Novel sensors enable precise measurement of dopamine

Dopamine is an important signaling molecule for nerve cells. Its concentration could not be precisely determined with both high spatial or temporal resolution until now. A new method has now made this possible: A research ...

Researchers map rotating spiral waves in live human hearts

Electrical signals tell the heart to contract, but when the signals form spiral waves, they can lead to dangerous cardiac events like tachycardia and fibrillation. Researchers at the Georgia Institute of Technology and clinicians ...

Understanding how we use the past to predict the future

Recent research has offered strong evidence that the brain, when it is confronted with a specific stimulus, uses 'predictive coding' to create a mental expectation about what is going to happen next.

Live monitoring of brain metabolism with fluorescence

Lactate is generated in the body as a byproduct during normal metabolism and exercise. While considered a useless waste product for a long time, recent studies have shown that lactate can be an indicator for cancer and various ...
