Educational series on pain for NIH Intramural Research Training Award trainees
Note:
- You must register with your National Institutes of Health (NIH) email address. Register once for all sessions in the current series.
- You may attend in person or online, as your schedule permits.
- All sessions meet from 3–4 p.m.
The Interactive Pain Lecture Series (IPLS) is an educational lecture series, which provides an overview of pain as a pathophysiological phenomenon from transduction and transcription, to transmission and modulation, to psychosocial experience and coping with pain that translates into behavior, and all the physiology and phenomenology in between following an established pain education curriculum.
This lecture series provides a foundation for participants in the Intramural Research Training Award (IRTA) program to learn basic concepts and facts about pain in its full dynamic complexity and translatability across its multiple domains, from physiology to behavior and from research to clinic. The intended primary audience for this series is National Institutes of Health (NIH) postbacs, postdocs, and other students and fellows (graduate and medical students, summer students, etc.) in the IRTA program. However, all NIH intramural staff are invited to attend, as many topics are likely to be of interest to intramural clinicians.
Spring 2024 Session
The topics presented during this spring semester were also presented in part during the 2023 spring and fall semesters, and the current lecture series will complement what was presented last year.
This spring lecture series consists of 10 1-hour sessions. Lectures will take place on the second and fourth Wednesdays of the month from 3 to 4 p.m. ET. Each session will be a hybrid of in-person participation on the NIH campus and online remote participation. An outline of each upcoming session’s presentation will be made available to the registered audience 2 days prior to the session.
Each 60-minute session will consist of a 25- to 30-minute presentation delivered by one or two presenters, who will describe and review specific pain topics. A panel discussion and Q&A with the audience will follow the presentation for the remainder of the hour. Volunteer postbacs will introduce the topics, presenters, and discussants, as well as moderate the discussions. Those attending in person as well as those attending remotely are invited to participate in the discussion to reflect the truly interactive nature of this course.

Why study pain?
Definitions of pain; biological significance of pain; nociceptive, nociplastic, and neuropathic pain
In the first part of this session participants in this session will present critical reasons why it is important to learn about pain, conduct research about pain, and present pain in a way that would be accessible to NIH IRTA participants. During the second half of this session, we will review definitions of pain and a few major categories of pain.

Overall anatomy and physiology of pain across organ systems—neural basis and contribution of other organ systems
Pain is a complex biological phenomenon subserved primarily by the nervous system, from peripheral nerve receptors to cortical neurons and other peripheral nervous system and central nervous system structures, which interact along the way. This session will review the general organization of the nociceptive system that underlies the experience of pain as well as the contribution of other systems, such as the immune system.

Peripheral mechanisms: transduction of injury and noxious stimulation, transmission, excitability and sensitization
Noxious stimulation and tissue injury set into motion a cascade of events from receptors that transduce the force of injury and translate it into action potentials in the peripheral sensory nerve fibers. As a result of injury, the peripheral immune system and other tissues respond, leading to a hyperexcitable state of peripheral nerve fibers known as peripheral sensitization. Manifestations of this sensitization are ongoing pain, allodynia, and hyperalgesia.
March 22, 2023
Central transmission, central sensitization, and dorsal horn circuits
As nociceptive peripheral afferents, peripheral nerve fibers connect to the spinal cord via the dorsal horn and from there via specialized fiber tracts project to the brainstem and thalamus. From there, nociceptive signals project to multiple areas of the brain, where multiple dimensions of pain are experienced. With sustained input from the periphery, central circuits themselves become sensitized leading to central sensitization, which also contributes to the experience of ongoing pain, allodynia, and hyperalgesia.
April 12, 2023
Central modulation and descending control
In the previous sessions, we presented peripheral and central transmission, where information is transmitted from the site of injury that initiates nociception and pain, as well as physiological circumstances that enhance that transmission, leading to what is known as sensitization, including peripheral and central sensitization. Sensitization is a contributor to clinical phenomena of allodynia and hyperalgesia. Central sensitization is a part of modulation that occurs in the spinal cord, and this mechanism is intimately linked with descending control mechanisms, which can be impaired in patients with chronic pain.
April 26, 2023
Pain perception and coping with pain
Once the nociceptive transmission reaches the brain, it is distributed to many brain structures, which then contribute to all of the aspects of what we call pain. Until that point, all of the physiological processes are nociception. It is activation of these multiple mechanisms that allows the person experiencing pain to also form their resources to cope with pain, at which point their brain structures become a part of descending pain modulation.

Affective, cognitive, behavioral, psychosocial, and spiritual aspects of pain
Multiple areas of the central nervous system participate in perception of and coping with pain as outlined in the previous presentations. In addition to sensory perception of pain, affective, cognitive, psychosocial, and spiritual factors in perception of pain interact with the environment to result in what is finally the experience of pain that is unique to each person.

Pain measurement and assessment in humans
The preceding sessions of this course presented the complexity of the pain experience in healthy people as well as in people with acute and chronic pain. This session will present overall strategies to assess and measure pain in a variety of clinical circumstances, as well as challenges of obtaining and interpreting that information.

Pain measurement and assessment in animals, including chronic pain models
Animal models are very important for the study of pain mechanisms on a finer anatomical level including molecular approaches and invasive physiological methods, which provide the finer details of pain mechanisms.
June 28, 2023
Animal models of pain and human models of pain
This session will be a grand summary of the IPLS course, demonstrating how animal and human models provide a platform to study pain and pain mechanisms, which are then used to translate that knowledge into approaches for assessment and treatment of pain.
