What does myelin actually do?

Students of physiology are invariably taught that the primary function of myelin is to insulate nerves. In particular, to make action potentials more efficient by increasing the thickness of the membrane and thereby decreasing ...

Scientists key in on brain's mechanism for singing, learning

New research reveals that specialized cells within neural circuitry that triggers complex learning in songbirds bears a striking resemblance to a type of neural cell associated with the development of fine motor skills in ...

Simultaneous optical and electrical tracking of heart activity

It is still elusive to what extent interactions between different cell types of the heart influence the normal heart rhythm and possibly trigger life-threatening arrhythmias. A new measurement method developed at the University ...

Stem cells and mathematical models: The future of medical research

Human induced pluripotent stem cells (hiPSCs), which can be differentiated into cardiac myocytes, are used in a wide variety of applications such as developing patient-specific disease models, or the evaluation of novel therapeutic ...

Neuroscience

From imaging neurons to measuring their true activity

When neurons communicate with each another, they transmit—or "fire"—small electrical impulses called action potentials or spikes. These action potentials are the fundamental units of information processing in the brain. ...

MRI expertise aids research on hemodialysis therapy patients

Researchers at the Beckman Institute for Advanced Science and Technology were part of a collaborative effort to investigate a new strategy to manage sodium levels in patients with kidney failure who were undergoing hemodialysis ...

Why failing hearts love hard workouts

"Our research on rats with heart failure shows that exercise reduces the severity of the disease, improves heart function and increases work capacity. And the intensity of the training is really importance to achieve this ...
