Over the years, this stress may be more than the neuron can handle, leading to the gradual deterioration of the sprouted fibers and, eventually, of the neuron itself.
In addition, Techniques like Positron Emission Tomography (PET), Single Photon Emission Computed Tomography (SPECT), and Magnetic Resonance Imaging (MRI) are going to unravel the mystery of the neuron jungle.
In an attempt to stave off Arya's decline until something better came along, her parents and doctors decided to try hydroxyurea, an old cancer drug that had been shown to boost levels of the neuron-nourishing protein somewhat in preliminary lab tests.
"They are not much larger than the dimensions of a neuron in the brain, " said materials scientist John Rogers at the University of Illinois, who helped develop them.

In the brain, the signals travelling through the synapses rely on action potential, which is the electrical energy created by the difference in concentrations of charged atoms (ions) on the inside and outside of neuron, which move back and forth through ion channels.

In turn, this leads to the formation of the characteristic protein "tangles" found in the brains of people with Alzheimer's, the researchers told Neuron.
Iacobani explained that when one tells a purposeful story in the room, face to face, they evoke the mirror neuron system of their listener to feel what they are feeling in their tell and thus mirror the same intentions.
Boyden and Forest, working with Forest's graduate student Suhasa Kodandaramaiah, developed a robotic system to record activity of a single neuron in the living brain using a tiny glass tube.
Sweden, Greece, Switzerland, Spain, Italy and France are working on a joint project through state-owned aeronautical companies and are in the final stages of developing an advanced armed drone prototype called the Dassault nEURon, from which the France plans to derive armed drones for its air force.
In the human brain, a synapse is the structure which enables a neuron to send information to other parts of the brain.

The jet-lagged hamsters showed a drastic drop in neuron production in the hippocampus area of the brain, which closely contributes to memory processing and learning.
If television produced the global village, the Internet produces the global psyche: everyone keyed in like a neuron, so that to the eyes of a watching Martian we are really part of a single planetary brain.
One of their tools is a laser that can activate a neuron in the animal's brain.
One of the features of a brain with Alzheimer's disease is the loss of synapses, which are junctions between two neurons or between a neuron and a muscle.
CNN: Nutritional drink, imaging show promise for Alzheimer's
Depending on just how researchers tailor the virus that carries the light-sensitive protein, they now can target almost any type of neuron they want to study.
