Ed Boyden: A light switch for neurons
Ed Boyden TED Ed Boyden shows how, by inserting genes for light-sensitive proteins into brain cells, he can selectively activate or de-activate specific neurons with fiber-optic implants. With this unprecedented level of control, he’s managed to cure mice of analogs … Continue reading →

A New Look at “Filler Cells” in the Brain Reveals Their Role in Learning
Janelle Weaver PLoS When we learn associations between items or ideas, such as the value of currency used in a foreign country, the connections between certain brain cells become stronger. In the cellular process thought to underlie learning and memory—long-term … Continue reading →

Human Brains Wire Up Slowly but Surely
Source: Science Mag As the father-to-son exchange in the old Cat Stevens song advised, “take your time, think a lot, … think of everything you’ve got.” Turns out the mellow ’70s folkie had stumbled upon what may explain a key … Continue reading →

Brain cells made from skin could treat Parkinson’s
Source: New Scientist People with Parkinson’s disease might one day be treated with brain cells made from their own skin. Two teams of researchers have independently worked out how to turn skin cells into specialised neurons that make dopamine. This … Continue reading →
