Four tiny 3D organs connected themselves in a lab dish, forming a replica of the human pain pathway, in a new study. The discovery allows scientists to better understand chronic pain and how pain ...

Scientists created a model of the human pain pathway in a dish by connecting four separate brain organoids. The feat should help them understand sensory disorders like those affecting pain perception.

Researchers integrated four organoids that represent the four components of the human sensory pathway, along which pain signals are conveyed to the brain. Stimulation of the sensory organoid (top) by ...

Stanford Medicine investigators have replicated, in a lab dish, one of the most prominent human nervous pathways for sensing pain. This nerve circuit transmits sensations from the body’s skin to the ...

New research reveals previously unknown ways opioid receptors can function, opening the door to safer pain treatments.

Studies of heart-rate variability – small changes between heartbeats controlled by the vagus nerve – show that swearing may ...

Stanford Medicine investigators have replicated, in a lab dish, one of humans' most prominent nervous pathways for sensing pain. This nerve circuit transmits sensations from the body's skin to the ...

Stress is often seen as a mental and emotional burden, but its effects reach far deeper than most realize. For many, chronic stress doesn’t just weigh on the mind — it can amplify physical pain in ...

A single nerve injury can quietly reshape the immune system across the entire body. Preclinical research from McGill ...

In a study published in Science, researchers at Karolinska Institutet describe the neural processes behind how morphine relieves pain. This is valuable knowledge because the drug has such serious side ...

So when you touch a hot stove, the nerve endings in your fingers react instantly. But the ouch comes a split-second later, when that information finally reaches your brain. Well, now, scientists have ...

Researchers describe the neural processes behind how morphine relieves pain. This is valuable knowledge because the drug has such serious side effects. In a study published in Science, researchers at ...
