Assessing Body Temperature - Rectal
0 Views •
2025
Rectal temperature measurement is considered the most precise method for assessing core body temperature and typically registers higher than oral temperature. For adults, the rectal thermometer should be inserted 1 to 1.5 inches into the rectum to obtain the most accurate reading. Follow these steps for rectal temperature assessment: Step 1: Perform hand hygiene and don clean gloves to prevent cross-infection. Step 2: Position the patient in a side-lying position to better visualize the rectal...

Source: Joseph Donroe, MD, Internal Medicine and Pediatrics, Yale School of Medicine, New Haven, CT While its usefulness in cancer screening is debated, the male rectal examination remains an important part of the physical exam. The exam is indicated in selected patients with lower urinary tract symptoms, urinary and/or fecal incontinence or retention, back pain, anorectal symptoms, abdominal complaints, trauma patients, unexplained anemia, weight loss, or bone pain. There are no absolute...

Local Heat Probe Assay: A Method to Assess Nociception of High Temperatures in Drosophila Larvae
0 Views •
2023
Drosophila larvae have dedicated sensory neurons–nociceptors–whose response to potentially harmful thermal stimuli triggers aversive–or so-called "nocifensive"–behaviors in the animal. This video describes a method to assess thermal nociception by recording larval behavior in response to local application of a heat probe onto the cuticle. This method is, therefore, called the local heat probe assay.

FAQs
The sensing element detects temperature changes at the rectal measurement site and sends those changes to a recording system. Thermistors and thermocouples are the sensor types identified for this purpose, allowing researchers to monitor physiological temperature over time. This recorded signal supports analysis of changing thermal states during neural, behavioral, pharmacological, or environmental experiments.
Core temperature provides a physiological measure that can be interpreted alongside neural activity and behavior. Changes in temperature may accompany altered thermoregulation, metabolism, fever responses, circadian rhythms, or neural stimulation. Including this readout helps researchers relate brain processes to whole-body regulation rather than examining neural signals in isolation.
Controlled conditions make temperature changes easier to associate with the experimental factor being studied. Because the probe records a physiological response during defined challenges or interventions, researchers can compare thermal patterns with neural and behavioral data under the same conditions. This improves interpretation of effects linked to drugs, neural stimulation, metabolism, or environmental exposure.
Thermoregulation depends on coordinated physiological control of body temperature, making a core-temperature readout important for tracking that process. A rectal measurement can reveal temperature changes associated with regulatory responses, fever, environmental challenges, or neural manipulation. In neuroscience, these data help connect temperature control with brain activity and resulting behavior.
Under controlled experimental conditions, the sensor is gently inserted into the rectum, positioned for measurement, and connected to a recording system that captures temperature changes. Researchers then track the resulting readings over time and relate them to the planned neural, behavioral, drug, stimulation, metabolic, or environmental manipulation.
This approach is useful when an experiment needs a physiological temperature measure during studies of thermoregulation, circadian rhythms, fever responses, metabolism, or neural stimulation. It can also support experiments involving drugs or environmental challenges. The measurement becomes especially informative when collected together with neural and behavioral observations.
Combined recordings can show how changes in brain activity relate to whole-body physiological regulation. Depending on the study, researchers may examine temperature patterns associated with circadian timing, fever, metabolism, neural stimulation, drugs, or environmental challenges. The temperature record therefore adds a physiological outcome that complements neural and behavioral measurements.
