MIT discovers the location of memories: Individual neurons. By triggering a single neuron, researchers were able to force a subject [a mouse] to recall a specific memory. By removing this neuron, the subject would lose that memory.
Article :: More than 100 years ago, Golgi staining on nerve cells opened the gates to modern neuroscience. Scientists recently developed the Technicolor version of Golgi staining, Brainbow, allowing more detailed reconstructions of brain circuits.
The Cell: An Image Library. Confocal image of pastel neurons in the hippocampus of a "Brainbow" mouse brain, with each neuron expressing a distinct color. In Brainbow mice, neurons randomly choose combinations of red, yellow and cyan fluorescent proteins.
