New microscopy technique peers deep into the brain

In order to understand the brain, scientists must be able to see the brain—cell by cell, and moment by moment. However, because brains comprise billions of microscopic moving parts, faithfully recording their activity comes ...

New light sensing molecule discovered in the fruit fly brain

Six biological pigments called rhodopsins play well-established roles in light-sensing in the fruit fly eye. Three of them also have light-independent roles in temperature sensation. New research shows that a seventh rhodopsin, ...

A barrier against brain stem cell aging

Neural stem cells generate new neurons throughout life in the mammalian brain. However, with advancing age the potential for regeneration in the brain dramatically declines. Scientists of the University of Zurich now identified ...

Brain folding

The neocortex is the part of the brain that enables us to speak, dream, or think. The underlying mechanism that led to the expansion of this brain region during evolution, however, is not yet understood. A research team headed ...

Siberian hamsters show what helps make seasonal clocks tick

Many animals, including humans, have internal clocks and calendars to help them regulate behavior, physiological functions and biological processes. Although scientists have extensively studied the timekeeping mechanisms ...
