All ears: Genetic bases of mammalian inner ear evolution

Mammals have adapted to live in the darkest of caves and the deepest oceans, and from the highest mountains to the plains. Along the way, mammals have also adapted a remarkable capacity in their sense of hearing, from the ...

Opening the black box of dendritic computing

How do nerve cells compute? This fundamental question drives LMU neurobiologists led by Andreas Herz. They have now presented a novel method to disentangle complex neural processes in a much more powerful way than was previously ...

Mathematician calculates wave velocity for post-stroke therapy

A RUDN mathematician calculated the velocity of wave propagation in the brain in the course of external stimulation. This procedure is used to treat stroke patients. To do so, the scientists generally formulated the task ...

Brain function partly replicated by nanomaterials

The brain requires surprisingly little energy to adapt to the environment to learn, make ambiguous recognitions, have high recognition ability and intelligence, and perform complex information processing.

Rare cells are 'window into the gut' for the nervous system

Specialized cells in the gut sense potentially noxious chemicals and trigger electrical impulses in nearby nerve fibers, according to a new study led by UC San Francisco scientists. "These cells are sensors, like a window ...

Graphene shown to safely interact with neurons in the brain

Researchers have successfully demonstrated how it is possible to interface graphene - a two-dimensional form of carbon - with neurons, or nerve cells, while maintaining the integrity of these vital cells. The work may be ...

How do robots 'see' the world?

The world has gone mad for robots with articles talking almost every day about the coming of the robot revolution. But is all the hype, excitement and sometimes fear justified? Is the robot revolution really coming?

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.
