The team believed that ketamine affected a small part of the brain, called the lateral habenula, also known as the “anti–reward center.”
Maybe other drugs have similar effects.
We’re learning about learning!
The brain’s complex web just got a lot more tangled.
Keep it tidy, neurons.
Broken axons are like a broken router — no connection.
Sleep is very important for the brain. Here’s what happens during the most active phase of sleep.
It’s pretty scary that they can do it to be honest.
One step closer to understanding memory.
A new study offers insight into how neurons work together to make us remember stuff.
Researchers at the Washington University School of Medicine, St. Louis and University of Illinois at Urbana-Champaign have developed implantable devices that can activate — and in theory, block too — pain signals traveling from the body through the spinal cord before they reach the brain.
Capitalizing a more than a decade’s worth of neuroscience and computer science research, an international team of 82 researchers from institutions around the world report one the most detailed digital reconstruction of a mammalian brain. The researchers simulated 30,000 neurons and almost 40 million synapses, part of a rat’s brain measuring less than a third of a cubic millimeter. It’s a small step that might one day help simulate the whole brain, not just of rats, but also of humans – the ultimate goal of the Human Brain Project (HBP), an ambitious project which the European Commission prioritized and awarded $1 billion in funding.
By ‘tickling’ select membrane channels you can effectively control neurons, by activating or deactivating cells. You can do this using electrical currents, like we see very well illustrated in brain-computer interfaces; light (the field of optogenetics); and sound (sonogenetics). Yes, sound. This was only recently demonstrated by researchers at Salk’s Molecular Neurobiology Laboratory who used ultrasounds to control neurons in the nematode Caenorhabditis elegans.
Most medical research looking to identify the mechanisms of a disease or test treatments rely on animal models. While very useful, mice for instance (a favorite lab pet for researchers) do not have nearly the same brain structure or genes as humans. Even if some genes and proteins scientists target are the same both in mice and humans, it will
Scientists have discovered an atypical gene that is thought to be crucial for the generation of new neurons in the brain, a process called neurogenesis. The discovery and further study of the gene might help scientists better understand how neurodegenerative diseases such as Alzheimer’s affect the brain and, in term, how to address them. New neurons are born through a
A long-time assumption in the medical world is that mature, differentiated neurons do not divide and that they’re formed during the embryonic development stage. This does not necessarily mean, however, that all neurons are grown during this stage only and that they do not form during adulthood as well. Proving that neurons can form during adulthood is a difficult task however
There are a number of factors that lead to obesity, the most obvious of which is of course eating too much, without burning the excess fat by exercising. Fact is, there are some people in the world who no matter how much they’d eat, they never seem to be satisfied, constantly consumed by a sense of hunger and a voracious
I recently came across a very interesting piece in the NY Post which cites a study that shows that while it was well known that a difference in size between male and female brains exists, there is now evidence that there are significant differences in the size of certain structural parts of the brain, according to gender. As such, researchers
A group of scientists from the University of Texas Southwestern Medical Center discovered a new chemical compound that helps newborn neurons grow into mature brain cells called P7C3. This particular chemical makes new neurons grow in the part of the brain that is integral to learning and memory! This means the research, funded in part by the National Institutes of
We’ve all endured some kind of physical pain, more or less intense. When you hit your finger while hammering, for example, the pain is really intense, but passes away (at least mostly) in just a few moments. So scientists were trying to find out why is it that some intense pains pass so quickly and why some have to be
