Can scientists read your mind and figure out what you’re thinking just by looking at your brain? Well, sort of.

In this episode of The Social Brain with Taylor Guthrie (@The Cellular Republic) and I (@Sense of Mind) talk about a fascinating new area of cognitive neuroscience, called “brain decoding” as well as its counterpart, “brain encoding,” and related topics. It all centers on the question posed above and the future applications, some of which are scary while others are inspiring.

Tiny single-celled critters obviously don’t have room for a brain to tell them how to move in complex ways, so to get about, they usually roll, slither or swim.

But microscopic pond dwellers called Euplotes eurystomus have mastered a way to walk brainlessly – scurrying about like insects, with their 14 little appendages.

The mechanisms underlying decision-making have been a long-standing focus of neuroscience research. But now, researchers from Japan have found new information about how the reward system in the brain processes risky decisions.

In a study recently published in Nature Communications, researchers from the University of Tsukuba have revealed that individual neurons in the neural circuit that processes reward information fire in accordance with a well-established theory used to describe the decision-making process.

First proposed in the 1970s, prospect theory is a highly influential concept used to describe how people and animals make choices. Although this theory has been supported by thousands of studies, limitations in the temporal and spatial resolution of human neuroimaging techniques have prevented researchers from determining whether the activity of individual neurons follows this pattern, something that the researchers at the University of Tsukuba aimed to address.

Summary: Proteins associated with motor neuron disease, or ALS are present in the gut many years before disease pathologies can be found in the brain. A stool sample or gut biopsy could help identify the presence of MND-associated proteins years before symptoms appear.

The same proteins thought to contribute to motor neuron disease can be found in the gut many years before any brain symptoms occur, a new study by the University of Aberdeen has found.

“This data set—and the opportunities it creates—are … arguably one of the most important things to have happened in neurobiology recently,” says Rachel Wilson, a neurobiologist at Harvard University who was not involved in the new work. “Anyone in the world who is interested can download the data set and determine whether any two neurons … talk to each other.”

This is not a knock on caffeine by any means. There’s a reason people have been consuming it for thousands of years. It works by blocking the neurotransmitters in the brain that produce drowsiness. This keeps your neurons firing at full speed, which makes you feel awake. And studies show it is very effective at boosting mood. But what if you could do more for your brain than simply tricking it into being awake? What if you could give your brain nutrients that help it work better all the time? Well, with a well-designed nootropics supplement, you can.

Nootropics are often marketed as “smart drugs,” which gives the impression that they’re going to boost your IQ and turn you into a rocket scientist or brain surgeon. But that is not actually the case. Nootropics are simply chemical compounds that help create the biological conditions necessary for optimal brain function. They include things like amino acids, vitamins, minerals, nutrients, and even stimulants such as caffeine. Some of these compounds serve as fuel for cognition. Others modulate various processes involved in neurotransmission.

Short cycles of a low-calorie diet that mimics fasting appeared to lower inflammation and delay cognitive decline in 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.

There could soon be a treatment for neuropsychiatric disorders that cause social deficits—such as autism spectrum disorder and schizophrenia. If the treatment.

Self-organizing lumps of human brain tissue grown in the laboratory have been successfully transplanted into the nervous systems of newborn rats in a step towards finding new ways to treat neuropsychiatric disorders.

The 3D organoids, developed from stem cells to resemble a simplified model of the human cortex, connected and integrated with the surrounding tissue in each rat’s cortex to form a functional part of the rodent’s own brain, displaying activity related to sensory perception.

This, according to a team of researchers led by neuroscientist Sergiu Pașca of Stanford University, overcomes the limitations of dish-grown organoids, and gives us a new platform for modeling human brain development and disease in a living system.
