    How to build a human brain

    In a white lab coat and blue latex gloves, Neda Vishlaghi peers through a light microscope at six milky-white blobs. Each is about the size of a couscous grain, bathed in the pale orange broth of a petri dish. With tweezers in one hand and surgical scissors in the other, she deftly snips one tiny clump in half.

    When growing human brains, sometimes you need to do some pruning.

    Learning takes brain acrobatics

    Peer inside the brain of someone learning. You might be lucky enough to spy a synapse pop into existence. That physical bridge between two nerve cells seals new knowledge into the brain. As new information arrives, synapses form and strengthen, while others weaken, making way for new connections.

    You might see more subtle changes, too, like fluctuations in the levels of signaling...

    Infant brains have powerful reactions to fear

    SAN DIEGO — Babies as young as 5 months old possess networks of brain cell activity that react to facial emotions, especially fear, a new study finds.

    “Networks for recognizing facial expressions are in place shortly after birth,” Catherine Stamoulis of Harvard Medical School said November 13 during a news conference at the annual meeting of the Society for Neuroscience. “This work … is...

    Nerve cell migration after birth may explain infant brain’s flexibility

    Baby humans’ brain cells take awhile to get situated after birth, it turns out. A large group of young nerve cells moves into the frontal lobe during infants’ first few months of life, scientists report in the Oct. 7 Science. The mass migration might help explain how human babies’ brains remain so malleable for a window of time after birth.  

    Most of the brain’s nerve cells, or neurons,...
