NOTE FROM TED: Please do not look to this talk for mental health advice. This talk represents the speaker’s personal views and interpretation of psychedelics and mental health, which remains an emerging field of study. We’ve flagged this talk because it falls outside the content guidelines TED gives TEDx organizers. TEDx events are independently organized by volunteers.

Psychedelics as medicine to treat mental health disease has had a recent resurgence of attention and dedicated research, with encouraging results. Could this class of drugs serve as a paradigm shift in the way mindfulness therapy and mental health is approached? Compounds like LSD, DMT, psilocybin, and MDMA are investigated as treatments for states of anxiety, depression, PTSD, and addiction. Listeners are challenged to question their preconceived notions and judgements as it pertains to this group of restricted therapeutics in the psychedelic class. Burton J. Tabaac, MD FAHA

A group of neuroscientists developed a test to detect a novel marker of Alzheimer’s.

Alzheimer’s disease is a disease that attacks the brain, causing a decline in mental ability that worsens over time. It is the most common form of dementia and accounts for 60 to 80 percent of dementia cases. There is no current cure for Alzheimer’s disease, but there are medications that can help ease the symptoms.

New insights into the opposing actions of serotonin-producing nerve fibers in mice could lead to drugs for treating addiction and major depression.

Scientists in Japan have identified a nerve pathway involved in the processing of rewarding and distressing stimuli and situations in mice.

The new pathway, originating in a bundle of brain stem nerve fibers called the median raphe nucleus, acts in opposition to a previously identified reward/aversion pathway that originates in the nearby dorsal raphe nucleus. The findings, published by scientists at Hokkaido University and Kyoto University with their colleagues in the journal Nature Communications, could have implications for developing drug treatments for various mental disorders, including addiction and major depression.

New research in Biological Psychiatry offers the first direct evidence of diminished 5-HT release cements “serotonin hypothesis.”

Researchers have postulated since the 1960s that major depression stems from disruptions in the serotonin neurotransmitter system. However, the evidence for that idea, though plentiful, was indirect. In fact, a recent comprehensive analysis of existing studies concluded that there was not strong evidence to support the “serotonin hypothesis.” In its wake, some in the field have called for a reexamination of the hypothesis. Not so fast, says a new study that provides direct evidence of disrupted serotonin release in the brains of individuals with depression.

The study was published recently in the journal Biological Psychiatry.

As a general rule, if you want sight, you need light. You’re only reading this right now thanks to the light from your screen being beamed onto your retinas, converted into electrical signals, and sent up the optic nerve for your brain to interpret as a bunch of words and images.

But what if you could see things without all that rigamarole? It might sound impossible – perhaps even counter to the very definition of sight – but thanks to the bizarre world of quantum mechanics, it’s actually perfectly possible.

“Since the inception of quantum mechanics, the quest to understand measurements has been a rich source of intellectual fascination,” notes a new paper published this month.

Brain computer interface. People even so called experts are so narrow they have lobotimized their vision.

A team led by UCL and UCLH researchers have mapped the parts of the brain that support our ability to solve problems without prior experience—otherwise known as fluid intelligence.

Fluid intelligence is arguably the defining feature of human cognition. It predicts educational and professional success, social mobility, health, and longevity. It also correlates with many cognitive abilities such as memory.

Fluid intelligence is thought to be a key feature involved in “active thinking”—a set of complex mental processes such as those involved in abstraction, judgment, attention, strategy generation and inhibition. These skills can all be used in everyday activities—from organizing a dinner party to filling out a tax return.

Although genetically modified foods still get a bit of a bad rap, there are actually many good reasons why modifying an organism’s genetics may be worthwhile. For example, many breeds of genetically modified foods have made them more resistant to disease.

It’s also possible to modify foods to make them more nutritious. Take, for example, golden rice. This grain was engineered to have higher levels of vitamin A in order to tackle deficiencies of this nutrient in impoverished countries.

A purple tomato, created using genetic modification, may be available to buy in the U.S. as soon as 2023.

South Korea has reported its first death due to Naegleria fowleri or ‘Brain-eating amoeba.’ The amoeba enters through the nose and attacks the brain, causing meningitis. Should you be scared?
