    Breaking the Barrier

    A technique combining ultrasound pulses with microbubbles may help scientists move therapeutic drugs across the brain’s protective divide.

  2. Neuroscience

    Highly wired

    Men’s brain tissue shows higher density of neuron connections than similar tissue from women.

  3. Neuroscience

    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.

  4. Health & Medicine

    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.
