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 ...

How the brain folds to fit
During fetal development of the mammalian brain, the cerebral cortex undergoes a marked expansion in surface area in some species, which is accommodated by folding of the tissue in species with most expanded ...

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 ...

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 ...

Response and recovery in the brain may predict well-being
(Medical Xpress)—It has long been known that the part of the brain called the amygdala is responsible for recognition of a threat and knowing whether to fight or flee from the danger.

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 ...

Rats' stroke-induced seizures stopped with pulse of light
(Medical Xpress)—Stanford University School of Medicine scientists have shown that a structure deep within the brain is a crucial component of recurring seizures that can arise as a delayed consequence of a cerebral stroke. ...

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 ...

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 ...

Research identifies protein that regulates key 'fate' decision in cortical progenitor cells
Researchers at Cold Spring Harbor Laboratory (CSHL) have solved an important piece of one of neuroscience's outstanding puzzles: how progenitor cells in the developing mammalian brain reproduce themselves while also giving ...

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, ...

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 ...
