'Bioprinting' living brain cell networks in the lab

Monash University Engineering researchers have successfully used "bioinks" containing living nerve cells (neurons) to print 3D nerve networks that can grow in the laboratory and transmit and respond to nerve signals. The ...

Research identifies gene 'fingerprint' for brain aging

Most of us who've reached middle age have noticed a slowing in memory and cognition, but scientists don't have a clear picture of the molecular changes that take place in the brain to cause it.

Lessons from an experimental brain phantom

Researchers at the National Institute of Standards and Technology (NIST) and colleagues have developed a novel, anatomically accurate reference model of the human brain, entirely made from soft organic materials, for use ...

White matter

White matter is one of the two components of the central nervous system and consists mostly of myelinated axons. White matter tissue of the freshly cut brain appears pinkish white to the naked eye because of myelin is composed largely of lipid and a few percent of capillaries. Its white color is due to its usual preservation in formaldehyde. A 20 year-old male has around 176,000 km of myelinated axons in his brain.

The other main component of the brain is grey matter (actually pinkish tan due to blood capillaries). A third colored component found in the brain that appears darker due to higher levels of melanin in dopaminergic neurons than its nearby areas is the substantia nigra.
