This video shows rats choosing sequentially from four distinct trajectories in a maze while we record neural activity from hippocampus and cingulate cortex. Analyses of such neural activity led us to ...
Mengingitis Breaks the Blood-Brain Barrier. But how?
Mengingitis Breaks the Blood-Brain Barrier. But how? - Stefano Marullo and colleagues explain how meningococcus hijacks a beta-arrestin signaling cascade to open gaps and slip right through intercellu...
