Source: Richard Glickman-Simon, MD, Assistant Professor, Department of Public Health and Community Medicine, Tufts University School of Medicine, MA This video provides an overview of sinus, nose, and throat examinations. The demonstration begins with a brief overview of the anatomy of the region. The upper third of the nose is bony, and the bottom two-thirds are cartilaginous. Air entering the nares passes through the nasal vestibules and into the narrow passageway between the nasal septum...

A rapid method for volatile compound analysis in fruit is described. The volatile compounds present in the headspace of a homogenate of the sample are rapidly separated and detected with ultra-fast gas chromatography (GC) coupled with a surface acoustic wave (SAW) sensor. A procedure for data handling and analysis is also discussed.

Nose and Nasal Cavity

The nose is composed of an observable exterior segment (external nose) and an internal segment within the skull known as the nasal cavity (internal nose). The external nose, visible on the face, consists of a framework of bone and hyaline cartilage enveloped in skin and muscle and lined with a mucous membrane. This structure is supported by the frontal bone, nasal bones, and maxillary bone and is supplemented by a cartilaginous framework comprising the septal nasal cartilage, lateral nasal...

A novel optical polishing process, called “Convergent Polishing”, which enables faster, lower cost polishing, is described. Unlike conventional polishing processes, Convergent Polishing allows a glass workpiece to be polished in a single iteration and with high surface quality to its final surface figure without requiring changes to polishing parameters.
FAQs
Detection depends on an infrared photobeam or another sensor positioned at the aperture. When the animal inserts its snout, the system registers the event as a nose poke, allowing the response to be counted consistently. That event can also serve as the trigger for a programmed consequence, linking an observable action to a precisely timed experimental event.
The programmed consequence determines what follows a response and therefore what contingency the animal experiences. Depending on the protocol, a nose poke may produce a food pellet, fluid delivery, light, tone, or brief timeout. Changing that consequence allows researchers to examine how behavior is regulated by reinforcement or by other controlled outcomes.
Because each response can be recorded automatically, investigators can quantify response rate rather than relying only on later observation. Nose poke data can support assessments of motivation, attention, learning, and decision-making. The same event record also helps relate behavioral changes to the programmed consequence, making response patterns easier to compare across experimental conditions.
A typical workflow starts by presenting the animal with the chamber and its aperture, then configuring the sensor and the consequence associated with a poke. During testing, the system records detected responses and delivers the programmed event when the relevant condition is met. Researchers can then examine response counts or rates in relation to the task.
This apparatus is useful when a study requires a clearly defined, repeatable response rather than an impression of general activity. Researchers can apply it to experiments on reinforcement, stimulus control, learning, motivation, attention, decision-making, and behavioral flexibility. Its automated recording is especially relevant when the timing and frequency of responses are central outcomes.
In behavior research, the aperture connects an animal’s action with an experimentally controlled event, creating a compact unit for studying response-consequence relationships. That arrangement can reveal whether behavior changes when the consequence or associated stimulus changes. It therefore supports reproducible analysis of investigatory and operant behavior without depending entirely on manual scoring.
