Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people. Surveys allow researchers to gather data from larger samples than may be afforded by...

Label-Free Neutrophil Separation from Tracheal Secretion Using Spiral Microfluidics Channel
0 Views •
2025
This video demonstrates separating neutrophils from tracheal secretions using a microfluidic device with spiral channels. The device achieves efficient separation based on cell size by utilizing varying thicknesses and trapezoidal-shaped channels. The interplay between forces results in large neutrophils accumulating near the inner wall while erythrocytes and mucin aggregates remain near the outer wall, ensuring effective neutrophil separation.

This video demonstrates the process for isolating spiral ganglion explants from the inner ear and co-culturing them with the organ of Corti on a multielectrode array. Spiral ganglia are carefully extracted and sectioned into smaller tissue sections or explants. These explants are cultured on the multielectrode array's active area to promote neuronal process outgrowth.

Surveying is the art and science of mapping the earth's surface. It involves measuring distances, angles in horizontal or vertical directions, and levels to understand the shape and size of land features. Surveying techniques are essential for various tasks, such as identifying the levels of a land area with reference to a specific point, and mapping undulations and water bodies.There are two main types of surveying: plane surveys and geodetic surveys. Plane surveys assume the earth is flat,...

We present a protocol to culture primary murine spiral ganglion neuron explants on multi electrode arrays to study neuronal response profiles and optimize stimulation parameters. Such studies aim to improve the neuron-electrode interface of cochlear implants to benefit hearing in patients as well as the energy consumption of the device.
FAQs
The central point provides a spatial reference for organizing observations and interpreting environmental change. Measurements collected along the route can be related to their distance from that point, helping investigators examine whether species presence, habitat features, soil, vegetation, or other field variables change as the survey moves inward or outward. This connection gives the dataset a clear geographic framework.
A spiral route can reveal how environmental conditions vary across distance from a source, center, or disturbance. For example, observations may show changes in species presence, habitat features, soil, or vegetation along the route. The resulting pattern helps characterize spatial variation rather than treating the surveyed area as environmentally uniform.
Defined observation locations connect each measurement to a specific position within the surveyed area. This allows surveyors to relate field findings to movement along the spiral and to compare conditions at different distances or parts of the route. Recording measurements consistently at planned locations strengthens the spatial interpretation of species, habitat, soil, and vegetation observations.
Surveyors should establish the focal central point, determine whether the route will move inward or outward, and identify where observations will be recorded along the path. They should also decide which environmental variables to document, such as species presence, habitat features, soil, or vegetation. This planning links route coverage with the intended environmental question.
The approach can accommodate observations of species presence, habitat features, soil conditions, vegetation, and other field variables identified for the study. Surveyors record these measurements at planned locations as they follow the route. Combining the route position with the observations helps describe how multiple environmental characteristics vary across the focal area.
This approach is useful when investigators need systematic coverage around a focal site or want to examine spatial change linked to distance. Environmental applications include ecological monitoring, habitat assessment, pollution studies, and field-based research. It can support characterization of conditions around a source, center, or disturbance by organizing observations along a continuous planned route.
