Hormone levels fluctuate like the tides, ebbing and flowing according to carefully orchestrated cycles. These hormones not only influence the body, but can cross into the brain and shape the behavior ...

Researchers at the Icahn School of Medicine at Mount Sinai have characterized how cellular senescence—a biological process in which aging cells change how they function—is associated with human brain ...

When myelin breaks down, white matter in the brain deteriorates, a change commonly seen with aging. At the same time, microglia, the brain’s primary immune cells, can shift from protective responders ...

Tau proteins act like the brain's maintenance crew, helping maintain the structure and proper function of brain cells. In ...

In a recent study published in Science Advances, a group of researchers assessed whether dendritic spine head diameter in the temporal cortex is a better predictor of episodic memory performance in ...

In 1979, biologist Francis Crick claimed it would be impossible to create an accurate diagram of the brain’s wiring and neuronal activity—even within just a cubic millimeter of brain tissue. Now, a ...

Scientists from the Machine Intelligence from Cortical Networks (MICRONS) consortium have published the microconnectome of a cubic millimeter of the mouse brain. This is the most complete map of this ...

Some brain cells can resist the toxic processes associated with Alzheimer's disease and other forms of dementia. Scientists ...

The brain plays a big part in the aging process, and scientists think they’ve pinpointed the specific cells that control it. In a study of mice, researchers at the Allen Institute identified certain ...
