The generation of new nerve cells in the brain is regulated by a peptide known as C3a, which directly affects the stem cells' maturation into nerve cells and is also important for the migration of new nerve cells through the brain tissue, reveals new research from the Sahlgrenska Academy published in the journal Stem Cells. (2009-11-23)

Stimulating brain cells with light
Introducing a light-sensitive protein in transgenic nerve cells... transplanting nerve cells into the brains of laboratory animals... inserting an optic fiber in the brain and using it to light up the nerve cells and stimulate them into releasing more dopamine to combat Parkinson's disease...

(2014-05-27)

New study: Malaria tricks the brain's defence system
Malaria is one of the most common causes of death in children in Africa. When the parasite builds up in the blood vessels of the brain, it develops into one of the most dangerous forms of the disease, cerebral malaria. Though it wasn't certain if the parasite was able to penetrate the brain tissue, now researchers from the University of Copenhagen have found parasites can do that and have mapped the mechanism they utilise. (2021-01-26)

Brain cells divide the work to recognize bodies
Specific regions of the brain are specialized in recognizing bodies of animals and human beings. By measuring the electrical activity per cell, scientists from KU Leuven, Belgium, and the University of Glasgow have shown that the individual brain cells in these areas do different things. Their response to specific contours or body shapes is very selective. (2016-04-28)

Dying of excitement
For neurons, overexcitement is deadly. To avoid this, brain cells must sop up unneeded neurotransmitters from the synapse through membrane-bound transporters. If these transporters fail, neurons and other brain cells get excited to death -- a phenomenon that may contribute to brain damage during stroke and Alzheimer's disease. (2006-03-06)
