Why You Sometimes Don’t Feel Pain Until It’s Too Late

New research highlights how the brain’s own chemistry can suppress pain, explaining why severely injured individuals, like WWII soldiers, sometimes feel little discomfort. The key lies in a brain region called the periaqueductal grey (PAG), which dampens pain signals before they reach conscious awareness.

Oral Health Tied to Migraines and Fibromyalgia Pain in Women

Poor oral health is significantly linked to increased migraine, abdominal, and musculoskeletal pain in women, particularly those with fibromyalgia. Researchers identified specific oral microbes associated with higher pain scores, highlighting a potential gut-brain-oral microbiome connection.

Female Hormones Trigger Pain Relief via Immune Cells

Scientists have discovered that female hormones like estrogen and progesterone can trigger immune cells near the spinal cord to release natural opioids, easing pain before it reaches the brain. These immune cells, known as T regulatory cells (T-regs), are located in the meninges and produce the painkilling molecule enkephalin in response to hormonal signals.

Rubber Hand Illusion Reduces Pain Perception

A new study shows that the rubber hand illusion can reduce the intensity of pain caused by heat. Researchers found that when participants viewed a rubber hand being illuminated while their hidden hand received a heat stimulus, they reported feeling less pain.

Nature’s Painkiller: How Virtual Scenes Ease Pain in the Brain

Viewing natural scenes can significantly reduce how people perceive pain, a new neuroimaging study has found. Researchers discovered that participants reported less pain and exhibited altered brain activity associated with pain perception while looking at virtual nature, compared to urban or office environments.

Cannabis Terpenes Offer New Hope for Chronic Pain, Fibromyalgia

New research has identified cannabis-derived terpenes—compounds that give plants their distinctive aroma—as effective treatments for fibromyalgia and post-surgical pain. In preclinical mouse models, terpenes such as geraniol and linalool significantly reduced chronic pain, providing promising alternatives to opioid medications and avoiding THC's psychoactive side effects.

This shows a brain and neurons representing pain.

Brain Distinguishes Pain and Itch Using Separate Neural Circuits

A new study reveals that pain and itch are processed by distinct neural circuits in the anterior cingulate cortex (ACC). Researchers identified two types of neurons—one responding to both stimuli and another selectively activated by either pain or itch.

How CBD Modulates THC’s Impact on the Brain

Researchers have identified how CBD interacts with cannabinoid receptors to mitigate the negative effects of THC, the psychoactive component of cannabis. Unlike THC, which fully activates the receptor and causes side effects like memory loss and addiction, CBD acts as a modulator, fine-tuning receptor activity.

Brain Oscillations Decode Pain Intensity

Parvalbumin (PV) interneurons in the primary somatosensory cortex (S1) have been identified as key players in encoding pain intensity and driving gamma oscillations, according to a study. Cross-species experiments confirmed that gamma oscillations in S1 selectively reflect pain levels in humans and are linked to PV interneuron activity in rodents. Optogenetic manipulation of these interneurons demonstrated their ability to modulate pain-related behaviors, solidifying their role in pain processing.

New Target for Chronic Pain Identified

Researchers have identified a natural substance, hederagenin, that blocks the NPFFR1 receptor, a protein involved in pain perception in the brain and spinal cord. NPFFR1 has long been a challenging target due to its similarities to related receptors, but advanced screening and computer modeling revealed its unique binding mode.

Healthy Diet Linked to Reduced Chronic Pain

Chronic pain, affecting millions worldwide, may be alleviated by adopting a healthy diet, according to new research. A new study found that eating more vegetables, fruits, grains, lean proteins, and dairy was linked to less pain, especially among women, regardless of body weight.

This shows nerve growth factor receptor TrkA.

A Novel Pain Signaling Complex Discovered

Researchers identified a new receptor, neuropilin-1 (NRP1), which collaborates with a known receptor to regulate pain signaling from nerve growth factor. Unlike traditional signaling receptors, NRP1 acts as a co-receptor to enhance pain signals without directly transmitting them. The study showed how blocking NRP1 or disrupting its interaction with nerve growth factor could offer novel approaches to pain treatment.
