Of 100 billion nerve cells in the human brain, how many form after birth For years, the official answer was "zero". Scientists thought people were born with all the neurons they’d ever have. But from 1980s, biologists overturned that doctrine, finding a reservoir of stem cells that becam...
The human brain’s most significant memory system isvisuospatial memory[3](location + visual elements).Music[4],memory[5],environmental simulation in the brain[6],time[7], andlanguage[8]are all spatial arrangements of information in the brain. We understand navigation and locations very well, ...
And similarly, the more we learn about the human brain, the more avenues are likely to open up for neuromorphic computing researchers. For example, glial cells -- the brain's support cells -- don't figure highly in most neuromorphic designs, but as more inform...

The evidence that the brain needs amino acids is, by comparison, indirect. An important indication of how vital amino acids are to the brain is the mental retardation which is caused by many inborn errors which disturb the metabolism of amino acids in the body as a whole, which have been ...
You often hear people comparing the human brain and the electronic computer and, on the face of it, they do have things in common.A typical brain contains something like 100 billion minuscule cells called neurons (no-one knows exactly how many there are and estimates go from about 50 ...
Many different types of cells work together in the brain. In humans, nerve cells (neurons) make up less than half of the cells. The rest are called "glia." The most common glial cells are astrocytes. They supply the neurons with nutrients, form part of the blood-brain barrier, regulate...
A conceptual obstacle for understanding immune-to-brain signaling is the issue of the blood–brain barrier (BBB). In the last 30 years, several pathways have been investigated to address the question of how peripheral immune signals are transmitted into the brain. These pathways can be categorized...
Many animal studies have shown that neuronal and neural stem cell transplantation strategies can improve functional recovery after different types of SCI, providing a new way for the successful treatment of human SCI in the future and bringing hope to patients with SCI5-8. Neural stem cells are ...
“In the human brains, the virus-injected mice, and the cultured cells, the influenza virus tended to accumulate in endothelial cells,” explains lead author of the study Shihoko Kimura-Ohba. “These cells create a barrier between the blood and the brain, and are important for protecting the...
