It’s normal to have an upset tummy when you’re nervous.
When we get nervous, a number of processes occur in the brain that are passed onto the stomach and affect the digestive process. This is a hangover from our hunter-gatherer days.
Running around like a…
There was once a chicken called Miracle Mike who lived for 18 months without a head: it's all to do with nerves.
A boy with a paper cut.
Ouch! Who hasn't felt the effects of a paper cut and then cursed the gods or themselves for the injury? But have you ever wondered why they hurt so much? A professor of family medicine explains why.
Oui! There is more than one way to navigate to the Eiffel Tower.
Brain signals might work like people navigating without a map – and it's actually more efficient than you think.
Enzymes, the catalysts of biology, can engulf and break down hundreds of nerve agent molecules per second.

Scientists invented chemical weapons; some are now working to destroy them. New biomolecular design techniques let researchers design proteins that can destroy nerve agents in bodies.

Brain-computer interfacing is a hot topic in the tech world, with Elon Musk's announcement of his new Neuralink startup. Here, researchers separate what's science from what's currently still fiction.
Neuroscientists are questioning how it is that physical matter comes together to make the mind.
“Fluttering” of butterflies is often a nervous response.
We asked an expert to explain why we get that odd fluttering feeling when we are nervous.
Who’s making the decisions around here?

Different animals and different behaviors rely on various forms and combinations of 'government' to carry out desired actions.
Just how quickly are those thoughts bouncing around in there?

Sensory information comes into the system, and we initiate actions in response. Quantifying how quickly that happens is tricky – especially since our own perceptions of the timing aren't quite right.
Try putting an ice-cube in your mouth. The insides of your mouth and tongue instantly turn numb. Hold it in still and you will feel pain. Now try sucking on peppermint. The mint itself is at room temperature…
Regenerating the nerves that can return function to our spinal cords.
Spinal cord injuries are currently irreparable. When nerve fibres in the central nervous system are damaged there is, as yet, no way of reversing this. But research we’ve been doing has led to the discovery…
Researchers have found the first evidence that stomach nerves act as a clock that limits eating to specific times of the…
The application of radio currents can help reduce the level of blood pressure in patients with severe hypertension, according…
Making the most of old connections.
Researchers have been able to restore mobility in paralysed rats using a technique called deep brain stimulation. This involved…
New research could restore feeling to prosthetic limbs.
A method for restoring feeling and action to amputees and others who have lost their sense of touch has been established…
Technology adapted from inkjet printers could soon be used to print living human cells onto biodegradable polymer scaffolds…
Scientists have constructed a mathematical model which predicts how nerve fibres make connections during brain development…
The nervous system of the common roundworm is being used to study nerve-based conditions and nerve degeneration with the…
A newly developed neuroprosthesis allows paralysed limbs to move voluntarily by sending messages from the brain to the muscles…
