    Astrocytes are rising stars

    Astrocytes, brain cells previously thought to be support cells for neurons, regulate blood flow in the brain and may aid neuron signaling. The regulation of blood flow makes visualizing brain activity with fMRI possible.

    Two new studies indicate that memories, at least for skills learned in a laboratory, undergo a process of storage and restorage that depends critically on sleep.
