Selective memory
Using genetic engineering and chemical manipulation, scientists erased the memory of a stressful experience from a mouse’s brain.

New insights on new neurons
Neurogenesis works differently in two parts of the brain. New neurons are necessary for making memories and keep the olfactory bulb’s structure but aren’t needed for smelling, study in mice shows.

Neuron Killers
Misfolded, clumping proteins evade conviction, but they remain prime suspects in neurodegenerative diseases.

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.

Restoring Recall: Memories may form and reform, with sleep
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.
