Learning from Disorder: The Paradox of Information in the Brain

In Dante’s Inferno, the fifth circle of Hell is a place where the wrathful fight each other for eternity.  Similarly, I often consider YouTube comments to be an extracanonical circle of Hell where the trolls fight each other for eternity.  You might, then, imagine my surprise when I found many thoughtful comments expressing wonder and intrigue on a YouTube video of brain activity in a zebrafish.  Continue reading

Surfing Brainwaves with EEG: A Classic Tool for Recording Temporal Brain Dynamics

Pictures are powerful tools for illustrating quantitative data and capturing public interest.  Each year, NASA releases many beautiful images of Martian dunes and distant nebulae which help win public funding.  Likewise, when it comes to grabbing headlines and commanding public attention, noninvasive studies of functional brain activity often do best when they beautifully illustrate said activity as colorful pixels dancing on the convoluted surface of the cerebral cortex.Continue reading

Mapping the Information Highway in the Brain Knowing Neurons

Mapping the Information Highway in the Brain

It’s hard to imagine life without Google Maps nowadays.  We use the interactive map daily to find out how to get from point A to point B.  Wouldn’t it be great if there were an online map to guide neuroscientists to study the brain?  In the newest issue of Cell, researchers from University of Southern California published a project mapping the neural networks of the mouse cortex, and they call it the Mouse Connectome Project (MCP).Continue reading

Imaging the Brain with Sculpted Light

Perhaps the biggest goal in neuroscience is to understand how individual neurons interact with each other in both space and time.  The more detailed our understanding of complex neural networks is, the more we can understand how an organism’s nervous system processes information to generate behavior.  To achieve this goal, neuroscience research has focused on obtaining detailed anatomical wiring maps, such as those produced by the Human Connectome ProjectContinue reading
