“Dr. Belliveau was a 30-year-old graduate student at the Martinos Center when he hatched a scheme to “see” the neural trace of brain activity. …

Dr. Belliveau tried a different approach. He had developed a technique to track blood flow, called dynamic susceptibility contrast, using an M.R.I. scanner that took split-second images, faster than was usual at the time. This would become a standard technique for assessing blood perfusion in stroke patients and others, but Dr. Belliveau thought he would try it to spy on a normal brain in the act of thinking or perceiving.
…
“He went out to RadioShack and bought a strobe light, like you’d see in a disco,” said Dr. Bruce Rosen, director of the Martinos Center and one of Dr. Belliveau’s advisers at the time. “He thought the strobe would help image the visual areas of the brain, where there was a lot of interest.”

The #Brain #Somatic Mosaicism Network
http://science.ScienceMag.org/content/356/6336/eaal1641 Long lifespan of neurons accentuates impact of individual somatic mutations

QT:{{”
Neuropsychiatric disorders have a complex genetic architecture. Human genetic population-based studies have identified numerous heritable sequence and structural genomic variants associated with
susceptibility to neuropsychiatric disease. However, these germline variants do not fully account for disease risk. During brain development, progenitor cells undergo billions of cell divisions to generate the ~80 billion neurons in the brain. The failure to accurately repair DNA damage arising during replication,
transcription, and cellular metabolism amid this dramatic cellular expansion can lead to somatic mutations. Somatic mutations that alter subsets of neuronal transcriptomes and proteomes can, in turn, affect cell proliferation and survival and lead to neurodevelopmental disorders. The long life span of individual neurons and the direct relationship between neural circuits and behavior suggest that somatic mutations in small populations of neurons can significantly affect individual neurodevelopment. The Brain Somatic Mosaicism Network has been founded to study somatic mosaicism both in neurotypical human brains and in the context of complex neuropsychiatric disorders.” “}}
