The assessment and treatment of pain in infants is difficult because infants cannot verbally report their experience. In this video we describe quantitative electrophysiological methods and analysis techniques that can be used to measure the response to noxious events from the infant nervous system.

Here we demonstrate a novel assay to study cold nociception in Drosophila larvae. This assay utilizes a custom-built Peltier probe capable of applying a focal noxious cold stimulus and results in quantifiable cold-specific behaviors. This technique will allow further cellular and molecular dissection of cold nociception.

Here, we describe a rapid reliable and simple procedure to determine the lowest temperature at which rats or mice show nocifensive behavior, i.e. the thermal nociceptive threshold (TNT). This method applies a slowly increasing thermal stimulus allowing precise and reproducible estimation of TNTs with minimum, if any, stress to the animals.

Habituation: Studying Infants Before They Can Talk

Source: Laboratories of Nicholaus Noles, Judith Danovitch, and Cara Cashon—University of Louisville Infants are one of the purest sources of information about human thinking and learning, because they’ve had very few life experiences. Thus, researchers are interested in gathering data from infants, but as participants in experimental research, they are a challenging group to study. Unlike older children and adults, young infants are unable to reliably speak, understand speech, or even move and...

Nociception—the ability to feel pain—is essential for an organism’s survival and overall well-being. Noxious stimuli such as piercing pain from a sharp object, heat from an open flame, or contact with corrosive chemicals are first detected by sensory receptors, called nociceptors, located on nerve endings. Nociceptors express ion channels that convert noxious stimuli into electrical signals. When these signals reach the brain via sensory neurons, they are perceived as pain. Thus, pain helps the...
FAQs
These stimuli activate peripheral nociceptors, which initiate signals that travel through spinal pathways toward the developing brain. Although the stimulus types differ, each can engage neural processing associated with potentially tissue-damaging events. Examining these pathways helps neuroscience researchers distinguish how varied clinical or environmental stimuli may produce different patterns of infant responses.
Sensory processing and descending modulation change during early life, so the same noxious input may not be handled in the same way at every developmental stage. These differences affect how neural activity and observable responses should be interpreted. Developmental context is therefore essential when studying infant pain mechanisms or evaluating responses across neonatal populations.
Signals carried through spinal pathways reach a brain that is still developing, making central processing an important part of infant nociception. Brain maturation can shape how incoming signals are processed and integrated with other responses. This relationship helps explain why infant nociceptive behavior and physiology cannot be interpreted solely from peripheral stimulus detection.
Researchers can combine behavioral and physiological measures to evaluate infant responses to potentially painful events. This approach provides observable and bodily indicators when verbal reporting is unavailable. Using both types of information supports more objective pain assessment and helps distinguish changes associated with nociceptive processing from conclusions based on communication alone.
Knowledge of infant nociceptive pathways and developmental processing supports decisions about analgesic and procedural care in neonates. Research can connect the characteristics of a procedure with measurable behavioral or physiological responses, helping clinicians and investigators evaluate whether care adequately addresses infant pain. The neuroscience context also emphasizes that early life requires developmentally informed assessment.
Early painful experiences are studied because they may influence later sensory and neurological development. Investigators can examine infant responses alongside developmental outcomes to explore how nociceptive events relate to subsequent changes. This research broadens infant nociception beyond immediate pain assessment and connects neonatal experiences with longer-term questions in neuroscience.
