What Ketamine Does to the Human Brain - The Atlantic

Frequent, heavy recreational use—say, several times a week—has been linked to cognitive effects that last beyond the high, including impaired memory, delusional thinking, superstitious beliefs, and a sense of specialness and importance. You can see why people might wonder about ketamine use from a man who is trying to usher in multi-planetary human life, who has barged into global politics and is attempting to reengineer the U.S. government. With Musk's new political power, his cognitive and psychological health is of concern not only to shareholders of his companies' stocks but to all Americans. His late-night posts on X, mass emails to federal employees, and non sequiturs uttered on television have prompted even more questions about his drug use...

Psychedelics open your brain. You might not like what falls in. - The Atlantic

At their best, psychedelics and other neuroplasticity-enhancing drugs can do some wonderful things, such as speed up the treatment of depression, quell anxiety in terminally ill patients, and alleviate the worst symptoms of PTSD. That's enough reason to research their uses and let patients know psychedelics are an option for psychiatric treatment when the evidence supports it. But limitless drug-induced self-enhancement is simply an illusion...

What Donald Trump, Vladimir Putin and Viktor Orbán Understand About Your Brain - POLITICO

In order to hack into the minds of the public, people need to feel fear or uncertainty. That could be caused by economic instability or pre-existing cultural prejudices, but the emotional basis is fear. The brain is designed to respond to fear in various ways, with its own in-built defense mechanisms which produce chemicals in the response pattern, such as cortisol and adrenaline. These chemical responses, which zip straight past our logical brains to our fight-or-flight reactions, are also activated by forms of language that instill fear, either directly (as in a vocal threat) or, more insidiously, by twisted facts which allay fears through lies and deceptive statements…

Racism takes its toll on brain and body | EurekAlert!

"This new study sheds light on the broad impact of exposure to racism on emotions, brain activity, inflammatory markers in the blood, and the composition of the gut microbiome. We would not be surprised to learn that exposure to racism affects how we feel and how we cope with this exposure and other life stresses. However, this study goes further to highlight brain patterns of response to racism and other factors that affect physical health, including the types of bacteria growing in the gut and the levels of inflammation in the body. These are factors that influence many disease processes in the body."…

A neuroscientist explains how religious fundamentalism hijacks the brain - Raw Story - Celebrating 17 Years of Independent Journalism

… We also know that in the United States, Christian fundamentalism is linked to science denial. Since science is nothing more than a method of determining truth using empirical measurement and hypothesis testing, denial of science equates to the denial of objective truth and tangible evidence. In other words, the denial of reality. Not only does fundamentalism promote delusional thinking, it also discourages followers from exposing themselves to any different ideas, which acts to protect the delusions that are essential to the ideology…

Half of all homeless people may have had traumatic brain injury

Half of all homeless people may have suffered a traumatic brain injury at some point in their life, according to new research – which experts say could be either a consequence or even the cause of their homelessness. Traumatic brain injury is sudden damage caused by a blow or jolt to the head, which can be caused by a motor accident, a fall or an assault. Sometimes it can cause long-term damage to the brain, leading to neurological and psychiatric disorders....
