A key approach to understanding the brain is to observe the behavioral effects of turning on specific populations of neurons. One of the most popular approaches to controlling neuronal activity in ...

Scientists at The Hospital for Sick Children (SickKids) have identified a key gene that could lead to next-generation treatments for medulloblastoma, the most common malignant brain tumor in children.

Ion channels in the nervous system are among the most important targets for insecticides. Understanding the structure of the channels is key for the identification of novel species-specific binding ...

Potassium channels play a pivotal role in the regulation of T cell activation, proliferation and survival—key processes underpinning modern immunotherapeutic strategies. Two principal families, the ...

Potassium (K +) channels are small, highly specialized conduits within every living cell that are responsible for the extremely selective and rapid transport of K + ions across cell membranes. Voltage ...

Two studies by scientists at the University of Chicago have demonstrated a new way to look into the inner workings of cells—in particular, to track the flow of ions inside the many tiny organelles ...
