US scientists create most comprehensive circuit diagram of mammalian brain | The 3D map of a cubic millimetre of mouse brain reveals half a billion synapses and 5.4km of neuronal wiring


The 3D map of a cubic millimetre of mouse brain reveals half a billion synapses and 5.4km of neuronal wiring

The MICrONS project sought not only to map the structure of neurons, but also investigated the electrical signalling between then, showing how they communicate and providing a better picture of the hidden conversations in the brain. Scientists at Baylor College of Medicine in Texas began by using specialised microscopes to record the brain activity from the target region as the animal watched various movies and YouTube clips. “Inside that tiny speck is an entire architecture like an exquisite forest,” said Dr Clay Reid, senior investigator and a neurobiologist at the Allen Institute.
