Blood-brain barrier building blocks forged from human stem cells
The blood-brain barrier -- the filter that governs what can and cannot come into contact with the mammalian brain -- is a marvel of nature. It effectively separates circulating blood from the fluid that bathes the brain, ...

Brain structure adapts to environmental change
Scientists have known for years that neurogenesis takes place throughout adulthood in the hippocampus of the mammalian brain. Now Columbia researchers have found that under stressful conditions, neural stem cells in the adult ...

'Unnatural' chemical allows researchers to watch protein action in brain cells
Researchers at the Salk Institute have been able to genetically incorporate "unnatural" amino acids, such as those emitting green fluorescence, into neural stem cells, which then differentiate into brain neurons with the ...

Neuroscientists propose revolutionary DNA-based approach to map wiring of whole brain
A team of neuroscientists has proposed a new and potentially revolutionary way of obtaining a neuronal connectivity map (the "connectome") of the whole brain of the mouse. The details are set forth in an essay published October ...

Neuroprosthesis gives rats the ability to 'touch' infrared light
Researchers have given rats the ability to "touch" infrared light, normally invisible to them, by fitting them with an infrared detector wired to microscopic electrodes implanted in the part of the mammalian brain that processes ...

How does the brain know what the tongue knows?
Each taste, from sweet to salty, is sensed by a unique set of neurons in the brains of mice, new research reveals. The findings demonstrate that neurons that respond to specific tastes are arranged discretely in what the ...

Data mining opens the door to predictive neuroscience
The discovery, using state-of-the-art informatics tools, increases the likelihood that it will be possible to predict much of the fundamental structure and function of the brain without having to measure every ...

Natural process activating brain's immune cells could point way to repairing damaged brain tissue
The brain's key "breeder" cells, it turns out, do more than that. They secrete substances that boost the numbers and strength of critical brain-based immune cells believed to play a vital role in brain health. This finding ...

GABA signaling prunes back copious 'provisional' synapses during neural circuit assembly
Quite early in its development, the mammalian brain has all the raw materials on hand to forge complex neural networks. But forming the connections that make these intricate networks so exquisitely functional is a process ...

A key gene for brain development
(Medical Xpress)—Neurobiologists at the Research institute of Molecular Pathology (IMP) in Vienna have discovered one of the key genes required to make a brain. Mutations in this gene, called TUBB5, cause ...

Researchers visualize memory formation for the first time in zebrafish
In our interaction with our environment we constantly refer to past experiences stored as memories to guide behavioral decisions. But how memories are formed, stored and then retrieved to assist decision-making ...

Search for epigenetic decoder leads scientists to Rett Syndrome
(Medical Xpress)—A few years ago, scientists discovered an unexpected layer of information woven into the genetic code – a nucleotide called 5-hydroxymethylcytosine, or 5hmC. Its meaning was unknown at the time, but a ...

Transmission routes of spreading protein particles
In diseases like Alzheimer's and Parkinson's endogenous proteins accumulate in the brain, eventually leading to the death of nerve cells. These deposits, which consist of abnormally formed proteins, are supposed to migrate ...
