New research could reduce the risk of sudden cardiac death

Around 26 million people worldwide suffer from heart failure, with more than 50 per cent dying suddenly most likely due to the spontaneous onset of a heart rhythm problem, known as an arrhythmia. The link between the electrical ...

Why the brain is more reluctant to function as we age

New findings, led by neuroscientists at the University of Bristol and published this week in the journal Neurobiology of Aging, reveal a novel mechanism through which the brain may become more reluctant to function as we ...

Neuroscience

Efficient signal transmission at sensory system synapses

(Medical Xpress)—Neurophysiologist like to think of neurons as communicating with spikes. If that were the whole story, it might be possible to imagine spike codes which could then be used to estimate the flow of information, ...

Neuroscience

Learning requires rhythmical activity of neurons

The hippocampus represents an important brain structure for learning. Scientists at the Max Planck Institute of Psychiatry in Munich discovered how it filters electrical neuronal signals through an input and output control, ...

Neuroscience

Protecting the brain when energy runs low

Researchers from the Universities of Leeds, Edinburgh and Dundee have shed new light on the way that the brain protects itself from harm when 'running on empty.'

Neuroscience

Engineers record neurons to pinpoint synaptic links

It's a mystery how human thoughts and dreams emerge from electrical pulses in the brain's estimated 100 trillion synapses, and Rice University neuroengineer Chong Xie dreams of changing that by creating a system that can ...

Rhythm is it: Ion channels ensure the heart keeps time

The heartbeat is the result of rhythmic contractions of the heart muscle, which are in turn regulated by electrical signals called action potentials. Action potentials result from the controlled flow of ions into heart muscle ...
