Love it, indeed
Really good solution
Same as old one
The old one was better
This is a new option

MRI sensor allows neuroscientists to map neural activity with molecular precision

RATE THIS! +28
Posted in Science on 3rd May, 2014 11:54 PM by AlexMuller

Researchers have developed a technique that allows them to precisely track neural communication in the brain over time, with MRI.This is the first time anyone has been able to map neural signals with high precision over large brain regions in living animals.

 
A team used this molecular imaging approach, described in the May 1 online edition of Science, to study the neurotransmitter dopamine in a region called the ventral striatum, which is involved in motivation, reward, and reinforcement of behavior. In future studies, Jasanoff plans to combine dopamine imaging with functional MRI techniques that measure overall brain activity to gain a better understanding of how dopamine levels influence neural circuitry.
 
“We want to be able to relate dopamine signaling to other neural processes that are going on,” Jasanoff says. “We can look at different types of stimuli and try to understand what dopamine is doing in different brain regions and relate it to other measures of brain function.”
