Introduction: Lumbopelvic pain, prevalent in 60-70% of pregnant women, persists in approximately half up to 12 months postpartum, and 20% even 3 years after childbirth. Effective treatment for pregnancy-related lumbopelvic pain is challenging, prompting variable interventions from medications to physical therapies. European guidelines advocate an active approach, incorporating patient education and exercise prescription. This project innovatively employs pain neuroscience education for pregnant women with lumbopelvic pain, a strategy proven effective in musculoskeletal pain but unexplored in p

…Among these, pain is one of the most frequent,affecting around 85% of patients and contributing to a deterioration in their quality of life.Nowadays, pain treatment in PD is still inefficient due to the lack of knowledge of the underlyingmechanisms. However, we know that pain can be modulated by the monoaminergic descendingpathways projecting to the dorsal horn of the spinal cord (DHSC). Thus, the aim of the present studyis to unravel the involvement of th

Pain is considered one of the most frequent non-motor symptoms of Parkinson’s disease (PD) and it usually manifests before the motor symptoms. Although not considered one of the cardinal symptoms of PD, pain affects up to 80% of PD patients and half of them report multiple types of pain. The cause of this pain is still unknown, but it may be due to dysfunction of key nuclei in the processing of nociceptive information.In order to determine the possible causes of this prodromal symptom, we use different parkinsonian models, such as the hα- syn1-120 model, which presents a differential expressio

…We aimed to uncover how age, pain, and itch influence the patterns of behavioral sequences and their transitions in freely behaving animals using MoSeq, a machine learning network analysis tool developed by the Datta lab. Mice of different ages were treated with chloroquine (itch) or formalin (pain) and placed in an open field arena and recorded for 30 minutes via a high-speed color camera and infrared depth camera. A trained autoregressive hidden Markov model classified the mouse movements into sub-second syll

Pain is one of the non-motor symptoms affecting quality of life in Parkinsonian patients. More than 80% of patients suffer from pathological nociceptive hypersensitivity, which may be due to changes in the processing of somatosensory information in basal ganglia, including the subthalamic nucleus (STN). However, the underlying mechanisms are not yet defined.The aim of this study was i) to characterize the responses of STN neurons to peripheral nociceptive stimulation under normal and pathological conditions and ii) to investigate the effects of deep brain stimulation (DBS) of the STN on nocice

Pain is constructed in the brain by integrating multimodal information, ranging from noxious inputs to expectations. Previous studies have identified brain systems that mediate the effects of different components of pain, but the computational mechanisms of their integration have been understudied. Here we examined whether the neural trajectories of different component subspaces would reveal the computational principles of information integration. To this end, we conducted a cue-induced pain expectation experiment with functional Magnetic Resonance Imaging in humans (N = 56) to examine the com

We provide protocols for the social transfer of pain and analgesia in mice. We describe the steps to induce pain or analgesia (pain relief) in bystander mice with a 1-h social interaction with a partner injected with CFA (complete Freund’s adjuvant) or CFA and morphine, respectively. We detail behavioral tests to assess pain or analgesia in the untreated bystander mice. This protocol has been validated in mice and rats and can be used for investigating mechanisms of empathy. Highlights • A protocol for the rapid social transfer of pain in rodents • Detailed requirements for handling and housin

“Of pain you could wish only one thing: that it should stop. Nothing in the world was so bad as physical pain. In the face of pain there are no heroes.- George Orwell, ‘1984’ " "Neuroscience has revealed the secrets of the brain and nervous system to an extent that was beyond the realm of imagination just 10-20 years ago, let alone in 1949 when Orwell wrote his prophetic novel. Understanding pain, however, presents a unique challenge to academia, industry and medicine, being both a measurable physiological process as well as deeply personal and subjective. Given the millions of people who suff

We have been developing Brain-Computer Interface (BCI) using electrocorticography (ECoG) [1] , which is recorded by electrodes implanted on brain surface, and magnetoencephalography (MEG) [2] , which records the cortical activities non-invasively, for the clinical applications. The invasive BCI using ECoG has been applied for severely paralyzed patient to restore the communication and motor function. The non-invasive BCI using MEG has been applied as a neurofeedback tool to modulate some pathological neural activities to treat some neuropsychiatric disorders. Although these techniques have bee

Patapoutian explains how experiments on mechanically sensitive cells led to the discovery of PIEZO channels and their roles in detecting force. The lectures connect the search for individual molecules with broader questions about touch, body position and the sensing

Pain has both a sensory and emotional component and is driven by activation of sensory neurones called nociceptors that are tuned to detect noxious stimuli in a process called nociception. Although nociception functions as a detect and protect mechanism. and is found in many organisms, this system becomes dysregulated in a number of conditions where chronic pain presents as a key symptom, for example osteoarthritis. Nociceptors do not innervate empty space though and do not act alone. Going beyond the neurone, other cell types, such as fibroblast-like synoviocytes interact with and modify the

Pain is a major clinical problem affecting 1 in 5 people in the world. There are unresolved questions that urgently require answers to treat pain effectively, a crucial one being how the feeling of pain arises from brain activity. Computational models of pain consider how the brain processes noxious information and allow mapping neural circuits and networks to cognition and behaviour. To date, they have generally have assumed two largely independent processes: perceptual and/or predictive inference, typically modelled as an approximate Bayesian process, and action control, typically modelled a

The ability to experience pain is old in evolutionary terms. It is an experience shared across species. Acute pain is the body’s alarm system, and as such it is a good thing. Pain that persists beyond normal tissue healing time (3-4 months) is defined as chronic – it is the system gone wrong and it is not a good thing. Chronic pain has recently been classified as both a symptom and disease in its own right. It is one of the largest medical health problems worldwide with one in five adults diagnosed with the condition. The brain is key to the experience of pain and pain relief. This is the plac

Candy will provide an overview of Bristol Health Partners' Chronic Pain Health Integration Team which brings together clinicians, academics, patients and carers to focus on improving the lives of those with chronic pain and supporting those who provide chronic pain services or care. Tony will describe recent and ongoing studies that have been forward and reverse translating pain neuroscience from animal to human including functional imaging in patients, microneurography, industrial partnerships and trials of novel preventative approaches that are benefitting from the people, expertise and fac

Paclitaxel, a chemotherapeutic drug, for example is associated with high incidence of peripheral neuropathy, around 71% of the patients of which 27% of these develop neuropathic pain. Use of cannabis or phytocannabinoids has been reported to improve pain measures in patients with neuropathic pain, including painful HIV-associated sensory neuropathy and cancer pain. Phytocannabinoids and endocannabinoids, such as anandamide and 2-arach

The Chiu laboratory focuses on neuro-immune interactions in pain, itch, and tissue inflammation. Dr. Chiu’s research has uncovered molecular interactions between the nervous system, the immune system and microbes that modulates host defense. He has found that sensory neurons can directly detect bacterial pathogens and their toxins to produce pain. Neurons in turn release neuropeptides that modulate immune cells in host defense. These interactions occur at major tissue barriers in the body including the gut, skin and lungs. In this talk, he will discuss these major neuro-immune interactions and
