment for Severe Depression

Individuals suffering from severe depression may find relief from just a single dose of a synthetic version of psilocybin, or “magic mushrooms,” according to a new study published this week.

The findings, which were published Wednesday by The New England Journal of Medicine, come from a double-blind trial involving 233 “randomly assigned adults with treatment-resistant depression [who received] a single dose of a proprietary, synthetic formulation of psilocybin at a dose of 25 mg, 10 mg, or 1 mg (control), along with psychological support.”

“In this phase 2 trial involving participants with treatment-resistant depression, psilocybin at a single dose of 25 mg, but not 10 mg, reduced depression scores significantly more than a 1-mg dose over a period of 3 weeks but was associated with adverse effects,” the authors wrote in their conclusions, adding that “larger and longer trials, including comparison with existing treatments, are required to determine the efficacy and safety of psilocybin for this disorder.”

Rare success for Alzheimer’s research unlocks hope for future therapies

CHICAGO, Nov 29 (Reuters) — The first big breakthrough in 30 years of Alzheimer’s research is providing momentum for clinical trials of “cocktail” treatments targeting the two hallmark proteins associated with the mind-robbing disease, according to interviews with researchers and pharmaceutical executives.

Scientists hail major breakthrough in fight against Alzheimer’s as drug proven to slow disease

‘This is the first drug that provides a real treatment option,’ says leading researcher Scientists are hailing a historic step in the fight against Alzheimer’s, after a drug was proven to slow the disease in long-awaited clinical trials. The breakthrough comes after decades of failed attempts to find a way to do so, and has prompted hope among experts that it could eventually pave the way for treatments which could ultimately lead to a cure.

TALK ABSTRACT
Life was solving problems in metabolic, genetic, physiological, and anatomical spaces long before brains and nervous systems appeared. In this talk, I will describe remarkable capabilities of cell groups as they create, repair, and remodel complex anatomies. Anatomical homeostasis reveals that groups of cells are collective intelligences; their cognitive medium is the same as that of the human mind: electrical signals propagating in cell networks. I will explain non-neural bioelectricity and the tools we use to track the basal cognition of cells and tissues and control their function for applications in regenerative medicine. I will conclude with a discussion of our framework based on evolutionary scaling of intelligence by pivoting conserved mechanisms that allow agents, whether designed or evolved, to navigate complex problem spaces.
