Year 2021 Basically dmt may be a sorta chemical based computer that shapes our reality which could help understand why sometimes people have disorders of reality perception.
Do we see the world as it really is, or are we creating our own reality? We delve into the neuroscience behind the world that we experience.
Membrane-permeable psychedelics promote cortical neuron growth by activating intracellular serotonin 2A receptors.
Can we objectively tell how fast we are aging? With a good measure, scientists might be able to change our rate of aging to live longer and healthier lives. Researchers know that some people age faster than others and have been trying to concisely measure the internal physiological changes that lead to deteriorating health with age.
For years, researchers have been using clinical factors normally collected at physicals, like hypertension, cholesterol and weight, as indicators to predict aging. The idea was that these measures could determine whether someone is a fast or slow ager at any point in their life cycle. But more recently, researchers have theorized that there are other biological markers that reflect aging at the molecular and cellular level. This includes modifications to a person’s genetic material itself, or epigenetics.
The fungal pathogen that wipes out much of humanity in HBO’s latest series The Last of Us is real, but can the cordyceps fungus actually turn humans into zombies one day?
“It’s highly unlikely because these are organisms that have become really well adapted to infecting ants,” Rebecca Shapiro, assistant professor at University of Guelph’s department of molecular and cellular biology, told Craig Norris, host of CBC Kitchener-Waterloo’s The Morning Edition.
In the television series, the fungus infects the brain of humans and turns them into zombies. In real life, it can only infect ants and other insects in this manner.

Researchers have created a new optical illusion that makes your brain try to predict the future — namely, entering a dark tunnel.
Rs-fMRI is used to investigate human brain connectivity changes induced by prolonged microgravity in cosmonauts before and after spaceflight, with both persistent and reversible location specific changes in connectivity being observed.
The outer layer of the brain, known as the cortex, is made of different types of neurons. Neuroscience studies suggest that these different neuron types have distinct functions, yet for a long time this was difficult to ascertain, due to the inability to examine and manipulate them in the brains of living beings.
In recent years, genetic techniques opened new possibilities for studying cells and their functions. Using some of these techniques, researchers at Forschungszentrum Jülich, RWTH Aachen University, Cold Spring Harbor Laboratory and other institutes in the United States closely examined the functions of different pyramidal cells, which are commonly found in the human cortex.
Their findings, published in Nature Neuroscience, suggest that distinct types of pyramidal cells drive patterns of cortical activity associated with different brain functions. The team’s study builds on some of their previous works focusing on neuronal activity in the cortex.
A study suggests that the spinosaurs’ brains weren’t specialized for their semi-aquatic lifestyles.
Synchron’s BCI is inserted through the blood vessels, which Oxley calls the “natural highways” into the brain. Synchron’s stent, called the Stentrode, is fitted with tiny sensors and is delivered to the large vein that sits next to the motor cortex. The Stentrode is connected to an antenna that sits under the skin in the chest and collects raw brain data that it sends out of the body to external devices.
Peter Yoo, senior director of neuroscience at Synchron, said since the device is not inserted directly into the brain tissue, the quality of the brain signal isn’t perfect. But the brain doesn’t like being touched by foreign objects, Yoo said, and the less invasive nature of the procedure makes it more accessible.
“There’s roughly about 2,000 interventionalists who can perform these procedures,” Yoo told CNBC. “It’s a little bit more scalable, compared to, say, open-brain surgery or burr holes, which only neurosurgeons can perform.”
