A question of time

A team led by the Freiburg biologists Prof. Dr. Wolfgang Schamel and Prof. Dr. Wilfried Weber conducted an experiment in which they controlled the duration of the interaction of a specific protein with T cells, a type of ...

A new window into macaque brain connections

Researchers can now see how the two sides of the living brain mirror each other thanks to a new combination-imaging technique. The method dubbed "opto-OISI" takes advantage of rapidly developing high-resolution optical technologies ...

How light triggers brain activity

Optogenetics uses light to control brain processes. It is based on light-controlled proteins such as channelrhodopsin-2, an ion channel that opens when it's exposed to light, thus activating cellular processes. In collaboration ...

Using laser light to study how epilepsy arises in the healthy brain

Scientists at McGill University have developed a new method to study how seizures arise in the healthy brain. Using laser light guided through ultra-thin optic fibers in the brain of rodents, the researchers "turned on" light-sensitive ...

Mapping the neural circuit of innate responses to odors

A team of neuroscientists at the Champalimaud Centre for the Unknown (CCU), in Lisbon (Portugal), has performed one of the first studies into the central neural circuits (or higher brain areas) that underlie innate responses ...
