Whether you break an egg or break into dance, our brain handles the word “break” the same.
‘Clock time’ is not the same as ‘mind time’.
They’re so cute and fuzzy, too <3.
The infamous three F’s.
Fortunately, they’re hot on the heels of the mechanisms that allow them to affect brain cells.
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
