Quantifying Respiration using Microrespirometers ExpandNOTE: In this experiment, you will measure the rate of cellular respiration for germinating seeds by measuring the rate of exchange for oxygen. As oxygen is consumed to provide energy, germinating seeds release carbon dioxide. This carbon dioxide is absorbed by potassium carbonate and thus the overall gaseous pressure of the respirometer will be reduced. HYPOTHESES: The experimental hypothesis is that germinating seeds will show a greater...

Autotrophs and Heterotrophs Living organisms require a continuous input of energy to maintain cellular and organismal functions such as growth, repair, movement, defense, and reproduction. Cells can only use chemical energy to fuel their functions, therefore they need to harvest energy from chemical bonds of biomolecules, such as sugars and lipids. Autotrophic organisms, namely plants, algae, and photosynthetic and chemosynthetic bacteria, convert inorganic materials into such biomolecules by...

The scalability and resolution of conventional optical manipulation techniques are limited by diffraction. We circumvent the diffraction limit and describe a method of optically transporting nanoparticles across a chip using a gold surface patterned with a path of closely spaced C-shaped plasmonic resonators.

Frictional Forces on Flat Belts

Flat belts are commonly used in various industrial applications for transmitting power from one pulley to another. When a flat belt is wrapped around a set of pulleys, it experiences different tensions at the driving pulley ends due to the friction between the belt and pulley surface. When the pulley moves in a counterclockwise direction, the tension T2 on the opposite side of the pulley where the belt is moving away from is higher than the tension T1 on the side where the belt is moving...

We describe a protocol for investigating human locomotor adaptation using the split-belt treadmill, which has two belts that can drive each leg at a different speed. We specifically focus on a paradigm designed to test the generalization of adapted locomotor patterns to different walking contexts (e.g., gait speeds, walking environments).
FAQs
The sensing element translates mechanical change into a time-varying electrical trace. As the thorax or abdomen expands, the elastic band stretches; during contraction, it returns in the opposite direction. A strain gauge or inductive sensor captures these changes, so the waveform preserves the timing of inhalation and exhalation and supports estimates of respiratory rate and relative depth.
Signal amplitude should be interpreted as a relative measure of breathing depth, not as a direct measurement of air volume. The belt records changes in chest or abdominal circumference, and those changes vary with expansion and contraction. Consequently, the recording is especially useful for comparing breathing fluctuations within an experiment and relating them to concurrent neural or behavioral events.
Respiratory timing matters because breathing can be aligned with simultaneously measured brain and body signals. Researchers can examine when inhalation and exhalation occur relative to neural activity, autonomic regulation, arousal, sleep, or behavior. This temporal reference also helps distinguish breathing-related variation from changes that might otherwise be misinterpreted in neuroscience recordings.
Researchers can derive respiratory rate, the timing of breathing phases, and relative changes in breathing depth. These measures provide a compact description of respiratory pattern rather than a standalone account of brain function. In an experiment, the resulting trace can be related to neural, physiological, or behavioral measurements to examine how breathing covaries with the process under study.
This monitoring is useful when studies examine brain function or cognition alongside breathing, and when investigators study autonomic regulation, arousal, sleep, or behavior. Its noninvasive format makes it suitable for adding a respiratory channel to such experiments, providing physiological context without requiring the belt to measure neural activity itself.
The belt provides a record of breathing-related fluctuations that can be inspected alongside physiological and neuroimaging signals. Researchers can use that correspondence to identify respiratory artifacts, meaning signal changes associated with breathing rather than the phenomenon of interest. Accounting for these periods supports more accurate interpretation of measurements related to brain function and cognition.
