"When we activated an individual nerve cell
, it caused a perception of pain, so we conclude that these nerve cells
are connected to pain centres in the brain," said Saad Nagi.
It was obtained from pluripotent stem cells through a fast forward programming method and provides highly standardized conditions for investigating nerve cell
In growing brains, billions of nerve cells
must make trillions of precise connections.
When newborn babies open their eyes for the first time, they already possess nerve cells
specialized in particular stimuli in the visual cortex of their brains -- but these nerve cells
are not systematically linked with each other.
The nerve cells
that transmit the signal to the brain often get damaged.
One type of nerve cell
group responds at the moment when the monkeys realize that their answer was correct, while the other type responds when their answer was not correct.
"Plaques are little dead zones between the nerve cells
," explains Lee Eiden of the National Institute of Mental Health's Laboratory of Cellular and Molecular Regulation.
* Nonsteroidal anti-inflammatory drugs (NSAIDs) may aid in preventing or delaying the onset of Alzheimer's by protecting nerve cells
in the brain from inflammation that may contribute to nerve cell
This unhealthy diet also kicked nerve cell
production into high gear.
NIEHS grantee Bruce Ames and colleagues at the Children's Hospital Oakland Research Institute in Oakland, California, investigated the effect of a decline in heme on nerve cell
"We learned there are 10 different genes in the nerve cell
's DNA that produce different sodium channels.
