New Microscope Helps Neuroscientists Ask New Questions

Last week, President Obama announced the Brain Research Through Advancing Innovative Neurotechnologies (BRAIN) Initiative, a 10-year project to map the human brain.  President Obama introduced BRAIN as a way of encouraging neuroscientists to develop new technologies to study how neurons within the brain communicate with each other. New technologies are essential to helping neuroscientists ask new questions about how the brain works.  This project is similar to two other major projects: The Human Brain Project (European Union), which is working on a computer simulation of the entire brain, and The Human Connectome Project (National Institutes of Health) which is using state of the art magnetic resonance imaging (MRI) to track projections all over the brain.Continue reading

Forming Memories, One Neuron at a Time

On Monday, Knowing Neurons highlighted a recent research article that described a new miniature microscope that was small enough to sit on a mouse’s head and light enough to allow it to move freely!  This technology represents a great advancement for the field of neuroscience in general and place cell research, specifically!  For the first time, researchers at Stanford are able to literally watch neurons turn on and off in the hippocampus of a mouse, while it explores an open arena (video), all in real time. This technology adds a new twist on a classic way of studying how the brain maps out the world around us.Continue reading
