How it works: The protein that stimulates muscle growth

In the gym, you are not just pumping iron, you are oxygenating muscle cells which keeps those muscles healthy, strong and growing—a process called hypertrophy, or an increase in muscle mass due to an increase in muscle ...

Enzyme prevents brain activity from getting out of control

Our bodies have the ability to modify the contacts between neurons. Among other things, this is how it prevents brain activity from getting out of control. Researchers from the University Hospital Bonn, together with a team ...

In the quest for a TBI therapy, astrocytes may be the bull's-eye

Growing evidence suggests that traumatic brain injury (TBI) is an important risk factor for developing Alzheimer's disease and dementia. But to date, effective therapies aren't available for preventing or treating TBI-induced ...

A drug from resin to combat epileptic seizures

New molecules, developed by researchers at Linköping University, Sweden, have promising properties as possible drugs against epilepsy. A study published in the journal Epilepsia shows that several of the molecules have antiseizure ...

Neuroscience

Balancing brain cell activity

To process information in our brains, nerve cells produce brief electrical impulses, called action potentials, triggered from one highly specialized region. Research from the Netherlands Institute for Neuroscience, together ...

Action potential

An action potential (or nerve impulse) is a transient alteration of the transmembrane voltage (or membrane potential) across an excitable membrane generated by the activity of voltage-gated ion channels embedded in the membrane. Action potentials play multiple roles in several types of excitable cells such as neurons, myocytes, and electrocytes. The best known action potentials are pulse-like waves of voltage that travel along axons of neurons.
