Using light pulses, Berlin scientists have recently managed to control theta oscillations in brains of lab mice. They discovered that these brain waves coordinate movement, enabling signaling between distant brain regions, a common code for controlling mental states and behavior. Theta oscillations were discovered in Berlin-Buch almost 80 years ago, but despite decades of intensive… Read more

Brown University researchers have created a new type of optoelectronic implantable device to access brain microcircuits, synergizing a technique that enables scientists to control the activity of brains cells using pulses of light. The invention is a cortical microprobe that can stimulate multiple neuronal targets optically by specific patterns on micrometer scale while simultaneously recording… Read more

To understand how life works, figure out the proteins first. DNA is the architect of life, but proteins are the workhorses. After proteins are built using DNA blueprints, they are constantly at work breaking down and building up all parts of the cell—ferrying oxygen around the body, sending signals to patch wounds, transmitting thoughts across… Read more

For the first time, scientists can now use skin samples from older patients to create brain cells without rolling back the youthfulness clock in the cells first. The new technique, which yields cells resembling those found in older people’s brains, will be a boon to scientists studying age-related diseases like Alzheimer’s and Parkinson’s.

Researchers have reconstructed part of a juvenile rat cortex with the help of a supercomputer. To learn how something works, one strategy is to take it apart and put it back together again. For 10 years, a global initiative called the Blue Brain Project—hosted at the Ecole Polytechnique Federale de Lausanne (EPFL)—has been attempting to… Read more
