Calcium controls sleep duration in mice

University of Tokyo and RIKEN researchers have identified seven genes responsible for causing mice to stay awake or fall asleep based on a theoretical model of sleep and on experiments using 21 different genetically-modified ...

'Lightning bolts' in the brain show learning in action

Researchers at NYU Langone Medical Center have captured images of the underlying biological activity within brain cells and their tree-like extensions, or dendrites, in mice that show how their brains sort, store and make ...

'Radiogenetics' seeks to remotely control cells and genes

It's the most basic of ways to find out what something does, whether it's an unmarked circuit breaker or an unidentified gene—flip its switch and see what happens. New remote-control technology may offer biologists a powerful ...

A faster vessel for charting the brain

Princeton University researchers have created "souped up" versions of the calcium-sensitive proteins that for the past decade or so have given scientists an unparalleled view and understanding of brain-cell communication.

Ultrasensitive calcium sensors shine new light on neuron activity

Every time you say a word, take a step, or read a sentence, a collection of neurons sends a speedy relay of messages throughout your brain to process the information. Now, researchers have a new way of watching those messages ...

Visualizing a memory trace

In mammals, a neural pathway called the cortico-basal ganglia circuit is thought to play an important role in the choice of behaviors. However, where and how behavioral programs are written, stored and read out as a memory ...
