New Research Shows How Ketamine Acts As “Switch” in the Brain

According to a new study by researchers at Penn Medicine, ketamine, which is well-known as an anesthetic and is becoming increasingly popular as an antidepressant, dramatically reorganizes activity in the brain, almost as if a switch were turned on. The study, published in Nature Neuroscience, found that after administering ketamine, there were drastic changes in the patterns of neuronal activity in the cerebral cortex of animal models. Neurons that were usually active were silenced, while others that were usually inactive suddenly became active.

Precision Neuroscience is making brain implants safer, smarter and reversible

In order to understand what’s going on in the brain, sometimes a EEG or MRI from outside it just isn’t enough — you need to really get in there. Implanted electrodes have been used for this purpose for a long time, and arrays of them in formation are used to collect information from multiple points within the cortex at the same time.

Focused ultrasound technique leads to release of neurodegenerative disorders biomarkers

Several progressive neurodegenerative disorders, including Alzheimer's disease, are defined by having tau proteins in the brain. Researchers are seeking to identify the mechanisms behind these tau proteins to develop treatments, however, their efforts to detect biomarkers in blood has been hampered by the protective blood-brain barrier. At Washington University in...

Tuning into brainwave rhythms speeds up learning in adults, study finds

Scientists have shown for the first time that briefly tuning into a person's individual brainwave cycle before they perform a learning task dramatically boosts the speed at which cognitive skills improve. Calibrating rates of information delivery to match the natural tempo of our brains increases our capacity to absorb and...

Harnessing the brain's ability to self-heal

Powerful electromagnets could be the answer to a new wave of treatments for depression, schizophrenia, Alzheimer's and more. About 200 years ago, a railway foreman named Phineas Gage had a very bad day. While clearing up large rocks with the aid of explosives, misfortune struck and a 6kg metal rod, known as a tamping iron, shot up at Phineas and went straight through his head.

Pregnancy and Cannabis Are a Bad Recipe

Cannabis use is common during pregnancy, especially in the first trimester. THC concentrations in a fetus are one-third of the concentration found in the mother's blood. THC interferes with a fetus's natural cannabinoid chemistry guiding axon growth necessary for proper brain development. Adverse consequences for cognition and attention throughout childhood...

ChatGPT Resembles a Slice of the Human Brain

Language is commonly understood to be the “stuff” of thought. People “talk it out” and “speak their mind,” follow “trains of thought” or “streams of consciousness.” Some of the pinnacles of human creation—music, geometry, computer programming—are framed as metaphorical languages. The underlying assumption is that the brain processes the world and our experience of it through a progression of words. And this supposed link between language and thinking is a large part of what makes ChatGPT and similar programs so uncanny: The ability of AI to answer any prompt with human-sounding language can suggest that the machine has some sort...
